Blood Clotting Design

Blood Clotting Design

A couple of days ago, I accidentally sliced the tip of my finger with a sharp knife. It bled a lot for a while, but in a short time, the bleeding stopped. The bleeding probably helped cleanse any debris from the wound, but I didn’t want the bleeding to continue. If our blood did not clot, we could bleed to death from even a small injury. Blood clotting design, or coagulation, is a very complicated process that scientists have studied for years.

The process begins when a puncture to your skin injures a blood vessel exposing blood platelets to the collagen beyond the blood vessel’s lining. The platelets immediately bind to the collagen and each other, forming a temporary plug. This starts a whole series of complex chemical reactions involving proteins and enzymes called clotting factors.

A cascading series of a dozen steps must take place for coagulation to complete. The result is the creation of fibrin strands which strengthen the platelet plug and stop the bleeding. If any single factor of the clotting process is missing, the clot does not form, and the bleeding continues.

Hemophilia is a genetic defect that omits a clotting factor. It disrupts the process of blood clotting design such that people with hemophilia may bleed uncontrollably from even a small wound. This is an extremely simplified summary of the coagulation process involving a dozen factors requiring specific proteins and enzymes that must happen in a particular order.

Without blood clotting, humans and other mammals could not have survived. All of the clotting factors had to be present at the beginning of mammal and human life, meaning that the coagulation process could not develop gradually by chance. The fact that our blood clots when we are injured is another evidence of design by an intelligent Creator.

What Your Body Does in a Day

What Your Body Does in a Day

Own Olbricht sent us this summary of what your body does in a day. We thought it was worth considering the fantastic abilities of the bodies God has given us.

*Every day your heart pumps approximately 2,000 gallons of blood through its chambers.
*On average, your lungs take in 17,000 breaths a day with a typical lung capacity of roughly six quarts of air.
*Your brain processes over 50,000 thoughts a day – 35-48 thoughts per minute.
*Your stomach lining has cells which produce an alkaline substance every few milliseconds to neutralize stomach acid. The stomach would dissolve itself without its lining.
*Your eyes blink 28,000 times a day, with each blink lasting 1/10th of a second.
*Your body’s energy system expels enough heat to light twenty-five 100-watt light bulbs every day.
*Your skin is the largest organ of your body, and you shed a million skin cells every day.
*Your hair grows a millimeter a day. The average adult’s full head of hair consists of 100,000 strands.
*Your liver filters 1.53 quarts of blood every minute, and every day it produces a quart of bile to help digest food.
*Glands in your mouth produce more than a quart of saliva every day.
*Every minute your kidneys filter 2.2 pints of blood or 3168 pints per day. They expel 2.5 pints of urine every day.
*The average person will eat over 50 tons of food in a lifetime.


What your body does in a day is an excellent testimony to God’s wisdom, intelligence, power, and design.

Your Skin Holds Everything Together

Your Skin Holds Everything Together, but that's not all

You can go online and get all the factual information you want on every part of the human body. Put in the word “skin,” and you will be amazed at how much information there is about human skin. One comic said, “Your skin holds everything together.” In truth, it does much more than that.

We tend to classify humans based on their skin color, but our skin color is related to the needs of the body. Black objects radiate heat more efficiently than white objects. Take two identical cans and paint one black and the other white. Heat them to the same temperature and then let them sit in an insulated environment. The black can will cool off faster than the white can. Dark skin color is due to a biological pigment called melanin. Melanin absorbs ultraviolet light and thus protects the body. People living in tropical areas where they are exposed to more heat and ultraviolet light have more melanin than people living in cooler regions. There is, therefore, a latitude effect on skin color.

The more you study the design of your skin, the more amazing it is. One square inch of human skin contains nearly 20 million cells and 625 sweat glands. That square inch of skin can also have as many as 65 hairs, 19 feet (5.8 meters) of blood vessels, and 19,000 sensory cells. To limit bleeding, blood vessels in your skin temporarily shrink instantly if the skin is cut or if pressure is applied. Your body sheds skin cells when they die and replaces them with new ones. Three-quarters of the dust floating around your house is made up of dead skin cells.

So, if you think your skin holds everything together, and that’s all, you would be wrong. Your skin, the largest organ in your body, does a wide range of things that help you to stay alive and comfortable. When David wrote, “I will praise you, God, for I am fearfully and wonderfully made” (Psalms 139:14), he was not aware of many things about our bodies that we know today. As we look at ourselves with tools such as microscopes, we see design in the construction of our bodies that David could not have imagined.

There is a wonderful book published in 1989 and now out of print that gives many other examples of the incredible designs we see in our bodies. The title is The Compass in Your Nose and Other Astonishing Facts About Humans by Marc McCutcheon and published by Jeremy Tarcher, Inc.

Largest Body Organ

Largest Body Organ - Skin
As you think about all of the organs in your body and how important they are, don’t forget the largest body organ. It’s also the one that is most visible—your skin.

Have you ever considered how incredible your skin is? The hands of a laborer may be rough like sandpaper, but his abdominal skin could be smooth and soft. The calves of your legs have skin bonded tightly to a muscle layer. The skin on your elbow can be lifted loosely in rolls. If you used a microscope to examine the skin of our scalp, lip, heel, and finger, you might think you were studying sample from different species.

Your skin is the largest body organ, and there is no other organ like it. It flexes, folds, stretches, and bends around joints. It’s sensitive to touch. The skin of your finger pads is sensitive enough to detect a grain of dust on a smooth surface or read Braille letters in a book. When you blush (something that only humans do), the blood vessels of your skin suddenly rush many times more blood than usual. Your skin even regenerates itself when it’s damaged.

Your skin shows emotions, cools and insulates your body, protects you from germs, serves as a receptor for all kinds of stimuli, and gives you that unique appearance. We often cut off the hair growing out of our skin or add some substance to soften and beautify our skin. We seldom take a moment to realize what a fantastic organ it is.

Of all the vital organs of your body, your skin is the most visible. Skin color or texture may vary from person to person, but regardless of those factors, it protects what is inside. Your largest body organ is another incredible design by a Master Designer.
