List three characteristics of all veins.
Have valves that serve to maintain a unidirectional flow of blood, carry blood toward the heart, have thinner walls than arteries.

5.    The source of trypsin and chymotrypsin is the ________________.

Pancreas
500
Explain a mechanism by which antidiuretic hormone (ADH) regulates blood osmolarity. What type of feedback circuit is involved?
Blood osmolarity increases as a consequence of sweating. Osmoreceptors in the hypothalamus detect the increase in blood osmolarity and release ADH. ADH acts upon the collecting ducts to increase the number of aquaporin channels. The aquaporins enhance reabsorption of water from the collecting ducts reducing blood osmolarity. Negative Feedback
