The respiratory system of the grasshopper is called the tracheal system. The trachea or trachea and its branches join together to form a special type of respiratory system called tracheal system. Oxygen from the environment enters the body cells through the branches of the trachea and CO2 is released from the body cells in the same way. Different parts of the tracheal system are trachea, trachea and tracheole.
1. Spiracles: There are 10 pairs of spiracles in the pleura on both sides of the body. Of these, 2 pairs are located in the thoracic region and 8 pairs are located in the abdominal region. Each spiracle has a distinct ovoid pore. Spiracles are covered by peritrim. Pores are lined with hairy sieves. The bristled filter prevents the ingress of dust, germs and water.
2. Trachea or trachea: 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.
3. Tracheole: The trachea divides to form fine branches called tracheole. It is unicellular, without intima and tinidia and unbranched. Its diameter is 1 µm. It is filled with fluid. Oxygen and CO2 circulate in this liquid. Some branches of the trachea expand to form air sacs. Air is stored in the air sac. Dr. Siddiq Publications
