QUESTIONS AND ANSWERS RATED A+
✔✔baroreceptors - ✔✔detect changes in blood pressure; located in the aorta & carotid
arteries
✔✔ epicardium - ✔✔the outer layer of the heart (visceral pericardium)
✔✔myocardium - ✔✔middle muscle layer of the heart

the surface of the valves
✔✔pericardium - ✔✔membranous, fluid-filled sac surrounding the heart
✔✔Myocardial infarction - ✔✔heart attack
✔✔Arrhythmia - ✔✔Abnormal heart rhythm or heart rate
✔✔hypertension - ✔✔high blood pressure, sustained 140/90
✔✔Systole - ✔✔contraction phase of the heart; myocardium contracts to move blood
✔✔atrioventricular valve - ✔✔valves that separates the atria from the ventricles
✔✔atrium - ✔✔upper filling/ receiving chamber of the heart
✔✔ventricle - ✔✔lower/ pumping chamber of the heart, contracts
✔✔right side of the heart - ✔✔responsible for pulmonary circulation, moving
deoxygenated blood to lungs
✔✔left side of the heart - ✔✔responsible for systemic circulation, moving oxygenated
blood to body
✔✔name of AV valve on left side - ✔✔bicuspid valve or Mitral valve
✔✔pulmonary semilunar valve - ✔✔valve between right ventricle and pulmonary artery
✔✔aortic semilunar valve - ✔✔valve between left ventricle and aorta
✔✔diastole - ✔✔relaxation portion of cardiac cycle; myocardium is relaxed and not
actively pumping
