Q

Discuss the function of erythrocytes, granulocytes, thrombocytes and lymphocytes.

A

Erythrocytes: Red Blood Cell’s. Contain hemoglobin and these transport oxygen and carbon dioxide to and from the tissues.

Granulocytes: WBC with secretory granites in its cytoplasm. “basophil”. Function is to fight off pathogens such as bacteria and fungi.

Thrombocytes: Platelets. Function is to stop bleeding by clumping and clotting blood vessel injuries.

Lymphocytes: WBC that function as part of the immune system. Properly respond to foreign invaders in the body.
