WebCocurrent gas exchange 2.) Countercurrent gas exchange. 1.) Referring to two fluids flowing in the same direction. 2.) Exchange of heat, O2, or other substances by passive transport processes (e.g. diffusion) between two closely juxtaposed fluid streams flowing in opposite directions (e.g blood flowing in opposite directions in two blood vessels). Webbiology-countercurrent. Counter current gas exchange (gills) Gills are very efficient at taking out what little oxygen is present in the water. This efficiency stems from an adaptation known as countercurrent exchange. Counter current involves blood in the capillaries flowing in the opposite direction to the flow of water flowing over them.
