Question

Which of the following blood cells is compulsory for blood coagulation?

• A. Platelets
• B. Red blood corpuscles
• C. White blood corpuscles
• D. Lymphocytes

Answer 1

Answer:

A. Platelets

Coagulation is the process by which blood forms clots. It is an important part of homeostasis, the cessation of blood loss from a damaged vessel, wherein a damaged blood vessel wall is covered by a platelet and fibrin-containing clot to stop bleeding and begin repair of the damaged vessel. Platelets immediately form a plug at the site of injury, this is called primary homeostasis.
