Column I	Column II
A. ANF	(i) Regulates blood calcium levels
B. MSH	(ii) Decreases blood pressure
C. GIP	(iii) Pigmentation
D. CT	(iv) Inhibits gastric secretion

• A. A-(iv), B-(i), C-(ii), D-(iii)
• B. A-(ii), B-(i), C-(iv), D-(iii)
• C. A-(iv), B-(i), C-(iii), D-(ii)
• D. A-(ii), B-(iii), C-(iv), D-(i)

Answer 1

The correct option is D A-(ii), B-(iii), C-(iv), D-(i)

A. ANF: The cells, called cardiocytes, of the atria secrete a peptide, atrial natriuretic factor( ANF) in response to an increased return of the venous blood. This hormones regulates the blood volume through increased excretion of ions and water.

B. MSH: It is secreted by intermediate lobe of pituitary called melanocyte stimulating hormone. It stimulates the synthesis of black pigment melanin in the skin.

C. GIP: It is secreted by duodenal mucosa. It shows gastric contractions and stops the secretion of gastric juice. It is called as gastric inhibitory peptide or enterogastrone.

D. CT: It is calcitonin secreted by thyroid. It regulates blood calcium levels.

So, the correct answer is 'A-(ii), B-(iii), C-(iv), D-(i)'.
