THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -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. In addition to solute reabsorption and secretion, the proximal tubule is also a metabolic organ.

Detailed explanation-2: -Proximal tubules are responsible for reabsorbing approximately 65% of filtered load and most, if not all, of filtered amino acids, glucose, solutes, and low molecular weight proteins. Proximal tubules also play a key role in regulating acid-base balance by reabsorbing approximately 80% of filtered bicarbonate.

Detailed explanation-3: -Reabsorption takes place in the ‘kidney tubule or nephron’. Different parts of the kidney tubule such as proximal & distal convoluted tubules, Henle’s loop, and collecting duct play a major role in reabsorption. Most of the reabsorption takes place in proximal convoluted tubules (PCT).
