allows blood to flow directly from the right atrium into the left atrium to bypass pulmonary circulation - foramen ovale carries blood from the umbilical vein to inferior vena cava; allows some blood to bypass the liver - ductus venosus atrial contraction; systole; p wave - atrial depolarization max volume of air that can be exhaled following maximal inhalation - vital capacity allows blood in pulmonary artery to flow directly into the descending aorta to bypass the pulmonary circulation - ductus arteriosus ventricular relaxtion; diastole; t wave - ventricular repolarization most important stimulus for the release of aldosterone - renin volume of air in lungs following maximal inhalation - total lung capacity provides oxygenated blood to brain - circle of willis aorta; left pulmonary veins; left atrium; left ventricle; bicuspid - structures that carry oxygenated blood (left heart) pulmonary arteries; vena cava; right atrium; right ventricle; tricuspid - structures that carry unoxygenated blood (right heart)transport unoxygenated blood from the fetus to the placenta - umbilical arteries transports oxygenated blood from the placenta to the fetus - umbilical vein volume of air that remains in lung after forceful exhalation - residual volume ventricular contraction; systole; qrs complex - ventricular depolarization located between left ventricle and left aorta - aortic semilunar valve located between right ventricle and pulmonary artery - pulmonic semilunar
