Distinguish between exocrine and endocrine glands
What will be an ideal response?
ANSWER: Exocrine glands remain connected to epithelium by a duct. Examples of exocrine
secretions include mucus, saliva and sweat. Endocrine glands are not connected to
epithelium by a duct. They become suspended in connective tissue underlying the
epithelium. They release hormones directly into the interstitial fluid, which are then passed
into the blood to be distributed by the circulatory system. Examples include the pituitary
gland and thyroid gland.

Vasopressin is a hormone that is primarily released when the body is low on water. Release of vasopressin causes the kidneys to conserve water by concentrating urine and decreasing urine output. However, vasopressin also has additional functions in other tissues such as the brain and blood vessels, which are not directly involved in urine production. How could it be possible for vasopressin to trigger different responses in different tissues?
A. Vasopressin binds to the same exact receptor in different tissues, but causes a different conformational change to the receptor in each tissue. B. The kidneys have a receptor for vasopressin, but cells in the brain and blood vessels do not have a receptor for vasopressin. C. Vasopressin can bind to, and act on, different receptor subtypes, leading to different cellular responses in different tissues. D. Vasopressin can be released at different times to result in different effects.
