Study Notes
- The hearts muscle is referred to as the Myocardium
- Blood does not enter the right atrium through the mitral valve.
- Blood enters the right atrium via the superior vena cava, inferior vena cava, and coronary sinus
- Fossa ovalis refers to the depression between the right and left atrium
- The tricuspid valve separates the right atrium from the right ventricle
- Freshly oxygenated blood returns to the heart via the pulmonary veins
- The S2 heart sound results from the closure of the aortic and pulmonic valves.
- The sinoatrial node is located high in the right atrium
- Excitability refers to the ability of cardiac cells to respond to electrical impulses
- Baroreceptors sense the pressure in the heart or arteries
- Magnesium is not one of the three major ions responsible for electrical conduction in the heart.
- Calcium, Sodium and Potassium are responsible for electrical conduction in the heart
- A resting cell with a net negative charge compared to the outside of the cell is considered polarized
- The QRS complex of an ECG represents the depolarization of the ventricles
- Afterload refers to the pressure in the aorta against which the left ventricle must pump blood
- Ejection fraction refers to the percentage of blood pumped out during systole
- The ascending aorta is not a major artery that arises from the aortic arch
- The basilar artery supplies blood to the pons and cerebellum
- The external and internal jugular veins join at the base of the neck
- The great saphenous vein is the longest vein in the body
- Cardiac output is expressed as liters per minute
- Mesenteric infarct is suspected, with intestinal pain and a history of atherosclerosis
