A)  The kidneys are the most important mechanism for eliminating all bicarbonate ions.
B)  The kidneys are not able to excrete phosphoric acid.
C)  Excreted hydrogen ions are unbound in the filtrate.

Accepted Answer

A)  excess water in interstitial spaces due to a low level of plasma proteins
B)  hypotonic hydration,in which sodium content is normal but water content is high
C)  excessive hydration due to excess ADH secretion

F) B) and C)

Question 18

Describe the influence of rising PTH levels on bone,the small intestine,and the kidneys.

Accepted Answer

Parathyroid hormone PTH)activates osteoclasts that break down the bone matrix,resulting in the release of Ca2+ and PO43- to the blood.PTH enhances intestinal absorption of Ca2+ indirectly by stimulating the kidneys to transform vitamin D to its active form,which is necessary for calcium absorption by the small intestine.PTH increases the reabsorption of calcium by the renal tubules,which simultaneously decreases phosphate ion reabsorption.

F) B) and C)

Question 20

What hormone reduces blood pressure and blood volume by inhibiting nearly all events that promote vasoconstriction and sodium ion and water retention?

Accepted Answer

A)  thyroxine
B)  ADH
C)  aldosterone
D)  atrial natriuretic peptideE) A) and B)
F) C) and D)
