Question

In the table given below choose the option in which the source gland, its respective hormone and function are correctly matched.

Source gland	Hormone	Function
(A) Anterior pituitary	Oxytocin	Contraction of uterus muscles during child birth
(B) Posterior pituitary	Vasopressin	Stimulates resorption of water in the distal tubules in the nephron
(C) Corpus luteum	Oestrogen	Supports pregnancy
(D) Thyroid	Thyroxine	Regulates blood calcium level

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer: (B)

B

Anterior pituitary secretes growth hormone (GH), thyroid stimulating hormone (TSH), adrenocorticotrophic hormone (ACTH), luteinising hormone (LH), follicle stimulating hormone (FSH) and prolactin. Posterior pituitary releases Anti-diuretic hormone (ADH) also knowns as vasopressin. This hormone helps the kidneys to increase water absorption. The corpus luteum secretes progesterone which supports the pregnancy. Thyroid secretes thyroxine which helps in the regulation of body's metabolic rate, heart and digestive functions. Oxytocin is also stored and released from posterior pituitary and plays a role in the uterine contraction during labour.

So, the correct answer is option B.
