Question

What type of respiratory system do insects have?

Answer 1

Respiratory system:

1. The respiratory system is a biological system in animals and plants that consists of distinct organs and structures required for gas exchange.
2. The anatomy and physiology that allow this to happen vary widely depending on the organism's size, habitat, and evolutionary history.

Respiratory system of insects:

1. In most insect species, the trachea is the primary organ responsible for respiratory function.
2. Spiracles are exterior openings found on insects.
3. The air enters the body through these spiracles and travels to the trachea, which is part of the internal respiratory system.
4. The muscularity around the spiracle's entrance is such that it only opens and closes when necessary to avoid moisture loss.
5. The muscle must relax in order to open the spiracle's aperture.
6. Although muscle movement is governed by the central nervous system, it can also occur as a result of a response to external stimuli at times.
7. The trachea is a complex network of tubules capable of maintaining pressure throughout the body.
8. Tracheal tubes are split into smaller tubes that connect to every area of the body.
9. A unique cell known as a tracheole may be found at the end of each branch of the trachea.
10. The tracheole serves as a surface for the exchange of gases between the environment and the body's cells.
