The network of air tubes in insects for gas exchange is called __________
The network of air tubes in insects for gas exchange is called __________
The correct option is: A
Explanation of the correct option:
Insects have small openings on the sides of its body called spiracles. The spiracles are external openings located laterally along the thorax and abdomen of most insects.
Spiracles are openings of a network of tubes called tracheae which allows air to enter and exit the insect body. Air enters through the spiracles into the tracheal tubes and diffuses into the body tissues. Similarly, carbon dioxide from the cells enters the tracheal tube and moves out through the spiracles.
Explanation of the incorrect option:
Option B: Insects have small openings on the sides of its body called spiracles. The spiracles are external openings located laterally along the thorax and abdomen of most insects.
Option C: Insects have small openings on the sides of its body called spiracles. The spiracles are external openings located laterally along the thorax and abdomen of most insects.
Option D: Insects have small openings on the sides of its body called spiracles. The spiracles are external openings located laterally along the thorax and abdomen of most insects.
