Hints & Solutions
(d) The thymus is a major gland of our immune system. The thymus is responsible for production of $T$ (thymus dervied) lymphocytes from immature lymphocytes, a type of white blood cells responsible for cell mediated immunity. Cell mediated immunity is extremely important for raising immune response against bacteria, yeast, fungi, parasites and virus. It is also critical in protecting against cancer, autoimmune disorders like rheumatoid arthritis, allergies etc.
