The primary function of the adrenal glands is to produce and release hormones that regulate various body functions. These glands, situated atop the kidneys, secrete hormones like cortisol, which helps manage stress and metabolism, and adrenaline, which prepares the body for a ‘fight or flight’ response. They also produce sex hormones and contribute to metabolism regulation, fluid and electrolyte balance, and the overall maintenance of homeostasis.
