What would lead to an increase of antidiuretic hormone (ADH)?
abnormally high blood pressure
drinking a large volume of pure water
sweating-induced dehydration
eating a small sugary snack
Which of the following combinations would lead to the greatest INCREASE in blood pressure?
decrease ADH and decrease aldosterone
decrease ADH and increase aldosterone
increase ADH and decrease aldosterone
increase ADH and increase aldosterone
The hormone which has the opposite effect of aldosterone is:
O ANF which decreases Na+ reabsorption in the proximal tubule
ANF which increases Na+ reabsorption in the proximal tubule
ANF which increases Na+ reabsorption in the distal tubule
ANF which decreases Na+ reabsorption in the distal tubule

- are both statements correct? Renin converts angiotensinogen to angiotensin I, which is then converted to angiotensin II by angiotensin-converting enzyme. Angiotensin II stimulates aldosterone secretion, and aldosterone decreases the rate of Na+ and Cl− reabsorption from the nephron. Atrial natriuretic hormone, secreted from the right atrium in response to decrease in blood pressure, acts on the kidney to decrease Na+ in the urine.arrow_forwardAfter drinking alcoholic beverages, a hangover with headache and nausea is common.
