i like this topic!!!!

because of the LUNGS MODEL that we made last time!

it is so cute! because of the cigarette..
we use it to show how it effect when we smoke
.(because when we inhale, our diaphragm contracts, making the air outside our body which has a greater pressure than the air inside outside the body, rushed inside.. this process is called inhalation or inspiration. but when we exhale, our diaphragm relaxes and thus, going back to its normal position... the pressure outside our body will then have the greater pressure because the pressure inside the body released outside)..this is the explanation of our group
well, i realized that the cigarette is dangerous in our body
Well, thanks maam for the knowledge that you shared for us
