Nephron tube where nutrients are reabsorbed?

Answer 1

The Nephron is the functional unit of the Kidney which regulates blood contents NOT urine contents. It works by filtering out much of the contents of the blood from the Glomerulus into Bowmans Capsule. From here the a long tubule projects and is followed by a blood vessel (the Efferent Capillary) which reabsorbs much of the nutriens, what isn't reabsorbed goes into the Urine via a Collecting Duct. There are three parts to the nephron, the Proximal Convoluted Tubule, the Loop of Henle and the Distal Convoluted Tubule. The loop of Henle is mostly involved in the reabsorbtion of water with the use of salts. The majority of nutrients reabsorbtion takes place is the proximal convoluted tubule. It should be noted that although the nephron is very efficient (it reabsorbs 90% of the water if need be) it also reabsorbs about 50% of the urea so it is incorrect to think that it all goes straight into the urine. In short, to answer you question, most nutrients are reabsorbed in the Proximal Convoluted Tubule.
