QuestionChoice
The image shows a posterior view of the heart. The arrow indicates one of the chambers located at the superior end of the heart. This chamber is on the left side, so it is the left atrium, which receives oxygenated blood from the lungs through the pulmonary veins. Blood from the left atrium subsequently travels to the left ventricle to be pumped out through the aorta.

a
Receives oxygenated blood from the lungs via the pulmonary veins
QuestionChoice
The image shows a posterior view of the heart, and the arrow is pointing to the left atrium. This answer is incorrect – none of the chambers of the heart receive deoxygenated blood from the lungs through the pulmonary arteries. The pulmonary arteries transport deoxygenated blood from the right ventricle to the lungs.

c
Receives deoxygenated blood from the lungs via the pulmonary arteries
QuestionChoice
The image shows a posterior view of the heart, and the arrow is pointing to the left atrium. This answer describes the function of the left ventricle, which transports oxygenated blood via the aorta to the rest of the body. However, the indicated chamber is located superiorly, so it is the left atrium.
