Functions of Renal Tubule – Class 11 | Chapter – 19 | Biology Short Notes Series PDF

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.

Renal Tubule

  • 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.
