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.
