Answer #1

41. Increase respiratory rate.

Decrease on blood ph seen in that case.so rate and depth of breathing increases.

42. There is increased unloading of tissue.

Because highhamount of oxyhemoglobin present in arterial blood.

43.the active resorption of Na+ from ascending loop of henle

Ascending loop impermeable to water, descending loop impermeable to sodium

44.increases urine output

It prevent water congestion

45.erythropoietin

Calcitrol,erythopoietine, renin secreted by kidney

46.active absorption of sodium ion.
