Question

Write the role of tubular part of nephron in urine formation.

Answer 1

The tubular component of the nephron, including the renal tubule, is responsible for urine production through many processes:

1. Filtration: The glomerulus allows blood to enter the nephron, which is filtered to remove water, ions, and tiny molecules before entering Bowman's capsule.
2. Reabsorption: To maintain physical balance, the renal tubule reabsorbs vital elements such as glucose, water, and ions into the bloodstream.
3. Secretion: The kidneys actively produce excess ions and waste materials from the blood into the tubules.
4. Concentration: Urine is the remaining fluid in the collecting duct before being excreted in the kidneys.
