What is the function of adrenal glands?

The adrenal glands produce hormones that help the body respond to stress, regulate metabolism, maintain blood pressure, and control salt-water balance. These glands play an important role in helping the body function during both normal and emergency situations.

The adrenal glands are located above the kidneys.
