Question

Trace a drop of blood as it enters the heart,
goes through pulmonary circulation, returns to
the heart, and goes to body cells. Name each
chamber and valve in the heart, each blood vessel or type of vessel, and any organs blood
passes through. Make sure all parts are in
correct order.

Answer 1

Hopefully this is right:
Comes in through superior and inferior vena cava, then enters right atrium, then tricuspid valve and into the right ventricle. Then the deoxygenated blood gets pumped through the pulmonary artery to the lungs. Oxygenated blood comes back through pulmonary vein and into left atrium. Then goes through mitral valve and into left ventricle which then pumps the blood through aorta.
