Structure and Function of the Adrenal Glands Structure and Function of the Adrenal Glands by Jennie Bullock Dogs have two adrenal glands, with one adrenal gland located next to each of the dog's two kidneys.
Adrenal glands are part of a complex hormone production system, known as the endocrine system.
The adrenal gland consists of two parts, the adrenal cortex and the adrenal medulla. Each of these parts serves a different function. The adrenal cortex is the outer part of the adrenal gland. This section secretes many different hormones. The adrenal medulla is the inner part of the adrenal gland.
