Describe the function of major hormones (steroid hormones, epinephrine, insulin & glucagon) and major endocrine glands (hypothalamus, pituitary, adrenal glands, pancreas) and how they regulate metabolism.

Compare the osmotic problem and the mechanism of osmotic regula-tion in freshwater and marine bony fishes.

If plasma osmolarity increases to 380 mOsM, what would likely happen to the plasma concentrations of ADH and the reabsorption of water from the kidneys?   a. Plasma ADH concentrations decrease; reabsorption of water decreases b. Plasma ADH concentrations increase; reabsorption of water decreases c. Plasma ADH concentrations increase; reabsorption of water does not change d. Plasma ADH concentrations increase; reabsorption of water increases e. Plasma ADH concentrations decrease; reabsorption of water increases
