tracheas
Airways to lungs
Tracheas is the plural of trachea, the tube that carries air from the throat to the lungs—the windpipe.
In anatomy, it refers to this structure in humans and other vertebrates.
In insects and some other invertebrates, tracheae are the network of tubes that deliver oxygen directly to tissues.
The doctor examined several patients' tracheas for signs of inflammation.
