platelets
The process of reducing blood is called cloting of blood or coagulation of blood
Coagulation is the process by which blood cells begin to clot to prevent further blood loss. When the body senses it is losing blood the platelets in the blood rush towards the wound to begin clotting the blood.
The blood coagulation which you are referring to has several stages and types. The main cells involved directly are thrombocytes, while endothelial cells etc may also play a role. There are also soluble factors of the blood involved. (see coagulation cascase) See http://en.wikipedia.org/wiki/Coagulation
coagulation of blood is what happens to blood when the body dies or once it gets to air. it clots coagulation is a process of combination of colloidal particles (size less than one micron) and destabilize from its normal form.
THROMBIN
The prothrombin time (PT) test measures how long it takes for blood to clot. This test evaluates the coagulation factors involved in the extrinsic pathway.
Blood coagulation can explain the concept of coagulation. When we have a cut in our skin, the blood loss would be stopped by fibrin clot formation. This is formed by series of pathways formed by blood clotting factors, thrombin and fibrin.
The process is known as coagulation.
Platelets are the cellular fraction in blood helps to clot the blood. This process is also known as coagulation.
Vitamin K is important in blood coagulation.
Coagulation: clotting of the blood. Stroke: a restriction of blood flow caused by clotting of the blood.
