1.) The water inside the jar represents the blood that is pumped by the heart.
2.) The heart pump model moves water from the jar through the straws and into the pan. The heart pumps blood out into the body through the arteries in a similar way.
3.) The heart is filled with blood which is squeezed out to circulate through the whole body.
4.) No. The blood will not be pumped out of the heart into the body because there is an obstruction.
