5-25-10 "Chinks in Evolution 3"

What do you think of when you think of blood? Sticky red stuff that comes when you cut yourself? The liquid substance that runs in your veins? Maybe you take a more scientific approach and words like red blood cells or corpuscles come to mind.

What is blood? Blood is a complex compound that is made up of a yellow fluid called “plasma” or “liquor sanguinis,” gasses, and various types of blood corpuscles. There are three types of corpuscles: “colored” or “red” corpuscles (Erithrocytes), “colorless” corpuscles (Leucocytes), and Blood-platelets.
The red corpuscles are circular discs. These disc, do not adhere to each other or to the walls of blood vessels while in the body. Once removed, however, they clump together readily. They are also quite elastic and will change a bit in order to pass unobstructed through a vessel if need be.
Colorless corpuscles come in five varieties, each type with its own makeup. Eosinophile cells have course granules and a horse-shoe shaped nucleus. The smallest of the leucocytes is the Lymphocyte. The most common leucocyte is the Polynuclear cell, which gets its name from the tendancy of its nucleus to have two or three identical and attatched parts. The Hyaline cell is spherical and has a spherical nucleus. The last variety is a finely granular leucocyte with a lobed nucleus. Ineach millimeter of blood, there are over ten thousand leucocytes!
Blood-related (cardiac) organs begin to develop in human embryos at day 16 or 17 after conception. Blood cells form at day 21. From that day, the heart continues to pump blood through the body until the day that person dies.
Inside the normal human body, the blood is 96.8*F, has a specific gravity of 1’060, and flows easily. If there is a mistake in the genetic code, red blood cells may become sickle-shaped and cause anemia. When exposed to air, blood clumps together to form a clot. Were it not for the clot, a person could bleed to death from a small cut.
Do you see the amazing balance of God’s creation of blood? I have not even touched on how blood interacts with body tissue and organs! I have barely scratched the surface of what blood is and what it does! I have not described the differences between human blood and the various types of animal blood! How can anyone believe that such a delicately balanced, life-sustaining compound could have simply evolved? If just one aspect of blood were altered, life could not continue. People who have blood disorders have to live with extreme caution and have medical help in order to survive- how could “primitive” man survive in such a state? If only people would take the time to learn the complexity of God’s creation, there would be no question for his existence. The very blood that redeemed our souls on Calvary was a testimony to God’s creation.
