Weegy: When blood vessels are cut or damaged, the loss of blood from the system must be stopped before shock and possible death occur. [ This is accomplished by solidification of the blood, a process called coagulation or clotting. A blood clot consists of a plug of platelets enmeshed in a network of insoluble fibrin molecules. There are two processes that can initiate clotting: A very rapid process the so-called extrinsic pathway (upper right) and a slower but larger intrinsic pathway (upper left). ] (More)

Weegy: Serum is the watery portion of an animal fluid remaining after coagulation. (More)

Weegy: Sir/Madam, Vitamin K is a necessary participant in synthesis of several proteins that mediate both coagulation and anticoagulation. Vitamin K deficiency is manifest as a tendency to bleed excessively. [ Indeed, many commercially-available rodent poisons are compounds that interfere with vitamin K and kill by inducing lethal hemorrhage. ] User: Does calcium aid in blood coagulation? Weegy: in addition, calcium assists in the process of blood clotting and helps prevent the accumulation of too much acid or too much alkali in the blood. It also plays a part in secretion of hormones. [ It affects neurotransmitters, nerve transmission, muscle growth and muscle contraction. ] User: What does the plasma protein Albumin do? Weegy: Albumins are commonly found in blood plasma, and are unique from other blood proteins in that they are not glycosylated. [ Substances containing albumin, such as egg white, are called albuminoids. A number of blood transport proteins are known to be evolutionarily related, including serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin. ] (More)
