QUESTION
For producing of 1 ml of milk, the quantity of blood which passes through the secretory tissue of mammary gland?
OPTIONS
(A) 400-500 ml
(B) 1000 ml
(C) 200-300 ml
(D) None
ANSWER
(A) 400-500 ml
EXPLANATION
400–500 ml is the correct option because approximately this volume of blood must pass through mammary secretory tissue to provide the nutrients and precursors required to synthesize 1 ml of milk. 1000 ml and 200–300 ml are not the standard physiological estimate, while “None” is incorrect because a recognized approximate blood-flow-to-milk-production relationship exists.
