Proportion of Filtered Substances Reabsorbed in the Proximal Tubule Substance % of Filtrate Reabsorbed Sodium and Water ~66% Organic solutes e.g. glucose and amino acids ~100% Potassium ~65% Urea ~50% Click to see full answer. Moreover, what is reabsorbed in the kidney?In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood. The kidneys sense low blood pressure. Release renin into the blood.One may also ask, how is sodium reabsorbed in the kidney? Sodium passes along an electrochemical gradient (passive transport) from the lumen into the tubular cell, together with water and chloride which also diffuse passively. Water is reabsorbed to the same degree, resulting in the concentration in the end of the proximal tubule being the same as in the beginning. Accordingly, which of the following substances is reabsorbed by the kidneys? Learning Objectives Substances Secreted or Reabsorbed in the Nephron and Their Locations (Table 5) Substance PCT Collecting ducts Lactate Reabsorbed Creatinine Secreted Urea 50 percent reabsorbed by diffusion; also secreted Reabsorption in medullary collecting ducts; diffusion What mineral Cannot be reabsorbed by the kidney?Urine. Urine contains water, urea and mineral ions. Urea is produced in the liver when excess amino acids are broken down. Urea is the main waste product removed in the urine, as it is not reabsorbed in the kidney.
