WebThe process of urine formation in the kidneys occurs in two stages Ultrafiltration Selective reabsorption Ultrafiltration involves filtering small molecules from the blood at high pressure This occurs between the glomerulus and the bowman's capsule Selective reabsorption allows the kidney to reabsorb useful small molecules into the blood WebFirst coiled (convoluted) tubule: the liquid which enters this first tubule is known as the glomerular filtrate. The first tubule is where much of the reabsorption takes place. All of the glucose is actively taken back into the blood along with around 67% of the sodium ions and around 80% of the water. It has many microvillus to increase the ... khombu winter boots on sale

Absorption The proximal tubule efficiently regulates the pH of the filtrate by secreting hydrogen ions (acid) into the tubule and reabsorbing approximately 80% of the filtered bicarbonate. Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. This is driven by … See more The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle.
