Near the cortex

Vedclass · Answer

(A) The osmolarity of the kidney tissue near the cortex is approximately $200-300 \; mOsmL^{-1}$.As we move deeper into the medulla,the osmolarity increases significantly,reaching up to $1200 \; mOsmL^{-1}$ near the inner medulla.Since the concentration of $Na^+$ and $Cl^-$ ions is directly proportional to the osmolarity of the interstitial fluid,their concentration is lowest in the cortical region.

The concentration of sodium and chloride ions is lowest in which of the following regions?
