NEETZoologyBreathing and Exchange of Gases
Respiration in insects is called direct because
Options
- AThe cell exchanges O₂/ CO₂ directly with the air in the tubes
- BThe tissues exchange O₂/ CO₂ directly with coelomic fluid
- CThe tissues exchange O₂/ CO₂ directly with the air outside through body surface
- DTracheal tubes exchange O₂/ CO₂ directly with the haemocoel, which then exchange with tissues
Correct answer
D. Tracheal tubes exchange O₂/ CO₂ directly with the haemocoel, which then exchange with tissues
Step-by-step solution
Direct exchange of gases occurs in insects as Tracheal tubes exchange O₂/ CO₂ directly with the haemocoel, which then exchange with tissues.
