Under stress, the body releases cortisol from the adrenal gland in order to:
a. stimulate renal excretion of sodium to cause potassium levels to increase.
b. break down body protein to increase amino acids that can be converted to glucose.
c. cause vasoconstriction to divert blood flow from the periphery to central circulation.
d. increase heart and respiratory rates to better deliver oxygen and nutrients to vital organs.
Question 2
Secretion of endogenous catecholamines cause the following responses:
a. increased heart rate, decreased blood pressure, increased respiration rate.
b. increased heart rate, increased basal metabolic rate, increased blood pressure.
c. decreased basal metabolic rate, increased oxygen consumption, decreased heart rate.
d. increased secretion glucagon, decreased cardiac contractility, decreased peripheral perfusion.
