    omg so did I lol. I woke up at 3 am and for some reason asked myself do gills separate the oxygen from hydrogen? couldn't get back to sleep till I found out. writing this now I realize if you have a fish tank and don't circulate the water, putting more o2 in, the fish will suffocate despite there being of water. I'm 28 and it took me 2 hours to realize that smh.

    One thing I don't quite get here. I don't see why the examples are that different with regards to the "final product". They are both resulting in 20ppm of oxygen diffusing into the vessels of the gills. With the concurrent flow surely diffusion is initially faster then slows as equilibrium is met compared with the slow and steady counter current system.

    The blood and water don't mix. The blood stays in the capillaries and absorbs oxygen from the water through the walls of the capillaries. It's a bit like the engine cooling system in your car radiator.

    I still don't understand why the water has only 80ppm O2 before the counter current blood even reached the water. Shouldn't the water still have 100ppm O2 before the blood came? Where did the 20ppm O2 go, when there was no contact with the blood before? I am not sure if someone understands what I mean. But if somebody does, I would appreciate an explanation.
