TRACHEA

'Trachea' is a common rottenfor an airway through which respiratory air transport takes place in organisms.

★ Vertebrate trachea, in terrestrial vertebrates, such as birds and humans, the trachea allows oxygen and carbon dioxide to move from the throat to the lungs

★ Invertebrate trachea, in terrestrial invertebrates, such as onychophorans and insects, tracheae conduct air from outside the organism directly to all internal tissues
