Explain how the counter current system works.
We have seen this system in the gills of fish, the blood in extremities, and the tubules of the kidneys.

Explain how the system works and site these specific examples above indicating what the system is doing in that particular organ.
Answer:
Counter current mechanism is a system of functioning that occurs in nature, wherein there is a crossover of two bodies that move in opposite directions. The moving bodies can be heat, gas, water or blood. This counter current mechanism is mimicked by industries to procure the desired results artificially. Counter current mechanism is often seen in the gills of fish, kidneys and in the blood in extremities. Let view its function in each of these.
Fish uses its gills to extract oxygen from the water and to drain carbon-dioxide and other metabolic wastes from the body. Gills pulls in water and when this water moves in the same direction of the blood the efficiency in extracting oxygen out of diffuses gradually. Hence, the gills make…
