Question

Explain the process of exchange of gases in insect

Answer 1

Answer:

Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae.

Explanation:

Tracheae open to the outside through small holes called spiracles. In the grasshopper, the first and third segments of the thorax have a spiracle on each side. Another 8 pairs of spiracles are arranged in a line on either side of the abdomen.

Answer 2

• Insects such as cockroach and grasshopper have a tracheal system running all along their body. The air tubes

called trachea open through small openings called spiracles for exchange of gases. Insects lead a very active life

and need more amount of oxygen. The tracheal system provides them with sufficient oxygen.
