Question

Which of these statements applies to leukocytes
A)They are responsible for the body's various immune defence strategies.
B)They spend most of their time in the body tissues.
C)They are all produced in the lymph nodes.
D)They are all matured in the bone marrow.

Accepted Answer

Leukocytes, also known as white blood cells, are responsible for the body's immune defence strategies against infection and diseases. They can be found in both the blood and body tissues, but their main role is to defend the body against pathogens. While lymph nodes do produce some types of leukocytes, not all are produced there. Similarly, while some types of leukocytes are produced in the lymph nodes, they are not all matured there. The majority of leukocytes are matured in the bone marrow.
