Responsible For Blood Clotting

PLATELETS / RBC's
The main function of platelets, or thrombocytes, is to stop the loss of blood from wounds (hematostasis). To this purpose, they aggregate and release factors which promote the blood coagulation. Among them, there are the serotonin which reduces the diameter of lesioned vessels and slows down the hematic flux, the fibrin which trap cells and forms the clotting. Even if platelets appears roundish in shape, they are not real cells. In the smears stained by Giemsa, they have an intense purple color. Their diameter is 2-3 µm about, hence they are much smaller than erythrocytes. Their density in the blood is 200000-300000 /mm3.

Red blood cells are responsible for gas transport. Platelets are cell fragments specialized for clotting. Leukocytes are only transient passengers in the blood, migrating across blood vessels into all other tissues where they function in immune defense.

the red cells. they have a high viscocity (cant remember if that is spelled right, but it is the resistance to flow) when it reaches the air outside the molecules and cools down. It is proportional to the amount of blood that is being pumped and the size of the wound.
