How does oxygen reach the inside of an insects body?

Answer 1

an insect is made up of cells so if oxygen is touching the insect it pretty much is at the cells of the insect its totally wrong don't listen to this person their saying preatty much because they don't know take my advise

Answer 2

all insects have little holes on the side of the body called spiraculi, find a large grass hopper and look carefully and you'll see them. they are conected to a chain of tubes called trachea which reach every single cell in the insects body.

Answer 3

Insects are a little different to you and me, with them being much smaller they can almost rely on direct diffusion (the movement of particles from high concentration to low concentration). This works by having small circular 'hatches' called spiracles on the sides of there bodies, and low amounts of oxygen in the needed areas. This means that the air rushes in and down the trachea's tubes, to the for example muscle, quick movement allows the concentration gradient to stay high and therefore diffusion rate.

But this system limits there size, as being too big they oxygen couldn't diffuse quick enough and the cells would die, also when the spiracle's are open transpiration takes place (water 'evaporates' off them) so when they need oxygen they lose water and vica versa.

Answer 4

Oxygen enters an insect's body through small openings called spiracles located along the insect's exoskeleton. From there, oxygen diffuses through a system of tubes called tracheae, which deliver oxygen directly to the insect's cells for respiration.

Answer 5

Normally insects respire through tracheal tubes.
