What is the function of an air bladder?

Vijay shinde said:   9 years ago
The swim bladder is located in the body cavity and is derived from an out-pocketing of the digestive tube.

It contains gas (usually oxygen) and functions as a hydrostatic, or ballast, organ, enabling the fish to maintain its depth without floating upward or sinking.

Air sacs are found in the lungs which is the alveoli and swim bladder is for buoyancy in water.
