Heart Anatomy All parts of the body, superior and inferior vena cava, right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary arteries, lungs, pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic valve, and aorta

Facts about the Heart 72 beats per minute Blood vessels: arteries, veins, capillaries Size of heart: one fist Lies in thoracic cavity, between the lungs Heart tissues: endocardium, myocardium, epicardium, pericardium Cardiac conduction system: node (SA), (AV) node, bundle of his, bundle branches, purkinje fibers

Health Concerns Heart attack: coronary artery becomes blocked Heart disease: condition the involves the heart, vessels, muscles, valves, or internal electric pathways Coronary artery disease: plaque partially obstructs coronary arteries and reduces blood flow Congestive heart failure: over time the hearts pumping action cannot meet the body's demand

Testing Cardiac CT: detailed 3-D images of heart Stress test: measures ability of a person's heart to respond to the body's demand for more blood during stress Holter monitor: worn for 1 or 2 days and provides continual EKG like recording of the heart Chest x ray: used to provide the doctor with a view of the heart and lungs Echocardiogram: a real time moving picture of a heart made by using sound waves Catheterization: a thin tube placed in a blood vessel in a leg and treated into the heart
