Question
Chapter 43.3, Problem 1CC
Summary Introduction
To discuss: The functional deficiency of immune system if the thymus is absent.
Concept introduction:
Lymphocytes develop from stem cells present in the bone marrow. There are two types of lymphocytes. They are “B” and “T” lymphocytes. Maturation of “B lymphocytes” takes place in the “bone marrow” itself. Maturation of “T lymphocytes” takes place in the thymus gland.

If the thymus gland failed to produce thymic hormones, which population of lymphocytes would be affected?
If an individual failed to develop a thymus because of a genetic defect, what would happen to the immune responses mediated by antibodies and those mediated by cytotoxic T cells? Hint: Think how helper T cells and B cells are functionally related,
Lymphocytes that develop immunocompetence in the thymus are (a) B lymphocytes, (b) T lymphocytes.
