CO2 is removed from insect tissues by diffusion down its concentration gradient, from the respiring tissue through tracheoles and tracheae out of open spiracles.
- CO2 produced in respiration - high CO2 concentration in respiring tissue - <b>when spiracles are open</b> - CO2 diffuses out of respiring tissue down diffusion gradient - CO2 diffuses through tracheoles and trachae out of spiracles down diffusion gradient
