Question

Thrombocytes are essential for coagulation of blood. Comment.

Answer 1

Blood is a connective tissue. It has many cellular components. Thrombocytes or platelets are one of them.

Thrombocytes or platelets are found in blood. Their number in the blood is 250,000/cubic mL of blood. They are formed in bone marrow and their lifespan is one week.

When an injury is caused in the blood vessel, bleeding starts, and the platelets are disintegrated to release the clotting factor 3, called thromboplastin. The presence of $C{a}^{2+}$ ions activates prothrombokinase. A series of reactions ultimately occurs which causes blood to clot and plug the injured blood vessel thus preventing further loss of blood.
