Answer:
Deoxygenated blood enters the right atrium from the superior and inferior vena cava > The blood flows through the tricuspid valve into the right ventricle >From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery > The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange > The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen > The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium > From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle > Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation
