Study Notes
Respiratory Mechanisms in Animals
- Animals use various mechanisms to exchange gases, adapting to their environment and complexity
- Organisms like sponges, coelenterates, flatworms, etc., exchange O2 and CO2 through simple diffusion throughout their bodies.
- Earthworms use their moist cuticle, and insects possess a network of tubes (tracheal tubes) to transport air.
- Aquatic arthropods and molluscs utilize specialized vascularized structures called gills.
- Terrestrial animals (reptiles, birds, and mammals) employ vascularized bags (lungs) for gas exchange.
- Amphibians can breathe through their moist skin.
- Mechanisms vary in complexity based on habitat and levels of organization
- Mammals have a complex respiratory system.
