Passive reabsorption in kidney

WebReabsorption in the DCT is under hormonal control. The active reabsorption of Na+ from the tubular fluid into peritubular capillaries is promoted by the hormone aldosterone. Passive reabsorption of negative ions, such as Cl – and HCO 3 –, then occurs by electrochemical attraction. The reabsorption of ions decreases the osmotic pressure of ...

WebReabsorption occurs mostly in the nephron's proximal convoluted tubule. The renal tubules reintroduce nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration. The body also reabsorbs sodium to maintain fluid balance. Water enters the kidney through the glomerulus and leaves via the urine. WebA 22-year-old man was admitted with complaints of dyspnea and hoarseness.
