Which of the following glands secretes mineralocorticoids? Adrenal cortex Adrenal medulla Posterior pituitary Anterior pituitary

The **adrenal cortex** is responsible for secreting mineralocorticoids, with **aldosterone** being the primary mineralocorticoid produced. Mineralocorticoids play a crucial role in regulating electrolyte and water balance by influencing sodium and potassium levels in the body, thereby affecting blood pressure. Here's a brief overview of the options: 1. **Adrenal Cortex**: Produces mineralocorticoids (e.g., aldosterone), glucocorticoids (e.g., cortisol), and androgens. 2. **Adrenal Medulla**: Secretes catecholamines like epinephrine and norepinephrine. 3. **Posterior Pituitary**: Releases hormones such as vasopressin (ADH) and oxytocin. 4. **Anterior Pituitary**: Produces a variety of hormones including ACTH, TSH, GH, and others, but not mineralocorticoids. **Answer:** Adrenal cortex
