  1. Myocardial infarctionThe space between the visceral and parietal pericardium, is filled with a thin layer of serous pericardial fluid.


  2. Gap junctionsAllow cytoplasm to flow freely between cells, resulting in areas of low electrical resistance between the cells.


  3. Parietal Pericardiumthe part of the serous pericardium lining the fibrous pericardium.


  4. Fibrous ringsis formed by the heart skeleton, which surround the atrioventricular and semilunar valves and provides solid support for them, reinforcing the valve openings.


  5. Ventricular systoleThe atria open into the ventricles thru this, it's a passage way that the atria open into to get to the ventricle.
