Question

f the filtration rate described in question #64 persists, which of the following would you expect to occur to restore the normal GFR? 65. I a. afferent arteriole dilates b. efferent arteriole dilates c. afferent arteriole constricts d. proximal convoluted tubule dilates e. nephron loop constricts 66. Alcohol acts as a diuretic because: a. ?l is not reabsorbed by the PCT cells. b. it increases the rate of glomerular filtration. c, it inhibits the secretion of ADH. d. it increases the secretion of aldosterone. e. it constricts the nephron loop 67. Angiotensin II causes which of the following? a. increased thirst b. increased water reabsorption c. increased excretion of potassium d. increased reabsorption of sodium e. all of the above

Explanation / Answer

Answer 63

Diameter of efferent arteriole

Because Constriction of the efferent arteriole increases the blood flow into the glomerulus and which leads to a increases in GFR

Answer 64

Decrease in Nacl concentration

Because when the GFR decreases, Na + is present in the urine will almost be reabsorbed before reaching the macula densa, so the concentration of nacl is decreases

Answer 65

Afferent arteriole dilates

Because their diameter change in order to decrease glomerular hydrostatic pressure (GHP) and restore

Answer 66

It inhibit the secretion of ADH

Because pituitary secretion is inhibited by alcohol and secrete ADH hormone which reabsorb the water from the kidney

Answer 67

All of the above

Because the secretion of the hormone aldosterone from the adrenal cortex.take plave by Angiotensin II
