Explain about respiration in cockroach?
Answers
Answer:
Respiration in cockroaches
A cockroach is an insect whose body is covered with air holes called as spiracles.
*Air enters through these air holes on the body and finally reaches the trachea.
*Trachea are a network of fine air tubes extending through out the body.
*Trachea help in circulating the oxygen throughout the body.
*The oxygen in the air diffuses into the tissues and is ultimately absorbed by the cells.
*The carbon dioxide released by the cells is carried by the trachea and given out through the spiracles.

Answer:
In cockroach, respiration takes place through a small openings on the sides of its body called spiracles. When the air enters the respiratory system of a cockroach through these external openings, spiracles act as muscular valves, leading to the internal respiratory system. The respiratory organ of cockroach is known as tracheae.
The trachea is a dense networked array of air tubes in the internal system. These tracheae balance the pressure within the system. As the oxygenated air from the atmosphere enters into the cockroach’s body through the spiracles into the tracheal tubes, it penetrates into the different cells and tissues of the body, where the oxygen gas is utilized to release energy. Similarly, the air rich in carbon dioxide, which is the product of the respiratory process, goes into the tracheae and moves out through the spiracles.
