Hi, Kevin!

For the lungs, there's the classic "lung in a bottle" made of plastic
bottle (or cup), straws, tape, and balloons that makes an excellent and
very accurate demonstration of the role of the diaphragm and air pressure
in lung function.

Very long, thin plastic tubing is excellent to use for the aliminetary
canal and intestines. When a mixture of rice/oatmeal is put inside it,
students can line up and "squish" the tubing, passing the but contents
along, modeling peristalsis. at the end of the tube can be an old pair of
pantyhose over newspaper representing the colon; water will come out of the
pantyhose and will be absorbed by the paper, similarly as to how water is
absorbed by the body from the colon.

Tory Brady on staff here has a great working model of the heart made from
film cans, pieces of inner tubes, and bicycle spokes.

Write to me directly, Kevin, if you'd like more info on any of these, or
would like Tory's email address if you don't already have it.

Good luck!

---Karen
