-
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. It facilitates the exchange of oxygen from the atmosphere into the body and the removal of carbon dioxide from the body to the atmosphere.
-
The main types of respiratory systems found in animals include:
- Cutaneous respiration: Gas exchange through the skin (e.g., earthworms, amphibians).
- Tracheal system: A network of tubes that carry oxygen directly to tissues (e.g., insects).
- Gills: Specialized organs for gas exchange in water (e.g., fish, crustaceans).
- Lungs: Internal organs for gas exchange in air (e.g., mammals, birds, reptiles, some amphibians).
