NEET BIOLOGY

Detailed explanation-1: -The distal convoluted tubule and collecting ducts are then largely responsible for reabsorbing water as required to produce urine at a concentration that maintains body fluid homeostasis.

Detailed explanation-2: -The Role of Aquaporins in the Kidneys The majority of water reabsorption that occurs in the nephron is facilitated by the AQPs. Most of the fluid that is filtered at the glomerulus is then reabsorbed in the proximal tubule and the descending limb of the loop of Henle.

Detailed explanation-3: -Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic about 5.6   6.9.

Detailed explanation-4: -Option A: The ascending limb of the loop of Henle is only responsible for minimum reabsorption of water and electrolyte is not reabsorbed in this part.

Detailed explanation-5: -From Bowman’s capsule the tubular fluid flows towards the proximal tubule, which remains in the outer layer (cortex) of the kidney. The proximal tubule is the major site of reabsorption of water and solutes in equal proportions from the filtered tubular fluid.
