Explain the structures of respiratory organs for the exchange of gases in various groups/kingdoms of animals.
(N/A) Mechanisms of breathing vary among different groups of animals,depending mainly on their habitats and levels of organization. Simple organisms exchange gases by simple diffusion over their entire body surface,while complex organisms have evolved specialized respiratory organs.
| $1$. Animal Group | $2$. Respiratory Organ |
| Lower Invertebrates (Porifera,Coelenterata,Platyhelminthes) | Entire body surface (Diffusion) |
| Annelida | Moist cuticle (Cutaneous respiration) |
| Arthropoda (Insects) | Tracheal system |
| Arthropoda (Aquatic - Crustaceans) | Gills (Branchial respiration) |
| Arthropoda (Arachnids) | Book lungs/Book gills |
| Mollusca | Gills (Ctenidia) |
| Echinodermata | Tube feet/Dermal branchiae |
| Amphibians | Moist skin,lungs,and buccal cavity |
| Reptiles,Birds,Mammals | Lungs (Pulmonary respiration) |
| Fishes | Gills |
