Functions of Renal Tubule: The renal tubule of which the kidney is for the most part made up, is a long and convoluted structure that emerges from the glomerulus. It can be divided into three parts based on function.
- The first part is the proximal convoluted tubule (PCT) due to its proximity to the glomerulus and it stays in the renal cortex.
- The second part is the Henle’s Loop or nephritic loop as it forms a loop (with descending and ascending limbs) that goes through the renal medulla.
- The third part of the renal tubule is the distal convoluted tubule (DCT). This part is restricted to the renal cortex.
Functions of Renal Tubule
- The first segment of the renal tubule is involved in the reabsorption of solutes that play an essential role in maintaining proper bodily functions.
- Reabsorption of solutes such as amino acids, glucose, and salts, takes place.
- This reabsorption might be active, as in the case of glucose, amino acids, and peptides, or passive, as in the case of water, chloride, and other ions.
