Respiratory organs in animals, irrespective of their habitat, have structures that increase the surface area for contact with the oxygen-rich atmosphere. These surfaces are often delicate, protected within the body, and connected to air passages for efficient oxygen exchange.

The common feature among respiratory organs in animals living in various environments is the presence of structures that increase the surface area for contact with the oxygen-rich atmosphere. Whether in terrestrial or aquatic environments, respiratory organs share the characteristic of having fine and delicate surfaces, often protected within the body. These surfaces are intricately connected to air passages, facilitating the efficient exchange of gases, ensuring that oxygen is absorbed and carbon dioxide is released. The adaptation of respiratory structures with increased surface area optimizes the respiratory efficiency of animals, regardless of the environmental challenges they face.
