WebEffects of ANP on the Cortical Collecting Duct. Water reabsorption takes place in the cortical collecting duct (CCD) cells, induced by the peptide hormone vasopressin. An increase in 3’5’-cyclic adenosine monophosphate (cAMP) levels in these cells leads to an increasing permeability of the CCD apical membrane to water.

"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. " - Does anp increase water reabsorption

The correlation with Na+ and water reabsorption is so strong that the fluid in the lumen of the proximal tubule remains essentially isosmotic, despite the massive reabsorption or solutes and water.

WebADH (Antidiuretic Hormone) The brain and kidneys regulate the amount of water excreted by the body. When the blood volume is low, the concentration of solutes in the blood is high. When the hypothalamus senses this low blood volume and increased serum osmolality it synthesizes ADH, a small peptide molecule. The pituitary gland then releases ADH ... WebThe distal nephron is able to fine-tune sodium and water balance because it can regulate reabsorption of sodium and water independently of each other.
