3. Only I, II, III, and V
4. Only I, III, and IV
| I: | The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. |
| II: | The pulmonary veins carry oxygenated blood from the lungs to the left atrium. |
| III: | The systemic circulation provides nutrients, O2, and other essential substances to tissues and removes CO2 and other harmful substances. |
| IV: | The hepatic portal vein carries blood from the liver to the intestine before it is delivered to the systemic circulation. |
| V: | The coronary system is responsible for the circulation of blood to and from the cardiac musculature. |
