ADH and the RAAS both increase water reabsorption, but they respond to different osmoregulatory problems. Which two of the following statements are true?
a. ADH will be released in response to a drop in blood pressure or volume, and the RAAS is most likely to respond following an accident or a severe case of diarrhea.
b. ADH is released when osmoregulatory cells in the hypothalamus detect an increase in blood osmolarity, and the RAAS will decrease blood osmolarity due to the cooperative actions of renin, angiotensin II, and aldosterone.
c. ADH is released when osmoregulatory cells in the hypothalamus detect an increase in blood osmolarity, and the RAAS is a response to a rise in blood pressure or volume.
d. ADH is released when osmoregulatory cells in the hypothalamus detect an increase in blood osmolarity, and the RAAS is most likely to respond following an accident or a severe case of diarrhea.
e. ADH will be released in response to a drop in blood pressure or volume, and the RAAS is a response to a rise in blood pressure or volume
Answer: d. ADH is released when osmoregulatory cells in the hypothalamus detect an increase in blood osmolarity, and the RAAS is most likely to respond following an accident or a severe case of diarrhea.
