What body parts do different animals use for breathing?

Generally the body parts used for breathing (exchanging gases with the atmosphere for respiration) are:

• lungs in most larger animals (mammals, reptile, birds)
• gills in aquatic animals (fish, amphibians, cephalopods)
• diffuse tracheal systems (insects)
• some animals use secondary methods of breathing as their gills or lungs are not sufficient for their needs (animals such as frogs and eels) they use their skin to supplement the gas exchange
