==Effects of Angiotensin II on Blood Pressure==

'''Angiotensin II''' acts on '''AT1 receptors''' to stimulate the release of '''[[Aldosterone|aldosterone]]''' from the [[Adrenal Glands - Anatomy & Physiology#Adrenal Glands|zona glomerulosa]] of the adrenal glands. This mineralocorticoid increases the excretion of potassium and the reabsorption of sodium, and therefore water and chloride from the distal tubule of the kidney, thus helping to increase blood pressure and volume. It also stimulates the thirst center, and increases the secretion of [[Pituitary Gland - Anatomy & Physiology #Posterior Pituitary Gland |anti-diuretic hormone (ADH)]] to help increase blood volume. The RAAS allows pressure to return to 50% of baseline within 15 minutes of a significant haemorrhage occurring.

It also stimulates the thirst center, and increases the secretion of [[Pituitary Gland - Anatomy & Physiology #Posterior Pituitary Gland |anti-diuretic hormone (ADH)]] to help increase blood volume by making the distal convoluted tubule and the collecting duct permeable to water. The RAAS allows pressure to return to 50% of baseline within 15 minutes of a significant haemorrhage occurring.
