PATHOLOGY

Detailed explanation-1: -the tracheal respiratory system of insects is a light-weight, tubular system for exchanging gases between atmosphere and tissue. Its basic structure consists of tracheal tubes, which are formed from invaginations of the entire integument of the cuticle.

Detailed explanation-2: -Instead of breathing in air, grasshoppers use tiny holes located on their abdomen called Spiracles; the Spiracles are located along both sides of the abdomen and are used to bring air into the grasshoppers body.

Detailed explanation-3: -Insects have spiracles on their exoskeletons to allow air to enter the trachea. In insects, the tracheal tubes primarily deliver oxygen directly into the insects’ tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss.
