Adrenal hormones play a crucial role in regulating various physiological processes in the body. The adrenal glands, located on top of the kidneys, produce a group of hormones known as steroid hormones. These hormones are synthesized in the adrenal cortex, which consists of three distinct layers: the zona glomerulosa, zona fasciculata, and zona reticularis. Zona Glomerulosa: Electrolyte Balance Regulator The zona glomerulosa is the outermost layer of the adrenal cortex. Its primary function is to produce mineralocorticoids, with aldosterone being the major hormone. Aldosterone plays a vital role in regulating electrolyte balance by promoting sodium reabsorption and potassium excretion in the kidneys. It helps maintain blood pressure, fluid volume, and electrolyte concentrations within the body. Zona Fasciculata: Metabolism and Stress Response The zona fasciculata, located in the middle layer of the adrenal cortex, is responsible for synthesizing glucocorticoids, predominantly cortisol. ...
