The Creation of the Human Body

The 139th Psalm describes the creation of the human body by God and how very much God loves us and thinks about us every day.

Psalm 139:13-18: (NASB)
​
13 For You created my innermost parts;
You wove me in my mother’s womb.
14 I will give thanks to You, because I am awesomely and wonderfully made;
Wonderful are Your works,
And my soul knows it very well.
15 My frame was not hidden from You
When I was made in secret,
And skillfully formed in the depths of the earth;
16 Your eyes have seen my formless substance;
And in Your book were written
All the days that were ordained for me,
When as yet there was not one of them.
17 How precious also are Your thoughts for me, God!
How vast is the sum of them!
18 Were I to count them, they would outnumber the sand.
When I awake, I am still with You.

This Psalm proclaims that God created each of us special, and we are very special to Him. This Psalm explains the following information about the human body.

THE UNIQUENESS OF YOUR BODY:

There are 100 trillion cells in the human body. Each cell contains about 3.2 billion nucleotide pairs, and your body contains about 25,000 genes. You are totally unique and have never existed before and will never exist again. The probability that you would be born is one in trillions.

(Editor's note: A nucleotide is a molecule that carries genetic information, similar to a letter in the English alphabet. The billions of nucleotides thus create sentences that literally compose novels upon novels of complex specific information that tells the cell how to assemble perhaps the most essential and diverse type of molecule in the human body, proteins.)

Every cell needs oxygen every minute and the circulatory system provides this oxygen.

The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood (https://kidshealth.org/en/teens/blood.html) throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs (https://kidshealth.org/en/teens/lungs.html) to pick up more oxygen. This cycle repeats over and over again.  

By adulthood, we each have 60,000 miles of blood vessels inside our bodies – that's more than twice the distance around the world. Those vessels keep blood flowing, supplying your tissues with oxygen and nutrients, and keeping your organs, including the heart, healthy.  Your heart beats 2 billion times in a 70 year lifetime.


THE HUMAN BRAIN:

The human brain weighs 3 pounds and represents 2% of the weight of the body.  It is 75% water and is the fattest organ in the body.  It is 60% fat.  The brain is the seat of intelligence and is the crown jewel of the human body.  It can process 400 billion bits of information per second and runs on 12 watts of power (20% of the body’s energy).

The primary functional unit is a microscopic cell in the brain called the neuron. All sensations, movements, thoughts, memories, and feelings are the result of signals that pass through neurons. 

The brain has 86 billion neurons and 400 miles of capillaries (blood vessels).  

These neurons make 10 quadrillion calculations per second.

The neurons make 500 million connections through their branch system performing a dazzling array of mental processes every second including sensations and perceptions; how we reason; how we think; our emotions; our mental images; our attention span; learning; memory which is essentially a pattern of connections between neurons.

A piece of brain matter the size of a grain of sand has 100,000 neurons with 2 million axons (transmission lines from the neurons) and one billion synapses (small gap at the end of the neuron that allows a signal to pass from one neuron to the next.

THE MIRACLE OF EYESIGHT:

In short, the eye is nothing short of a wonder organ, as it can control the amount of light it takes in through muscles in the iris. These muscles contract and relax to alter the size of the pupil. The light first passes through the cornea, and then moves into the lens. This part of the eye bends the light, ultimately onto the retina.

The powerhouse of the eye, the retina is covered in millions of light-sensitive receptors known as rods and cones. Each receptor contains pigment molecules. These ultra-sensitive receptors are shapeshifters when hit by light. In response, they trigger an electrical message that travels to the brain via the optic nerve.

Vision is truly a miracle, when you consider that our eyes are only able to produce two-dimensional images. The brain’s advanced processing means it’s able to build these flat pictures into a 3-D view. 

Our eyes are positioned about two inches apart, so each sees the world from a slightly different angle. The brain compares the two pictures, using the differences to create the illusion of depth.

Color is another variable entirely. Open your eyes, and you experience a wide variety of colors, but the reality is that you can only detect three different wavelengths of light, corresponding to green, blue, and red. Combining these three signals in the brain creates millions of different shades. Can you imagine how different life would be if you just saw in green, red and blue, like our pets do?

So, as you can see, vision is really a result of your eyes and brain working together to allow you to take in the beauty of the world. 

Eyes are so intricate, they say, that it stretches credibility to suggest they evolved through the selection and accumulation of random mutations. Charles Darwin was well aware of the argument. In his work On the Origin of Species he admitted that eyes were so complex that their evolution seemed “absurd to the highest degree”.
