The adrenal gland is part of the endocrine system and produces hormones that are essential for survival. The adrenal cortex, the largest part of the adrenal gland, produces three major hormones. Glucocorticoids regulate metabolism of glucose, protein, and fat and allow the body to respond to stress by increasing blood glucose levels and cardiac output. Mineralocorticoids regulate fluid and electrolyte balance and help maintain blood pressure.
Androgens are responsible for sexual differentiation in the fetus.
