Question

Thrombocytes are essential for coagulation of blood. Comment

Answer 1

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.
