HEYA MATEY :)

Fish use specialized surfaces called gills to carry out gas exchange.

Gills are highly folded, giving them a large surface area and maximizing the efficiency of gas exchange.  The gill filaments have many protrusions called gill lamellae.

Efficient gas exchange in fish is due to:

-large surface area of gills due to gill lamellae

-countercurrent principle

-rich blood supply of lamellae

-water being able to flow in one direction only
