WebADH tavels to the collecting tubules in the kidneys and makes the membrane more permeable to water (that is it increases water reabsorption) which leads to a decrease in urine output. b. ADH also travels to the sweat glands where it stimulates them to decrease perspiration to conserve water. WebIt regulates your blood pressure by increasing sodium (salt) reabsorption, water reabsorption (retention) and vascular tone (the degree to which your blood vessels constrict, or narrow). The RAAS consists of three major substances, including: Renin (an enzyme). Angiotensin II (a hormone). Aldosterone (a hormone).

The Renin-Angiotensin-Aldosterone-System

WebANP affects salt release, and because water passively follows salt to maintain osmotic balance, it also has a diuretic effect. ANP also prevents sodium reabsorption by the renal tubules, decreasing water reabsorption (thus acting as a diuretic) and lowering blood pressure. Its actions suppress the actions of aldosterone, ADH, and renin. Webreabsorption increases. Because aldosterone is also acting to increase sodium reabsorption, the net effect is retention of fluid that is roughly the same osmolarity as bodily fluids. The net effect on urine excretion is a decrease in the amount of urine excreted, with lower osmolarity than in the previous example. grammis award for hard rock/metal of the year
