Question

Which is not the function of endocrine gland, located in upper dorsal side of heart and aorta?

• A. Plays important role in development of immune system
• B. Induces differentiation of T-lymphocytes
• C. Induces formation of RBCs
• D. Induces development of T-lymphocytes

Answer 1

Answer: (C)

Induces formation of RBCs

Thymus gland is a lobular structure present on dorsal side of heart and aorta. It is associated with the development of immune system. This gland consists of lymphoid tissue which plays an important role in the maturation and proliferation of T-lymphocytes. It secretes thymosin hormone which stimulates differentiation of T-lymphocytes associated with cell-mediated immunity. Thymosin also promotes formation of antibodies for humoral immunity.

RBCs formation is induced by erythropoietin secreted from juxtaglomerular cells of kidney.

So, the correct answer is 'Induces formation of RBCs'.
