The suprarenal glands, also known as adrenal glands, belong to the endocrine system. They are a pair of triangular-shaped glands, each about 2 in long and 1 in wide, that sit on top of the kidneys (see the image below).
The adrenal glands are located just above the kidneys. The adrenal gland consists of 2 parts. The outer portion, called the cortex, produces cortisol. This is an important hormone for controlling blood pressure. The inner portion, called the medulla, produces the hormone adrenaline (also called epinephrine).
