Q. The Life span of a W.B.C in man is
(1) 50 days
(2) 13 to 20 days
(3) 100 days
(4) None of the above
Answer: (2)
Explanation:
Option (2) 13 to 20 days is correct the answer.
There are three major types of blood cells: White Blood Cells (Leucocytes), Red Blood Cells (Erythrocytes), and blood platelets. The WBCs do not have haemoglobin in them, and they also are colourless.
On average, any human with a healthy body has about 6000-8000 WBCs in themselves. Leukopenia is a term that is used to define the low count of WBCs in the body, and a higher count can result in infections.
The lifetime of the WBCs is about 13 to 20 days in the lymph. The size of the WBCs is about thrice the diameter of the RBCs. They are mobile can they help in the production of antibodies.
