Question

Question 1 (1 point) All of the following statements about bicarbonate ions are true EXCEPT: bicarbonate ions are excreted in the urine in proportion to hydrogen ion excretion. the kidneys are capable of synthesizing new bicarbonate ions. O the kidneys can reabsorb bicarbonate ions. O bicarbonate ions act in a chemical buffer system as a weak base. there is many more bicarbonate ions than carbonic acid molecules in the carbonic acid-bicarbonate buffer system. Question 2 (1 point) Which of these results in an increase blood Na+ concentration? decrease in ADH secretion O increase in aldosterone secretion O increase in ANP O decrease in renin secretion Question 3 (1 point) In an attempt to compensate for plasma acidosis: O Breathing rate and depth will increase O Breathing rate and depth will decrease O Breathing rate will increase and depth will decrease Breathing rate and depth will not change since only the renal mechanism can deal with acidosis

Answer 1

UQ Bicaibonate Ions are excited in the viene in proportion to hydrogen ion excretion This is not true. AS bicarbonate ions are reabsorbed by the Ridney, these are aveak base that help in regulating the pH of body. - B toue, kidney can synthesize as play vuole in acid base balance Reabsorb, act as buffer, more bicarbonate than carbonic aud. So B,C,D,& are correct , A is not true. Scanned with CamScanner

Increase blood Nat conc. result due to increase in aldosterone secretion. As aldosterone help in Nat Retention Option B correct. Scanned with CamScanner TYTTIST Tootwory
