Adrenal glands are endocrine organs that secrete hormones into the bloodstream. The adrenal cortex is the outer part of the glands, which secretes steroid hormones, including mineralocorticoids. Learn about the main mineralocorticoid - aldosterone, the role that aldosterone plays in the renin-angiotensin system, and how aldosterone regulates sodium, potassium and blood pressure in the body.
