Question

Which of the following blood cells help in blood coagulation?
A. RBC’s
B. Lymphocytes
C. Thrombocytes
D. Basophils

Answer 1

Hint: Blood coagulation is also called blood clotting. Blood coagulation is a process which involves the formation of blood clots that is liquid blood is converted into a gel-like clot. It results in haemostasis. Various clotting factors, enzymes, and blood cells are responsible for the coagulation of blood.

Complete answer: Blood is the red colour liquid which is circulated in all parts of the human body for the exchange of gases and transfer of nutrients and metabolic waste. Human blood is composed of blood cells and blood plasma. Blood cells consist of erythrocytes (RBC), leukocytes (WBC), and thrombocytes. Thrombocytes are also called platelets. The iron protein called haemoglobin is present in RBC. The function of RBC is to distribute oxygen to each cell of the body. Leukocytes are responsible for the immune system of the body. White blood cells are further divided into eosinophil, basophil, monocyte, lymphocyte, and neutrophils. The lymphocyte is a specialized type of white blood cells. Natural killer cells, T cells, and B cells are included in lymphocytes. Basophil is a type of white blood cell. Histamine enzyme is secreted by the basophils when activated. Thrombocytes, which are also called platelets, play an important role in blood coagulation.
So, option C is the correct option.

Note: Coagulation is an important biological process as it stops the bleeding of blood. Any disorder in the process of coagulation causes disease such as haemorrhage, thrombosis, or bruising. In the case of liver failure, the production of coagulation factor is decreased which increases the risk of bleeding during surgery.
