Human Respiratory System Working Model 3d Lung Model For о This lung model demonstrates how the lungs work. air is taken in through the mouth and nose, passes down the windpipe and into the lungs. the diaphragm at the bottom of our chest moves down to create more space. as we breathe out the diaphragm raises again. the knotted balloon represents the diaphragm and the balloon inside the container. We use various muscles to increase chest volume more dramatically. in the same way as in relaxed breathing the expansion of the chest cavity draws air in so the lungs fill up. the relaxation of the chest cavity pushes air out. muscles can also force the chest cavity to contract even further, pushing even more air out.

Step 1: cut the bottom off your plastic bottle. when you choose your bottle, make sure it is big enough to hold the size of balloons you have, and that the bottle is somewhat sturdy. i used a 2 liter soda bottle, it was just sturdy enough and as i had bigger balloons, it was better to be wider than a smaller bottle. Your human respiratory system model is ready to show off! this is a fantastic project idea for the science fair or as part of a biology unit study to really show your understanding of the human respiratory system. respiratory system unit study printable. building a lung model is a fantastic way to learn how the human respiratory system works. A model of the lungs. pull the diaphragm (balloon) down (that is, away from the lungs) in order to inflate the lungs. (note: this makes the chest cavity larger and decreases the pressure.) push the diaphragm (balloon) in (towards the lungs) in order to deflate the lungs.

Using the balloon half with the knot, stretch the open end over the bottom of the bottle. again, this should be a tight fit. use tape to secure if necessary. gently pull down on the balloon from the knot. this should cause air to flow into the balloons within your lung model. release the balloon with the knot and watch as the air is expelled. Tie a knot at the end of the remaining balloon and cut the large part of the balloon in half horizontally. using the balloon half with the knot, stretch the open end over the bottom of the bottle. gently pull down on the balloon from the knot. this should cause air to flow into the balloons within your lung model.
