Detailed explanation-1: -Nephrons filter out harmful substances in the blood so that we can excrete them into the urine. Each nephron is made up of the glomerulus, or a tiny clump of capillaries, where blood filtration begins. These capillaries have very thin walls and they act like a coffee filter.
Detailed explanation-2: -Water reabsorption is a passive process: water is reabsorbed by osmosis. In most of the nephron there is unregulated isosmotic reabsorption of water and solute, in other words, water reabsorption is coupled to solute reabsorption.
Detailed explanation-3: -Answer and Explanation: Most water is reabsorbed from the filtrate in the (a) proximal convoluted tubule. Approximately 70 percent of the total water in the filtrate is reabsorbed in the proximal convoluted tubule through osmosis.
