Play from 5 min 30 seconds for a nice explanation of countercurrent flow
Recall:
In countercurrent flow - the blood flows in the opposite direction to the water. Describe: It maintains the concentration gradient along the whole surface gas exchange surface (lamella) Explain: This is an advantage because it allows for greater oxygen saturation of the blood (upwards of 80%) |
Can you identify which of the image represent counter current and parallel flow?
