What is the heart pump model?
This heart model is a great demonstration of one chamber of the heart and valve. The heart has two features that keep blood flowing in the right direction. Chambers fill with blood, then squeeze to pump the blood out. Each side of the heart has an entry chamber ( atrium ) and an exit chamber ( ventricle ).
How do I make a pumping heart model?
