5 True/False Questions
Myocardial infarction → The space between the visceral and parietal pericardium, is filled with a thin layer of serous pericardial fluid.
Gap junctions → Allow cytoplasm to flow freely between cells, resulting in areas of low electrical resistance between the cells.
Parietal Pericardium → the part of the serous pericardium lining the fibrous pericardium.
Fibrous rings → is formed by the heart skeleton, which surround the atrioventricular and semilunar valves and provides solid support for them, reinforcing the valve openings.
Ventricular systole → The atria open into the ventricles thru this, it's a passage way that the atria open into to get to the ventricle.
