Question

multiple choice question
which of the following describes the path of a blood cell from the superior vena cava as it makes its way through the heart?
o right atrium -> right ventricle -> pulmonary artery -> lung -> pulmonary vein -> left atrium -> left ventricle -> aorta
o left atrium -> left ventricle -> aorta -> pulmonary artery -> lung -> pulmonary vein -> right atrium -> right ventricle
o left atrium -> left ventricle -> aorta -> pulmonary vein -> lung -> pulmonary artery -> right atrium -> right ventricle
o right atrium -> right ventricle -> pulmonary vein -> lung -> pulmonary artery -> aorta -> left atrium -> left ventricle

Explanation:

Blood from the superior vena cava enters the right atrium. It then goes to the right ventricle, is pumped to the lungs via the pulmonary artery, returns from the lungs through the pulmonary vein to the left atrium, then to the left ventricle, and is pumped out to the body through the aorta.

Answer:

right atrium -> right ventricle -> pulmonary artery -> lung -> pulmonary vein -> left atrium -> left ventricle -> aorta
