GENERAL HISTOLOGY

Detailed explanation-1: –The proximal convoluted tubule reabsorbs all of the glucose in the blood through ion cotransport.-The loop of Henle (also known as the nephron loop) is a U-shaped tube with descending and ascending limbs that vary in permeability.

Detailed explanation-2: -Most of the glucose entering the tubular system is reabsorbed along the nephron segments, primarily in the proximal tubule, such that urine is almost free of glucose.

Detailed explanation-3: -Almost all of the glucose, lactate, and amino acids, and most of the phosphate and citrate that’s filtered by the glomerulus is reabsorbed with the help of sodium in the proximal convoluted tubule.

Detailed explanation-4: -The proximal tubule also completes the reabsorption of glucose, amino acids, and important anions, including phosphate and citrate, because it is the sole site of transport of these filtered solutes.
