In cockroach, the site for gaseous exchange is:
Correct answer: D. Tracheole
- A. Cuticle
- B. Trachea
- C. Spiracle
- D. Tracheole
Explanation
In cockroaches, the respiratory system consists of a network of tubes called tracheae, which branch into finer tubes called tracheoles. These tracheoles penetrate tissues and facilitate the exchange of gases (oxygen and carbon dioxide) directly with cells. The cuticle is mainly protective, spiracles are entry points for air, and the trachea distribute the air, but the tracheoles are where the actual exchange happens.

About Human Respiratory System
The human respiratory system conducts air to the alveoli, where oxygen and carbon dioxide exchange occurs across thin respiratory surfaces. Questions cover the nasal passage, trachea, bronchi, lungs, diaphragm and intercostal muscles, ventilation mechanics and gas transport, while distinguishing breathing and gaseous exchange from cellular respiration.
