Question 1 10 out of 10 points 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. Caval veins - return deoxygenated blood from the body to the right atrium. 2. pulmonary veins - receives oxygenated blood from the lungs 3. pulmonary artery - pumps blood to the lungs 4. aorta - pumps blood to the body The heart is considered a double pump because the right side of the heart receives blood from te body and pumps it into the lungs and the left side receives blood from the lungs and pumps it to the body Both pumps work simultaneously. Both atria contract together followed by contractions of both ventricles. 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).
