WebIn this review, the emerging functional roles of the brain angiotensin system have been considered. The major effects of Ang II can be classified into three groups, which imply three possible functions: The first, and largest, group is actions associated with the regulation of body fluid volume in response to hypovolemia. WebAngiotensin II also triggers the release of the hormone aldosterone from the adrenal glands and vasopressin (antidiuretic hormone) from the pituitary gland. Aldosterone and vasopressin cause the kidneys to retain sodium (salt). Aldosterone also causes the kidneys to excrete potassium. The increased sodium causes water to be retained, thus ... dallas boxing classes
