The ductus venosus is a shunt that allows ____________________ . a. fetal blood to flow from the right atrium to the left atrium b. fetal blood to flow from the right ventricle to the left ventricle c. most freshly oxygenated blood to flow into the fetal heart d. most oxygen-depleted fetal blood to flow directly into the fetal pulmonary trunk
A. The left ventricle contracts and blood flows along the aorta to the body B. The blood flows through the tricuspid valve into the right ventricle. C. Oxygenated blood flows along the pulmonary veins into the left atrium D. The blood passes through the mitral valve into the left ventricle E. The left atrium contracts F. Deoxygenated blood flows from the inferior and superior vena cava into the right atrium. G. The deoxygenated blood picks up oxygen H. The right atrium contracts I. The right ventricle contracts and blood flows along the pulmonary artery to the lungs
