3. Key Vocabulary: Systole, Diastole, Bradycardia, Tachycardia, Angina Pectoris, Electrocardiogram, P-Wave, QRS-Complex/Wave, T-Wave, Vasoconstriction, Vasodilation Artery, Vein, Capillary, Arteriole, Venule, Lumen **All vocabulary words above are found in the 7 page packet, that starts with “The Pulmonary & Systemic Circuit”

4. The Pulmonary and Systemic Circuit The pulmonary circuit – HEART TO LUNGS AND BACK The systemic circuit – HEART AND BODY AND BACK

5. Electrical Conduction System of the Heart Be able to: 1.Label all electrical conducting structures: SA Node (pacemaker), AV Node, Bundle of His, Bundle Branches, Purkinje fibers 2.Show the path or identify the path of impulse conduction 3.Correlate what is occurring in these structures to an ECG.

6. ECG- Electrocardiogram What happens at the P wave? What happens at the QRS complex? What occurs just after the R wave? What occurs at the T Wave?

7. Heart Sounds Lupp Dupp First heart sound (shorter)– AV valves close, semilunar valves open Second heart sound – Semilunar valves close Know all the names of the AV valves – Left AV valve= Mitral valve, Bicuspid Right AV valve = Tricuspid valve
