describe why the loop of Henle is a loop, not a straight line include what substances can leave what sections and the effects that has on both water and salt reabsorption?

Answer

  • The loop of Henle facilitate formation of concentration gradient by establishment of countercurrent multiplier.
  • There are two segments of loop of Henle.
  • Ascending limb of loop of Henle is permeable to NaCl but is impermeable to water. As a result NaCl diffuses out in the interstitial fluid.
  • Interstital fluid becomes much concentrated and creates a gradient to reabsorb water from descending limb. The descending limb of loop of Henle is permable to water but not to NaCl.
  • Also, as interstitial fluid has more NaCl concentration than in the fluid entering collecting duct, water diffuses from collecting duct into the interstitum.
  • This helps in concentrating the urine.


Also, as terminal part of collecting duct is permeable to urea, it is reabsorbed and enters interstitium.

Hence, urea also contributes to increase insterstitial osmolarity aiding water reabsorbtion.


Hence, loop of Henle is a loop and not a straight line.
