Vasoconstriction: Angiotensin II causes the constriction of blood vessels, increasing blood pressure. Aldosterone Secretion: It stimulates the adrenal cortex to produce aldosterone, which increases sodium and water reabsorption in the kidneys. Cell Growth: It promotes cell proliferation and hypertrophy, especially in vascular smooth muscle cells. Sympathetic Activation: It enhances the release of norepinephrine from sympathetic nerve endings.
