What is the adrenal gland?
The adrenal glands are a set of paired glands found within the abdomen in cats and dogs that constitute a major portion of the hormonal (endocrine) system. The adrenal gland can be split into two major regions. The outer portion, the cortex, is responsible for producing cortisol (the main stress hormone of the body), some sex hormones, and substances which help regulate the body’s blood pressure and electrolyte balance. The inner portion, the medulla, produces adrenaline and its precursors (epinephrine, norepinephrine). The adrenal glands are located very near the kidneys and adjacent to the major blood vessels of the abdomen, the aorta and caudal vena cava.
