Platelets
platelets
Platelets, small yellowish cells in the body, that group together to seal openings in blood veins.
Red blood cells form the clots, while white blood cells seal it from below.
The living part of blood is the white blood cells (leukocytes) and platelets. These cells are responsible for fighting infections and forming blood clots to prevent excessive bleeding.
The immune system has phagocytic cells called macrophages that eat up clots that result from tissue damage or allergic reactions. If these phagocytic cells are not doing there job then these clots do not get eaten up.
The test is done on a person's serum (the yellow liquid part of blood that separates from the cells after the blood clots ).
So that blood clots cannot form
Heparin is an anticoagulant substance produced by basophils and tissue cells. It helps prevent the formation of blood clots (thrombi) and dislodged blood clots (emboli) in the bloodstream.
Increasing the number of blood cells can lead to increased blood viscosity, which may slow down blood flow. This can potentially affect the delivery of oxygen and nutrients to tissues and create a risk for blood clots.

The white blood cells in your blood fight diseases, the red blood cells give you more oxygen if you are oxygen deprived, and the platelets form blood clots to keep you from losing to much blood when you get cut or bruised.
