How do you build a working model heart out of easy-to-find materials?
Cartman29
You'll need 4 small plastic bottles for chambers
and two larger ones for the lungs,
clear tubing for blood vessels, a pump or two, since blood goes from the left ventricle to the aorta and from the right ventricle to the lungs at the same time, and modelling clay to leak proof the model. Remember to include the aorta, pulmonary veins, pulmonary areteries and vena cavas. Get the tubing from a hardware store and pump from a pet store (for a fish tank). You'll also need red food coloring and water for blood. You also need a box to put it in. Decorating the box is up to you.

What cardiac structure generates the action potentials that spread throughout the heart generating the cardiac contraction and the heartbeats?
In a normally functioning heart, the SA (sinoatrial) node is the pacemaker of the heart, but if it is nonfunctional then the AV (atrioventricular) node would take over. If it isn't working either then the Bundle of His can trigger contractions, and if it isn't working the Perkinje fibers can trigger contractions. Each progressive one has a slower intrinsic heart rate.
