1. T F The heart is located inside the mediastinum.
2. T F The parietal peritoneum attaches to the diaphragm.
3. T F Cardiac tamponade can be caused by pericarditis.
4. T F The myocardium has both gap junctions and intercalated discs to increase electrical resistance.
5. T F The apex of the heart always contains the left and the right atrium.
6. T F The pectinate muscles help to reduce the shock on the chordae tendineae.
7. T F The common cause of rheumatic heart disease is repeated Staphylococcus bacterial infections.
8. T F The left side of the heart is larger with thicker myocardium and therefore pumps a greater volume of blood.
