Answer 1

ANSWER :

19) When oxygen demand in peripheral tissue is high but respiratory minute volume of air remains same that might be due to low alveolar partial pressure of CO2 and vasoconstriction of blood vessels.

20) During respiratory acidosis, body's autonomic or homeostatic system compensate with changes in the physiology to get rid of this condition. In this process carbonic acid dissociates into H+ & bicarbonate ions, H+ ions excrete out through kidney and bicarbonates reserved in the body cells to maintain pH. Respiratory rate will also increase to high level for removing excess CO2.

30) The secretion acid (HCl) and gastric enzymes from mucosa of stomach regulated via release of local digestive tract hormone (gastrin).

31) Afferent arteriole arrives to the glomerular capsule and before it leaves the kidney it runs parallel to the ascending loop of Henle's.
