Solution
The correct option is B Trachea
Insects like grasshoppers, cockroaches and houseflies do not have lungs like human as a part of respiratory system. They have simple gas exchange system for breathing. They have tracheal system to deliver oxygen directly to each cell in the body. They breathe by means of long tubes called as tracheae. Oxygen enters through spiracle, the opening of trachea. After reaching tracheae, oxygen permeates into the body tissue and reaches every cell of the body. Carbon dioxide goes into the tracheae and moves out through the spiracles.Thus, the correct answer is option B.
