Name 1) the veins that enter the right atrium; name 2) those that enter the left atrium. For each, where does the blood come from?Name 3) the artery that leaves the right ventricle; name 4) the artery that leaves the left ventricle. For each, where is the blood going?5) Explain why the heart is considered a double pump. Selected Answer: 1) superior vena cava/upper body & inferior vena cava/lower body 2) left pulmonary veins/left lung, right pulmonary veins/ right lung 3) pulmonary artery/lungs 4) aorta/body 5) The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs while the left side of the heart receives oxygenated blood from the lungs and pumps it to the body. Both sides of the heart work at the same time. Correct Answer: 1) Superior vena cava - upper body; Inferior vena cava - lower body 2) Left pulmonary veins (2) - left lung; Right pulmonary veins (2) - right lung 3) Pulmonary artery - lungs 4) aorta - body 5) The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs; the left side of the heart receives oxygenated blood from the lungs and pumps it to the body. Both sides of the heart work simultaneously (atria contract together, then ventricles contract).
