Explain Selective reabsorption
Advertisements
उत्तर १
Selective reabsorption:
The glomerular filtrate entering the renal tubule contains many useful substances. Hence, as the filtrate passes down the tubule, water and other substances required by the body are reabsorbed. This reabsorption occurs only to the extent that the normal concentration of the blood is undisturbed. This entire process is called selective reabsorption.
