How does an insect ventilate its body?

The insect pumps its abdomen, drawing air in and out of the trachea via the spiracles.

1 of 8

where does the air move into within the insect?

Air moves within the tracheoles and arrives directly into the muscle tissue

2 of 8

How does the air enter through the insect?

Through spiracles

3 of 8

why should occasionally the spiracles close?

to prevent water loss

4 of 8

what do the hairs around the spiracles help do?

Helps trap humid air to prevent water loss

5 of 8

What happens if the end of the tracheoles is filled with water? how can this end of the tracheol be free?

when the muscle respires they produce lactate, which lowers the water potential, and so allowing the high concentration of water to enter within the cells via osmosis

6 of 8

What happens when the muscle respires within insects?

there will be a diffusion gradient when the muscle respires thus producing oxygen within the muscles and carbon dioxide into the surroundings

7 of 8

Define mass transport?

Contractions of muscles which squeeze tarcheoles allowing air to be moved through
