b. pumps oxygenated blood to the body.
c. contains the pulmonic and tricuspid valves.
d. pumps poorly oxygenated blood to the lungs.
Question 2Which of the following statements concerning the flow of blood to and through the right side of the heart is correct?
a. Blood reaches the right atrium from the aorta, is pumped through the mitral valve into the right ventricle, and is then pumped through the pulmonary veins to the lungs.
b. Poorly oxygenated blood reaches the right ventricle from the venae cavae, is pumped through the pulmonic valve into the pulmonary artery, and then enters the right atrium and is pumped into the lungs.
c. Oxygenated blood reaches the right atrium from the pulmonary veins, is pumped through the tricuspid valve into the right ventricle, and is then pumped into the aorta and throughout the body.
d. Poorly oxygenated blood reaches the right atrium from the venae cavae, is pumped through the tricuspid valve into the right ventricle, and is then pumped through the pulmonic valve and on to the lungs through the pulmonary arteries.

a. Septa
b. The coronary arteries
c. The atrioventricular valves
d. The pulmonary vein and the pulmonary artery
