How does urea enter the kidney?
Urea is carried in the bloodstream to the kidneys. The kidneys are bean-shaped organs about the size of your fists. They are near the middle of the back, just below the rib cage. The kidneys remove urea from the blood through tiny filtering units called nephrons.
Which part of nephron is permeable to urea?
The thick ascending limb of the loop of Henle is permeable to urea (and sodium) but not to water. Movement of urea down its concentration gradient into the interstitium contributes significantly to medullary hypertonicity; the inner medullary portion of the collecting duct (see below) is also permeable to urea.
What is the most permeable part of the nephron?
The descending portion of the loop of Henle is extremely permeable to water and is less permeable to ions, therefore water is easily reabsorbed here and solutes are not readily reabsorbed.
