Gas Exchange System in Bony Fish Quiz

What is the flap of tissue called that is found on either side slightly behind the head of bony fish?

• Gill lamellae

• Buccal cavity

• Operculum

• Gill arch

What is the function of the gills in bony fish?

• To exchange gases between water and blood

• To regulate body temperature

• To provide structural support

• To filter out food particles from the water

What is the advantage of the counter current exchange system in bony fish?

• It reduces the surface area for gas exchange

• It increases the diffusion distance through the gill lamellae

• It maintains a steep concentration gradient for oxygen

• It allows for a higher concentration of carbon dioxide in the blood

What is the mechanism that allows water flow to occur through the gas exchange system in bony fish even when the fish is not swimming?

• Swimming forward

• Squeezing the opercular cavity

• Opening and closing the mouth

• Flapping the operculum

What is the main function of the buccal cavity in bony fish during the gas exchange process?

• To store excess water

• To increase the pressure of the water

• To decrease the volume of the water

• To regulate the flow of water over the gills

What is the role of the gill lamellae in the gas exchange system of bony fish?

What is the purpose of the gill arches in bony fish?

• To regulate the flow of water over the gills

• To produce mucus for protection

• To provide structural support for the gills

• To increase the surface area for gas exchange

What is the function of the operculum in bony fish during the gas exchange process?

• To store excess water

• To regulate the flow of water over the gills

• To decrease the volume of the water

• To increase the pressure of the water
