Explanation / Answer

Ans 1:- (c) Hypothalamus.

Explaination:- The hormone ADH is synthesized by the neurons in the supraoptic nucleus in the hypothalamus after their syntheis ADH is transported down the axons of the neurons in the posterior pitutary.

Ans 2:- (b) decreased respirations.

Explaination:- decreased ventillation (decreased respiration) increases the concentration of carbon dioxide in the blood and hence blood pH decreases a condition called acidosis.

Ans 3:- (d) All of the above.

Explaination:- More viscosity means slow movement hence impact the flow, increase in length has the same effect similarly if blood vessel has large radius then the flow is fast.
