Question

What is the role of the swim bladder in fish and air sacs in birds?

Answer

Swim bladder in fish:

  • Buoyancy control: It helps fish regulate their depth in the water column by adjusting the amount of gas (usually oxygen) in the swim bladder.
  • Maintains neutral buoyancy: By controlling the gas volume, fish can stay suspended at a specific depth without exerting much energy for swimming.

Air sacs in birds:

  • Oxygen exchange: Air sacs act as a reservoir, allowing continuous one-way airflow through the lungs, ensuring efficient oxygen exchange during both inhalation and exhalation.
  • Enhanced respiration: Air sacs enable a constant supply of fresh oxygenated air, improving the efficiency of oxygen transport and facilitating high metabolic demands during flight.
