  1. reabsorption

    Reabsorption is a biological process that occurs in the kidney where certain substances and water from the filtrate in the tubules are reclaimed back into the bloodstream. It is an essential part of the process of filtering and eliminating waste from the body. In a broader context, reabsorption can also refer to the movement of molecules or substances from an area of lower concentration to an area of higher concentration across a membrane.

Webster Dictionary

  1. Reabsorptionnoun

    the act or process of reabsorbing


  1. Reabsorption

    In physiology, reabsorption or tubular reabsorption is the flow of glomerular filtrate from the proximal tubule of the nephron into the peritubular capillaries, or from the urine into the blood. It is termed "reabsorption" because this is technically the second time that the nutrients in question are being absorbed into the blood, the first time being from the small intestine into the villi. This happens as a result of sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells. Thus, the glomerular filtrate becomes more concentrated, which is one of the steps in forming urine. In this way, many useful solutes, salts and water that have passed in the proximal convoluted tubule through the Bowman's capsule, return in the circulation. These solutes are reabsorbed isotonically, in that the osmotic potential of the fluid leaving the proximal convoluted tubule is the same as that of the initial glomerular filtrate. However, glucose, amino acids, inorganic phosphate, and some other solutes are reabsorbed via secondary active transport through cotransport channels driven by the sodium gradient out of the nephron.
