Cortisol5
- Cortisol and corticosterone, both corticosteroids, and the hormone aldosterone are secreted from the adrenal cortex directly into the bloodstream. (vitalitymagazine.com)
- The adrenal cortex produces 3 steroid hormones: glucocorticoids (cortisol), mineralocorticoids (aldosterone, 11-deoxycorticosterone), and androgens (dehydroepiandrosterone). (medscape.com)
- Finally, cortisol facilitates free-water clearance, enhances appetite, and suppresses adrenocorticotropic hormone (ACTH) synthesis. (medscape.com)

(bvsalud.org)
ACTH5
- When the pituitary gland receives a high stress signal, the adrenocorticotropin hormone (ACTH) is released into the bloodstream, stimulating the liver to provide the body with stored carbohydrates which in turn provide extra energy and increase muscle tension, blood pressure, heartbeat, respiration.
