AS Biology - Breathing in bony fish (OCR A Chapter 7.4)

The breathing mechanism in bony fish is similar to that of mammals - it relies on the changing of cavity volume to change the pressure, resulting in a flow of air or water into or out of the body. Here in bony fish, there are two cavities to consider: buccal cavity (mouth) and opercular cavity (between gills and opercular valves). In this video we will go through how the cavities' volumes and pressures change throughout fish breathing.
