What is the path of blood through the heart starting with the right atrium and ending with the Aorta (include all veins, arteries, valves, and chambers).
Blood enters the right atrium and from the superior and inferior vena cava. Blood then passes through the tricuspid valve and into the right ventricle. When the right ventricle contracts, blood is pumped through the pulmonary valve( which closes to prevent the blood from flowing back into the right ventricle) into the pulmonary arteries which carry the deoxygenated blood to the lungs. After passing through the pulmonary arteries, arterioles, and capillaries, the blood is oxygenated and passes into the pulmonary venules and then pulmonary veins. The pulmonary veins carry the oxygenated blood into the left atrium. The blood then flows through the bicuspid valve and into the left ventricle. When the ventricle contracts, the blood flows through the open semi-lunar valve (which closes after the contraction in order to prevent backflow) and into the aorta.
