| 3. | A nurse is educating a group of students about the structure and function of the cardiovascular system and its components. The nurse is educating the nursing students about the layers within arteries and veins of the heart. What does the nurse tell the students is the function of the tunica media layer? | |

| B) | This layer contains the thickest elastic fibers, as well as connective tissue composed of polysaccharides. | |
| C) | This layer protects the outside of the vessel. | |

| 5. | A nurse is educating a group of nursing students about the heart’s chambers and the muscular septum wall. What information by a nursing student demonstrates a correct understanding about the four chambers into which the heart is divided?
1. The interior of the heart is divided into two chambers. 2. The thin-walled, low-pressure chambers are the receiving centers for blood. 3. Ventricles are high-pressure chambers because they pump blood out of the heart. 4. The left ventricle is the thickest chamber and it pumps blood to the rest of the body. |
