Adaptations of fish gill to gaseous exchange

Adaptations of fish gill to gaseous exchange

1. Gills are red- rich blood supply
2. many tiny gill filaments increase surface area for gaseous exchange
3. Gill lamellae is flat to help increase their surface area for oxygen exchange
4. Water enters the mouth and comes out through operculum
5. Water passes over the gills
6. Epithelium covering gills is only one cell thick reducing diffusion gradient.
7. Gill filaments are protected from damage by operculum
