The adrenal glands are small, triangular-shaped organs located on top of each kidney. They play a crucial role in producing hormones that help regulate various bodily functions, including metabolism, immune response, and stress management. The two main parts of the adrenal glands are the cortex, which produces hormones like cortisol and aldosterone, and the medulla, which produces adrenaline and noradrenaline. These hormones are essential for maintaining balance in the body. For example, when you face a stressful situation, the adrenal glands release adrenaline, which prepares your body for a quick response. This is often referred to as the "fight or flight" response, helping you react to challenges effectively.
