What is the function of zona glomerulosa?

The zona glomerulosa is the outermost layer of the adrenal cortex, primarily responsible for the production of mineralocorticoids, with aldosterone being the most significant hormone it secretes. Aldosterone plays a crucial role in regulating electrolyte balance and blood pressure by promoting sodium retention and potassium excretion in the kidneys. This helps maintain fluid balance and overall homeostasis in the body.
