From which gland is cortisol released?

Cortisol is a steroid hormone produced by the adrenal cortex, which is the outer layer of the adrenal glands located on top of each kidney. The adrenal cortex is responsible for synthesizing and releasing various hormones, including cortisol, which plays a vital role in regulating metabolism, the immune response, and stress response. When the body experiences stress, the hypothalamus signals the adrenal cortex to release cortisol, which helps to mobilize energy and manage bodily functions in response to stressors. Understanding the role of the adrenal cortex in hormone production is crucial for comprehending how the endocrine system functions and maintains homeostasis.
