Question
Damage to thymus in a child may lead to
a reduction in haemoglobin content of blood
a reduction in stem cell production
loss of antibody mediated immunity
loss of cell mediated immunity
Solution
D.
loss of cell mediated immunity
Thymus gland is located in the upper part of thorax near the heart. It is a bilobed, pinkish gland. It secretes thymosin hormone, thymic humoral factor and thymopoietin.
Proliferation of lymphocytes and differentiation of these lymphocytes into a variety of clones are induced by these factors. These clones are differentially specialized to destroy different specific category of antigens and pathogens. Therefore, thymus gland brings fourth T- lymphocytes for cell mediated immunity.
