what are proximal tubules?Explain their predominant role in kidneys?

Posted by Aryan Pathak 4 years, 11 months ago

CBSE > Class 10 > Science

1 answers

Sia ? 4 years, 11 months ago

The proximal tubule efficiently regulates the pH of the filtrate by exchanging hydrogen ions in the interstitium for bicarbonate ions in the filtrate; it is also responsible for secreting organic acids, such as creatinine and other bases, into the filtrate.
The proximal tubule is responsible for the reabsorption of ~ 60% of previously filtered potassium. Solvent drag and diffusion have been proposed as the major driving forces of this process, and K⁺ is reabsorbed largely via the paracellular pathway.

Fragmentation:- ~In multi-cellular organisms,with simple body organization this occurs.~ Spirogyra breaks up into small pieces upon maturation. These fragments grow into new individuals.
