Respiration physiology the machinery of fish breathing

This part will give a short overview of the respiratory system in fish. In the lab exercise in this activity you will be able to test how flow affects the exchange of gases, and get a better understanding of the problems fish encounter in order to get oxygen from water.

The assignment find out the answers!

  • How are the fish gills constructed, and how does this intricate machinery actually work?
  • What is important for the uptake of oxygen
  • How is blood and water pumped over the gills?
