Countercurrent Exchange
In countercurrent multiplication, we saw how water and Na+ were reabsorbed into the interstitium in the Loop of Henle. Where do the reabsorbed substances go? How do they join back the systemic circulation? Watch the video to learn about countercurrent exchange, the mechanism that puts those substances back in the circulation.

SOLVED:The countercurrent exchange mechanism in fish gills a. maximizes oxygen diffusion into the bloodstream. b. is a less efficient mechanism for gas exchange than that used in mammalian lungs. c. occurs because the flow of blood is in the same direction as water flowing across the gills. d. facilitates diffusion of CO2 into the blood of fishes. e. facilitates diffusion of oxygen into the environment.
