Fichas del conjunto (7)
- 1What three problems with gaseous exchange do insects face?Insects are very active so need lots of oxygen
They have a tough exoskeleton so no gaseous exchange can occur
There are no oxygen carrying blood pigments - 2What are spiracles?Small openings along the thorax and abdomen
- 3How does air enter and leave insects?Through the spiracles
- 4How does air travel around the insect?Trachea lead away from the spiracles and these trachea divide into tracheoles.
- 5Why does air have to be transported around the insects rather than in blood?Insects don't have oxygen carrying pigments in the blood like humans do
- 6How do collapsible air sacs increase the uptake of oxygen?They act as air reservoirs, increasing the volume of air moving through the xchange system. They usually inflate and deflate bt movements of the abdomen
- 7Where does gaseous exchange take place in insects?Tracheoles
