1. Lung
An organ found in air-breathing vertebrate animals which functions in air respiration . It transfers atmospheric oxygen from the air to the blood, and carbon dioxide and other waste gases from the blood to the air. Most animals have a pair; one species of lungfish has just one, and other primitive fish may have lunglike air bladders (the swim bladder, found in many bony fishes, evolved from the lung).

2. Lungfish
