Do Insects Have Lungs?

In order to live, all animals need to take in oxygen and send it into their blood stream. Land creatures use their lungs to take this oxygen from the air, and fish use their gills. But insects have neither
lungs nor gills! So how do they breathe?

The body of an insect is filled with tracheae, a system of tubes that run through its body like blood veins. These tubes are connected to openings in the insect’s skin.

The movement of the insect’s muscles pumps air through the openings and into the tracheae, and the air travels through the tracheae to all parts of the insect’s body.
