Answers


Isacko
example is cockroach

air in the atmosphere contains oxygen

air is drawn into the body of the insect through the spiracles due to movement of abdominal muscles

these movements cause the opening of spiracles

air moves through the trachea to tracheoles

oxygen moves from the tracheoles into body cells by diffusion due to concentration gradient

carbon iv oxide in the tissues diffuses into tracheoles due to concentration gradient

From tracheoles carbon IV oxide moves into trachea and out through the spiracles into the air.
