The percentage of water reabsorbed into the blood after filtration out of the blood in the renal corpuscles of the kidney is 99%. In tubular reabsorption, the percentage of 1% of the glomerular filtrate actually leaves because the 99% is reabsorbed into the blood when it passes in the renal tubules and ducts. This process is tubular reabsorption and occurs in three mechanisms which are osmosis, diffusion and active transport. The body’s needs are the basis why reabsorption varies as per individual. This enables the body to retain most of its nutrients. This happens when solutes and water are removed from the tubular fluid and transported into the blood.
