Final answer:
The adrenal glands are located on top of the kidneys and consist of an outer adrenal cortex and an inner adrenal medulla. The adrenal cortex synthesizes and releases steroid hormones, while the adrenal medulla produces and releases adrenaline and noradrenaline.
Step-by-step explanation:
The adrenal glands are located on top of each kidney. They consist of an outer adrenal cortex and an inner adrenal medulla. The adrenal cortex synthesizes and releases steroid hormones such as cortisol and aldosterone, which regulate important bodily processes like metabolism and blood pressure. On the other hand, the adrenal medulla produces and releases adrenaline and noradrenaline, which help the body respond to stress.
