WebSelective reabsorption involves the reuptake of useful substances from the filtrate and occurs in the convoluted tubules (proximal and distal). The tubular epithelial cells in different segments of nephron perform this either by active or passive mechanisms. The majority of selective reabsorption occurs in the proximal convoluted tubule, which ... WebMay 24, 2012 · During reabsorption, necessary nutrients in the glomerular filtrate are reabsorbed back to the blood from the rest of the parts of the nephron. Unlike filtration, reabsorption is selective. Thus, this is a summary of the difference between filtration and reabsorption. Reference: 1. “Nephron – Definition, Function and Structure.”

WebScore: 4.4/5 (33 votes) . Selective reabsorption is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron. WebKidney Reabsorption. Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: Specialized proteins called transporters are located on the membranes of the various cells of the nephron. These transporters grab the small molecules from the filtrate as it flows by them.
