Q

Which of the following statements is correct with regard to blood as it travels through the cardiovascular system:
A. Blood in the right ventricle passes through the pulmonary trunk to the pulmonary artery to the lungs, returns oxygenated via the pulmonary veins
toward the left atrium, then passes through the tricuspid valve to the left ventricle, out through the aorta and then to the body, where it gets deoxygenated at the level of the body tissues and then returns via the superior or inferior vena
cava to the right atrium.
B. Blood in the right ventricle passes through the pulmonary trunk to the pulmonary veins to the lungs, returns oxygenated via the pulmonary artery
toward the left atrium, then passes through the bicuspid valve to the left ventricle, out through the aorta and then to the body, where it gets deoxygenated at the level of the body tissues and then returns via the superior or inferior vena
cava to the right atrium.
C. Blood in the left ventricle passes through the pulmonary trunk to the pulmonary artery to the lungs, returns oxygenated via the pulmonary veins
toward the right atrium, then passes through the tricuspid valve to the right ventricle, out through the aorta and then to the body, where it gets deoxygenated at the level of the body tissues and then returns via the superior or inferior vena
cava to the left atrium.
D. Blood in the right ventricle passes through the pulmonary trunk to the pulmonary artery to the lungs, returns oxygenated via the pulmonary veins
