Zona Glomerulosa

The zona glomerulosa is the outermost layer of the adrenal gland, a small organ on top of your kidneys. It mainly produces a hormone called aldosterone, which helps regulate blood pressure and balance of salt and water in your body. Aldosterone signals your kidneys to retain sodium and water, and excrete potassium, which maintains healthy blood pressure and fluid levels. This layer's function is essential for keeping your body's internal environment stable. The zona glomerulosa responds to signals like blood pressure and potassium levels to adjust aldosterone production accordingly.
