Which of the following statement is correct regarding blood cells?
1 Ahealthy individual has$12-16\text{gms}$ of haemoglobin in every $200\text{ml}$ of blood.
2 RBC as an average life span of 120 days after which they are destroyed in the spleen.
3 Neutrophils and basophils are phagocytic cells which destroy foreign organisms entering the body.
4 A reduction in the number of WBC leads to clotting disorders which will lead to excessive loss of blood from the body.
Explanation:
(b) Ahealthy individual has $12-16\text{gms}$ of haemoglobin in every $100\text{ml}$ of blood. Neutrophils and monocytes are phagocytic cells which destroy foreign organisms entering the body. A reduction in the number of platelets leads to clotting disorders which will lead to excessive loss of blood from the body.

Which of the following cells do not exhibit phagocytotic activity?
1 Monocytes
2 Neutrophil
3 Basophil
4 Macrophage
Explanation:
(c) Basophils are the least common granulocyte, only composed of $0.01\text{ }\!\!%\!\!\text{ }$ to $0.3\text{ }\!\!%\!\!\text{ }$ of the circulating white blood cells. These are involved in specific kinds of inflammatory reactions, especially those which cause allergic reactions and do not exhibit phagocytic activity. Monocytes on the other hand, migrate from blood stream to tissue and differentiate into resident macrophage, like kupffer cells in liver and neutrophils target bacteria and fungi. Macrophages are also phagocytic in nature.
