If you’ve ever cut or scraped yourself and were able to stop the bleeding, you can thank the tiny discs in your blood known as platelets. They are about 1/5 the size of red blood cells, colorless and irregularly shaped particles that float around in your blood waiting for a breech in the skin to occur.
When a cut or scrape does happen, the blood is exposed to the air. When the platelets come in contact with the oxygen in the air, they react and begin to break apart. With the presence of a protein known as fibrinogen, along with calcium and vitamin K, the platelets produce fibrin. Fibrin is a threadlike substance that forms a mesh, much like a fishing net, across the wound opening. When enough of the mesh net is in place, it begins to catch the red blood cells and form a clot. As a clot dries, it forms that ugly brownish hard covering that we refer to as a scab.
If any of the components for clotting (calcium, vitamin K, fibrinogen or platelets) are absent, bleeding generally continues and a person could easily bleed to death.
But platelets may also have a negative impact on a person’s health. Due to their sticky nature, it appears that platelets may adhere to the outside of tumor cells released into the blood stream. With a coating of platelets, the tumor cells may actually be hidden from the body’s immune system, allowing them to be carried to other parts of the body and spread the tumors.
Scientists and doctors know a great deal about red blood cells and other parts of the blood, but they really don’t know that much about platelets or exactly what makes them work. That is until now.
Chemist Christy Haynes heads the Haynes Research Group at the University of Minnesota. Haynes and her group are the first ones to begin to unlock the chemical messaging system of platelets. This is allowing them to learn what signals make them react in the ways they do and how they relate and react with other parts of the blood.
The research group is hoping that their unlocking the messaging system of platelets will lead to ways to control storage pool disorders, how to use platelets in future therapeutic procedures and hopefully how to prevent them from making tumor cells.
What’s amazing about platelets is the complexity of the clotting system and their chemical messaging system. Evolutionists want you to believe that platelets and the clotting system are the products of random chance evolution, but ask them this question:
How many people or animals bled to death before they evolved platelets, fibrinogen and their reaction with oxygen, calcium, vitamin K and chemical messaging system?
What are the odds of all of these parts evolving at the same time to allow an individual to survive long enough to reproduce and pass the traits on to the next generation?
Any bio-statistician who carefully analyzes all of the mechanisms and molecular processes necessary for clotting to have evolved would tell you that the probability would be virtually zero or as close to zero as possible.
If the probability of clotting is zero, what alternative is left?
I praise you, for I am fearfully and wonderfully made. Wonderful are your works; my soul knows it very well.

It is with great sadness that we have watched the events surrounding the starvation-induced death of Terry Schiavo. At no time in modern history has it been more obvious that the salt once prevalent in American society has lost its saltiness. Basic understanding of the Scriptures and deference to the authority of Gods holy Word no longer guide the decision-making processes behind modern courts and communities, or even many Christian churches and homes.
This compelling, illustrated lecture was presented by anatomist Dr. David Menton at Answers in Genesis’ Defending the Faith conference in Ft. Lauderdale, Florida. You have never seen a presentation regarding the value and dignity of human life that is as powerful, and as respectful as this.
Dr. Menton explains that the question is not when does life begin, but when does a person begin? He explains from anatomical science and biology the truth of Psalm 139:13-16 where God says that He weaves us together in the womb. The DVD also illustrates the amazing and intricate design of the womb and the processes of fertilization, implantation, embryonic development and birth itself. Dr. Menton reveals that each of these is a series of miracles (irreducible complexities) that cannot be explained by chance and random processes. Even more important, as Dr. Menton explains with grace and sensitivity in the wrap-up of the video, is the second birth process of salvation explained in John 3.
