Blood Composition WBC (granular and agranular), RBC, Platelets, Plasma, Serum Heart Anatomy Be able to label the different parts of the heart Blood Flow Be able to trace the flow of blood through the heart Cardiac Conduction System Know the different components of the CCS and how the impulse flows through the heart SA Node, AV Node, AV Bundle, Purkinje Fibers ECG What happens during each wave of the electrocardiogram Know the different abnormalities that we discussed in class Heart Disorders Study the jigsaw fact sheet; specifically know what each disorder is It seems like a lot, but you’ve got this!! B A N C M D L E F K G J I H 1. _______ Aorta A. Wave that indicates ventricular repolarization 2. _______ Plasma B. Delivers oxygen to every cell in the body 3. _______ Red Blood Cells C. Delay in signal 4. _______ Platelets D. Receives deoxygenated blood from the body 5. _______ White Blood Cells E. Connects atria to ventricles 6. _______ Right Atria F. > 100 beats per minute 7. _______ Left Atria G. Receives oxygen rich blood from the lungs 8. _______ Right Ventricle H. Branches off the heart and then divides into smaller arteries 9. _______ Left Ventricle I. Stops you from bleeding to death by forming clots 10._______ Valve J. Natural pace maker of the heart 11._______AV Node K. Defend the body from infection 12.______SA Node L. Pumps blood to entire body 13._______P Wave M. Wave that indicates atrial contraction 14._______T Wave N. Pumps blood to the lungs 15._______Tachycardia O. Made of mostly water Trace the flow of electricity through the heart to conduct one cardiac cycle. Which part of the CCS is known as the hearts natural pacemaker? Stimulation from which nerve decreases the activity of the SA Node and the AV node? The AV bundle leads the depolarization into the ______ of the heart along the purkinje fibers. The individual cells in the heart do not act in unison. True or False Describe what occurs during the T Wave. Describe what occurs during the P Wave. Describe what occurs during the QRS Wave. List and briefly describe two ECG abnormalities. ____1. Accumulation of plaque buildup on walls of arteries A. Hypertension B. Coronary Artery Disease ____2. One or both cusps of mitral valve stretches and bulges into left atrium during ventricular contraction. C. Myocardial Infarction D. Pericarditis E. Mitral Valve Prolapse ____3. Can cause the heart muscle to die due to lack of oxygen. ____4. Caused by an obstructed vessel in heart thrombus. ____5. Inflammation of pericardial sac due to viral or bacterial infection.
