Solution
Introduction of thrombocytes:
Thrombocytes are also called blood platelets and are corpuscles that circulate within the blood with a life span of about 10 days.
When the endothelial lining of a blood vessel is injured, platelets in large numbers immediately attach to the injured surface and to each other, forming an adherent mass of platelets.
They are the first cells to reach the site of injury and initiate the process of blood clotting.
Function of thrombocytes:
The effect of the platelet response is to stop the bleeding and to form the site of the developing blood clot, or thrombus.
If platelets are absent, this important defense reaction cannot occur, and prolonged bleeding from small wounds will occur.
Platelets also contribute substances essential for the normal coagulation of the blood, and they cause the shrinking, or retraction, of a clot after it has been formed.
