Go to the next screen: Note that even though the ascending limb pump can generate a gradient of only 200 mosm/liter at each horizontal level, this effect is multiplied into a large vertical gradient because of the countercurrent flow within the loop. This concentration mechanism is known as countercurrent multiplication. Click the Home Menu Button You have now completed this module Penn 5 AFR ...
