Trachea is the main respiratory organ of grasshopper. It is fine, elastic and branched. Trachea wall consists of three layers. outer epidermis, middle epithelial and inner intima. Inside the trachea the intima forms a spiral or ring-like ring. These rings are called tinidia. Trachea never goes silent because of tineaea. The main trachea are arranged longitudinally and transversely to form 3 pairs of tracheal cords. These are the dorsal longitudinal tracheal cord, the lateral longitudinal tracheal cord, and the lateral longitudinal tracheal cord. Air flows through the trachea to the entire body.
