Spiracles
The respiratory system of insects is called the tracheal system. It consists of a network of branching tubes called tracheae that deliver oxygen directly to the cells and remove waste gases. These tubes have openings called spiracles on the surface of the insect's body.
tracheal tubes
The adjectival form of "trachea" is "tracheal." This term is used to describe anything related to the trachea, such as tracheal tissues, tracheal inflammation, or tracheal tubes.
Cockroaches have a system of tracheal tubes that bring oxygen directly to their cells for respiration. Air enters the body through small openings called spiracles and travels through the tracheal tubes to reach all tissues. The waste product, carbon dioxide, is then expelled through the spiracles.
Tracheal tubes
Grasshoppers and most insects 'breath' though Spiracles located along the sides of their bodies. These openings feed a net of branching tubes that get oxygen directly into the insects body and tissues.
Large tracheal tubes
They respire through spiracles.
