The glands located on top of each kidney are called adrenal glands. Also known as suprarenal glands, these small, triangular organs produce several crucial hormones that regulate various bodily functions, including blood pressure, immune response, and metabolism.
Adrenal Gland Anatomy and Function
- Location: Situated atop each kidney, one on the left and one on the right.
- Structure: Each adrenal gland consists of two main parts: the adrenal cortex (outer layer) and the adrenal medulla (inner layer). These parts produce different hormones.
- Hormone Production: Key hormones produced include cortisol (regulates metabolism and stress response), aldosterone (controls blood pressure and fluid balance), and adrenaline (involved in the "fight-or-flight" response).
Several sources confirm this information:
- Johns Hopkins Medicine: Their website states that adrenal glands, also known as suprarenal glands, are "small, triangular-shaped glands located on top of both kidneys." https://www.hopkinsmedicine.org/health/conditions-and-diseases/adrenal-glands
- MedlinePlus: This resource clearly states that "Your adrenal glands are two small organs that sit on top of each kidney." https://medlineplus.gov/adrenalglanddisorders.html
- Cleveland Clinic: Their website confirms that adrenal glands are "endocrine glands located on top of your kidneys." https://my.clevelandclinic.org/health/body/23005-adrenal-gland
- Many other sources including the NHS, the Canadian Cancer Society, and the National Institutes of Health, all independently confirm the location of the adrenal glands above the kidneys.
Understanding the adrenal glands' location and function is vital for comprehending various endocrine disorders. Disruptions in their hormone production can lead to a range of health issues.
