Problem

Which of the following statement about B cells is incorrect?

A. They continually patrol the body using the body and lymphatic circulation.

B. They are produced and mature in the bone marrow.

C. They can bind the native antigen with surface immunoglobulin.

D. They secrete immunoglobulins.

Solution

The adaptive immune response depends on two types of white blood cells: T cells and B cells. These types of white blood cells are known as lymphocytes. Being blood cells, they are produced from the stem cells of the bone marrow. From the bone marrow, some lymphocytes migrate to the thymus and these become the T cells. B cells, on the other hand, are those that remain and mature in the bone marrow. In order for these lymphocytes to illicit an immune response, they must recognize their respective antigens, and would thus, require cell surface immunoglobulin receptors.
