The role of the adrenal glands in the body includes the production of hormones that regulate various physiological functions, particularly in response to stress. These glands, located atop each kidney, secrete hormones such as cortisol, which modulates metabolism and immune response, and adrenaline (epinephrine), which triggers the "fight or flight" response. Additionally, they produce hormones involved in regulating blood pressure and electrolyte balance, like aldosterone. The adrenal glands play a crucial role in the body's complex endocrine system, contributing to maintaining homeostasis during stress and everyday bodily functions.
