Chart the path of blood through the heart, including the valves passed. What will be an ideal response?
Blood enter the right atrium via the superior and inferior vena cavae. It then passes the right
atrioventricular valve and into the right ventricle. It is pumped from the right ventricle through the
pulmonary valve to the lungs. Blood returns from the lungs to the left atrium, and passes through the
left atrioventricular valve to the left ventricle. It is pumped out to the body through the aortic valve.
