| Pulmonary and aortic valves located between the right ventricle and pulmonary artery and between the LV and aorta | semilunar valves |
| two layer sac surrounding the heart consisting of external fibrous and internal serious layer | pericardium |
| outer linning covering the heart | epicardium |
| middle thick muscular layer of the heart | myocardium |
| inner lining of the heart | endocardium |
| tubelike structures that carry blood throughout the body | blood vessels |

| venules | SMALLEST VEINS |
| largest vein in the body | vena cava |
| microscopic blood vessels that connect arterioles with venules | capillaries |
