Adrenal glands

The adrenal glands are two small triangle-shaped glands. One gland is located on top of each kidney.

Endocrine glands

Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the rate of metabolism in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).

Adrenal glands

Triangular-shaped glands located on top of the kidneys. They produce steroid hormones such as aldosterone, cortisol, and precursor sex steroids that can be converted into estrogen and testosterone. They also produce the hormones adrenalin (epinephrine) and noradrenalin (norepinephrine).

Adrenal gland biopsy

The adrenal glands are endocrine glands which are located immediately on top of the kidneys. During an adrenal biopsy, a small sample of tissue is removed and sent to the pathologist for testing. The biopsy can be performed when a suspicious mass or tumor is found on one or both of the adrenal glands.
