Are we already on part five? We’re already on part five! Where does time go? Hmmm…note to self. Another blog topic for another day is the elusive subject of TIME.
Part Five. The Amazing Human Body. We’ve covered the brain, eyes, ears and nose, the heart, and the lungs. Now we are ready for other organs. I’m lumping them together like I did for eyes, ears, and nose. While the series could cover hundreds of posts right down to the hairs on our head and the toenails on our feet and everything in between, I am trying to be somewhat conservative and sensitive to the number of parts published in the series. There is a lot to cover and so cannot (or should not) be done in one or two posts, but likewise should not drag on either. A comfortable point where a wrap-up is both useful and feels good is an appropriate goal to set. So, let’s begin Part Five knowing the end of the series is approaching.
It takes a lot of collaboration amongst the innards of our bodies to keep us in top form. Yes, I said innards. Innards, guts, insides, viscera, all those internal organs that are separate from the brain, heart, and lungs. Remember, you aren’t just you on the outside. You are you on the inside too.
Specifically, the facts in this post touch on the skin (you can fact-check me whether or not the skin is considered an organ), the liver, kidneys, intestines and the pancreas. There are more organs, like the appendix, bladder, gall bladder, spleen, thymus, etc. to be sure, but again, my goal isn’t the number of posts or facts I can display in a potentially endless series. The goal is to manifest an opportunity for the readers to pause and reflect enough times and eventually make them go, ‘hmmm, what that said’ and then they can have their own little cause for considering creation versus evolution. So, here are those facts about some of the other organs which make up the human body.
Human skin is completely replaced about 1,000 times during a normal life span.
The human skin also has about 1,000 different species of bacteria on it.
Each day, the kidneys process about 50 gallons of blood in order to filter about two quarts of waste and water.
The highest blood flow occurs in the kidneys, not in the heart as many would imagine.
Stomach acid can dissolve metal. If it came into contact with your skin, it would burn right through it.
The lining of a person’s stomach is replaced every four to five days to prevent it from digesting itself.
The liver is the only organ which can regenerate itself.
The liver detoxifies the body from harmful chemicals, breaks down drugs, filters blood, secretes bile, and produces blood-clotting proteins.
Your body has anywhere between two and five million sweat glands.
The pancreas can taste sugar via specialized taste receptor cells to detect the presence of sugar. It is used to balance out hormones and maintain healthy glucose levels.
If your intestines were removed and laid out flat, they would cover two tennis courts.
While it’s unknow how it is done, the intestines are sentry guards in allowing good things (food, water, vitamins, good bacteria) to pass into them, and block bad things (parasites and bad bacteria) from passing into them.
Well, what do you think? Innards are pretty cool stuff, huh? After reading this or any of the previous posts, are you contemplating how the human body is its own proof in creation? Feel free to respond with any comments or feedback. Having a safe place to offer and share honest thoughts and opinions is a cool thing, and I truly hope people can see this blog as just such a spot.
Also, be sure to come back and catch the remainder of the series. Before we get to that wrap-up, there is a section to do on bones, bodily systems, and a general catch-all category.
Before signing off, I must obey the blogging etiquette and find a tie-in related to my blog’s purpose…the connection and love between man and dog. How can I tie these together? Let’s try this haiku, by me, of course.
Sharing – this is interesting and a treat too. Enjoy and God Bless.
Indianapolis Recorder, November 23, 1929, 2, accessed Hoosier State Chronicles.“The Long Distance Telephone is the Modern Thanksgiving Greeting:” this 1929 Indiana Bell Telephone Co. advertisement will certainly resonate with Hoosiers, who are finding alternative ways to spend the holidays during the pandemic. The ad continues—and we relate—”Distances, however, and the press of modern affairs sometimes…
During this week of gratitude, appreciation and Thanksgiving, one thing I am so hopeful for is that you are able to count your health as a blessing. Health is often taken for granted by many, and also wished for by many others.
The craziness of COVID has likely emphasized this in many households. At what is normally a time of gathering with family and friends, we must now be mindful of viruses and infections. Appreciation of health is replaced with worry of disease and potential contagions. Instead of opening our arms and embracing loved ones, we must display the ‘stay back six feet’ signal with a stiff arm and a stop-sign hand.
Yet I still wish you a Happy Thanksgiving and Happy Health, even if we can’t embrace one another. If you are indeed a blessedly healthy person, then you are able to breathe in and breathe out (while wearing your COVID mask if around others, of course), breathe in and breathe out, breathe in and breathe out.
You do it without thinking, this thing called breathing. It’s automatic and repetitious. It’s quiet and comforting. It’s reviving and healing. It’s free therapy for the taking, and you have your lungs to thank for it.
As we continue the series on The Amazing Human Body, let’s talk about our lungs. The following factoids happen to be some of the realities that astound me the most about human existence. The lungs are a truly remarkable apparatus and sometimes, unfortunately, are much underrated for the purpose they serve. Here they are.
The surface area of the human lungs is about equal to the area of a tennis court.
An adult person performs around 23,000 inhalations and exhalations per day.
Humans exhale up to 17.5 ml of water per hour.
The lungs remove oxygen from the air we inhale and transfers it to our blood where it can be sent to our cells.
The lungs also remove carbon dioxide from the returning blood so it is eliminated from our body when we exhale.
The air we breathe contains 21% oxygen, but our bodies only use 5%; the rest is exhaled.
Lungs can float on water – the only organ in the body capable of doing so.
The lungs are able to float because, even after exhaling, they contain about one liter of air. This means lungs are not hollow as some believe.
The lungs are encapsulated within the rib cage for protection, and are connected to the spinal cord in the back and to the chest bone in front.
Human lungs are asymmetrical. Perfectly designed to make room for the heart, the right lung is larger than the left lung.
Changes in breathing without intention is due to the brain’s control telling the lungs how much to inhale or exhale.
Even though you cannot see your lungs, your mouth is directly connected to them via the wind pipe and esophagus.
As a fetus, we have fluid in our lungs. Quickly after birth, usually around ten seconds, we take our first breath of air.
Breathing deeply into the lungs eases pain and stress.
Special cells produce mucous as a self-protecting mechanism against pollutants and contaminants. The mucous also helps prevent the lungs from drying out.
Coughing around ten times per day is very normal for an average, healthy individual.
The best solution to cure ailing lungs is to perform simple cardio exercises. Your lungs want to breathe and heal!
Breathe in. Breathe out.
See? I told you the lungs were remarkable. Your whole body is remarkable. You are remarkable.
Hopefully you are getting into the groove of the series and are starting to really appreciate the message behind it. Remember the main goal of the series is to challenge you to consider the argument of creation versus evolution, and by providing some scientific facts about the intricacies and nuances of the human form, we are setting the foundation for you to proceed in your deliberation.
As you do so, be thankful this week for your health and the health of your family and loved ones. Specifically, be thankful for every breath you take.
So as not to leave out our furry canine friends, be thankful too for every doggy breath that wakes you in the morning, every doggy breath that kisses you good night, and every doggy breath that asks you to share your snack as said doggy climbs up beside you and stops your hand half-way to your mouth.
Happy Health and Happy Thanksgiving to everyone. God Bless!
Here we are, all primed and ready for part three of my series on The Amazing Human Body (Or Why I Believe in Creation). For this section of the series, we will be highlighting the eyes, ears, and nose. If there are any ENTs in the audience, or if you know of an ENT who would enjoy this, please feel free to comment and share!
To bring everyone up to speed, I’m currently blogging on facts about the human body which are well, not just interesting in a ‘oh, hey that’s cool’ kind of way, but rather in a way that says ‘wow, that is truly amazing!’ Even if it’s something you already knew, the challenge is for you to regard the fact in a contemplative manner of evolution versus creation.
Really think about the fact or facts at hand (whether taking this challenge one sentence/piece at a time or one section at a time), then consider…is evolution something with the actual ability to make this happen, or is creation responsible? Which makes more sense? Which definition and purpose fits the end result of the all-amazing human body?
Of course, I’m biased. I ultimately see only one answer. But two things about blogging this and putting it out there for all to read. One: I’m still interested in what others believe and in hearing why they believe so in a conversational, non-debating kind of fashion. Two: If there is something in my blog that helps lead a non-believer to become a believer in creation, well, that’s a good thing.
So whether you choose to believe in evolution or creation, join me in celebrating these amazing facts about the human body, specifically the eyes, ears, and nose.
The only part of the human body to have no blood supply is the cornea of the eye. It receives oxygen directly from the air.
The human eye can distinguish ten million different colors.
The retinas cover about 650 square mm and contain 137 million light-sensitive cells: 130 million are for black and white vision, and seven million are for seeing in color.
Seeing is such a monumental part of everyday life that it requires half of the brain to accomplish vision.
While transplants of various body parts are normal, there is as of yet no way to transplant the eyeball. The intricacies of the optic nerve and its connection to the brain is so complex and sensitive that reconstructive surgery is not possible.
Cells in the eyes are shaped differently for different purposes. Rod-shaped cells see shapes, and cone-shaped cells see color.
The fastest muscles in the human body are the ones that make the eyes blink. They can contract in less than one-hundredth of a second.
The inner ear is surprisingly small, about the size of a pencil eraser.
Yet the ear can detect sound waves as low as 20 Hz and as high as 20,000 Hz.
Ears are self-cleaning.
The outer ear never stops growing during human lifetime. (Is this a hint to listen more carefully?)
The ear contains more than 20,000 hair cells. Without these hairs, we would not be able to hear.
Ear don’t just help us hear. They help us to maintain balance when standing and walking.
The Eustachian tube in the ear is responsible for striking balance needed between atmospheric pressure and body pressure.
Our sense of taste not only relies on taste buds, but also on a nerve in the ear. The chorda tympani connects the taste buds to the brain by navigating through the middle ear.
The nose can recognize about a trillion different scents.
Humans have approximately twelve million olfactory receptor cells to help us detect smells.
The nose and sinuses can produce up to a quarter gallon of mucus each day.
Eyes, Ears, and Nose – Amazing Facts
That last item is a bit gross, especially considering that I usually try to end on a more pleasant note. Oh well. Think about your own noses, or better yet, your dog’s nose. Molly had a cute little button nose, which is a much more appropriate transition than mucus.
Anyway, I truly hope you are as inspired by these scientific facts on the human body as I am. More importantly, I hope you keep tuning in for more, as we are not anywhere near being done. We still have the lungs, other internal organs, bones, and even more to cover! Once we get through everything, I’ll do a recap to tidy it all up for everyone.
One more thing. As you give in to reflection on your amazing human body, take a moment in turn to look at your furry friend and reflect on his or her amazing attributes. The way your little pet-pal is so in tune and responsive to your thoughts and actions is no accident. There is purpose in the way your pet connects with you, and such purpose starts with something amazing. A brain, a heart, and eyes, ears, and a nose. And I don’t mean just yours. So, after the final recap mentioned above, expect one more article on how animals are also part of God’s perfect creation.
We are now ready for part two of The Amazing Human Body series. This series is a simple accounting of some of the wonderful and miraculous machinations of the human body.
Beyond the accounting of it though, I truly hope it inspires you to think about how your body came to be in this form and how it exists in harmony with nature and earth. Mankind sometimes messes up the harmony, I know, yet the harmony still exists. A perfect example is that we breathe in oxygen and breathe out carbon dioxide. Trees and plant life breathe in carbon dioxide and breathe out oxygen. Win-win. Harmony. Balance. Perfection.
Can evolution masterfully and perfectly sort atoms, molecules, DNA, and space, energy, and mass into such harmony and balance and life? Thinking, reasoning, constructive life? Being that evolution begins with random chaos and no order or rationality at all (evolution cannot create, rationalize, or put things in specific order for any purpose at all), then how can it result in a world of beauty and harmony to be enjoyed by its inhabitants?
This question is not meant to argue with a non-believer on the subject of creation versus evolution. As I said in part one, science is a friend, and there are elements of the science world to support the theory of evolution. Rather, the question is meant to offer a pondering at the deduction of evolution as a non-believer’s final answer.
Let’s proceed to part two which covers the human heart.
In order to work, the human heart’s physiology requires elements of both electricity and plumbing.
The electrical system controls the rhythm of the heart and is called the cardiac conduction system.
The plumbing system includes the aorta, which is as large as a garden hose in circumference.
The human heart pumps 182 million litres of blood during an average lifetime, or about 2,000 gallons per day.
The pressure of a human heart is enough to pump blood to the fourth floor of a building.
There is anywhere between 60-100 thousand miles of blood vessels in the human body. If laid end-to-end, they would be long enough to travel around the world more than three times.
There are some capillaries that are ten times thinner than a human hair.
A kiss increases the pulse to 100 beats or more per minute.
The sound of a heartbeat is created when the valves of the heart open and close.
Heart cells do not divide themselves, which means heart cancer is extremely rare.
Laughing is good for the heart because it reduces stress.
The human heart
Again, these are all scientific facts about the human heart. You can easily do quick google searches to verify each statement, or look them up in medical journals, or if you still have biology books from school in your possession, look there.
Human existence is due to more than just a haphazard meshing of cells and atoms to create a random blob that would someday on a whim with some sort of fortuitous electrical charge turn itself into the beginnings of life millions of years ago. So yes, science is helping us out to prove creation over evolution. Believe the science. Your body is an amazing thing and it was created with purpose and care to live in harmony with the rest of the created world.
Where else does harmony live? Inside our human hearts. The hearts which pump 2,000 gallons of blood per day. The hearts uniquely made with electrical and pumping systems. The hearts which benefit from kissing and laughter.
Go kiss someone you love. Laugh with them. Feel good knowing you are specially created, for indeed you are. Feel free to share the kissing and laughter with your dog too. There are even extra health benefits there.
This is an amazing world full of amazing things and we humans are amazing creatures. I’ve always believed in creation versus evolution, though the theory of evolution does intrigue me to a point. Science is a friend, after all, and I would never poo-poo a friend or a friend’s beliefs. I would, however, offer up my own basis for my beliefs where warranted. Interesting thing about saying that though…I have finally floundered upon my best offering yet as to why creation trumps evolution. The human body itself!
Yes, the human body, YOUR human body, is the only earthly and scientific proof a person needs to understand and believe in creation.
Take a look at part one of these amazing facts about the human body. It’s a long list, so I’m breaking it down into pieces. Feel free to grab a cup of tea or coffee for this ride and tune back in regularly for future posts until we finish up the series.
Also take note. If you are a cynic, doubter, nay-sayer of any kind, that’s okay. Accept my challenge though. I challenge you to be still for a moment and do more than just read the list. Make a commitment to yourself to actually contemplate the list one sentence or section at a time. Take days, weeks, or even months if needed. There shouldn’t be an epiphany at the first reading of the first sentence or two. The encouragement is to muse over it, let it sink in, hypothesize its merits over time and then decipher it for your own decision-making use. These are all undisputed and scientific facts about the human body. Nothing here is made up. But you may need time to let science (yes, science) catch up to your pre-conceived mind and help said pre-conceived mind explore other possibilities beyond evolution.
Ask yourself what is each piece of evidence really saying about you and your body? Is it something you already knew, once knew and forgot, or is it something you’re realizing or learning for the first time ever in your life? Maybe you have always known the fact, but are you thinking about it differently now, in terms of how your body works and functions? Is it changing your perception of how you believe mankind is able to think, do, and exist? Is it simply offering an element you had not thought of before? Pointing to evolution as factual, could evolution really be the reason leading to this amazing fact about your body?
Keep questions like this popping into your head as you go through this exercise; it will help you along the way.
Here we go. Part one will cover the human brain.
The brain is the control center, sending and receiving signals through the nervous system and secreted hormones. It is responsible for thoughts, feelings, memories, and general perception of the world.
The brain is the fattiest organ in the body. This is why healthy fats are vital for brain health to stabilize the cell walls in the brain.
The human brain will triple its size in the first year of life.
The human brain has a memory capacity equivalent to more than four terabytes on a hard drive.
By the end of a person’s life, he/she can recall on average about 150 trillion pieces of information.
The human brain contains approximately 100 billion neurons.
There are so many nerve cells in the human brain it would take 3,000 years to count them.
Nerve impulses from the brain travel at a speed of 274 km/h.
Approximately 100,000 chemical reactions occur in the human brain every second.
A human brain generates more electrical impulses in a day than all the telephones of the world combined.
While awake, the brain produces enough electricity to light a small bulb.
Even in sleep, the ear continues to detect sound. But the brain learns to ignore the sounds so the body can continue to sleep soundly.
Dreams are proof that your brain is working even when you are sleeping. The average human has about 4-7 dreams per night.
And my human brain is remembering and recalling that I need to tie back to my book, I Kissed a Dog and I Liked It. So, here’s a preview for Part Two of The Amazing Human Body series covering the heart: A single kiss increases the pulse to 100 beats or more per minute. There’s an energy boost and recharge for you. Feel free to kiss someone, or your dog, for a quick picker-upper. Just make sure it is someone or a dog you know well enough.
