Question

Which of the following acts as both an endocrine and an exocrine gland?

a. kidney

b. pancreas

c. gall bladder

d. liver

Answer 1

It's A.  The kidney is involved in the exocrine system because it filters the blood before the wastes are excreted as urine.  The adrenal glands are also located on top of the kidney and are involved in the endocrine system.  Their main function is to secrete the ADH hormone.  This controls how much water the body should retain and how much should be excreted with the urine.

Answer 2

I think it is B. B is the only organ listed that is an endocrine gland. There is a gland, the adrenal gland on top of the kidneys, but the kidneys themselves are not glands.
