Identify the component of the heart’s electrical conduction system that fits each description below: Establishes the basic heartrate:  Delays action potential, letting the atria and ventricles contract separately: Conduct action potential through interventricular septum:  Directly brings action potential to contractile cells of the heart:

Explain why listening to the heart sounds can be clinically important.  In other words, what can this tell you about how the heart is functioning?

Describe the anatomy and physiology of the heart and circulatory system and the importance of healthy heart function.

What does Sinus rhythm mean? Provide a definition.    Name each wave form and describe what is happening electrically in the heart at each point.

Explain intrinsic conduction system, pertaining to organ level in the heart.

Trace the pathway of blood through the heart. List, in the order that blood flows, the names of the vessels entering and exiting the heart, name of the chambers of the heart, and name the heart valves.

By hand, diagram the blood flow from the heart to the capillaries and back to the heart.  Include chambers, various vessels, etc.

What is the tissue type for the following structures of the heart Fibrous pericardium Serous pericardium Myocardium Endocardium Right atrium right Ventricle Left Atrium  Left Ventricle Auricles  Papillary muscles Fossa Ovalis Pectinate Muscles Chordae Tendinae  Interventricular septum Tricuspid, pulmonary, Bicuspid, mitral, and Aortic semilunar valves pulmonary trunk Pulmonary artery Aorta Arteries Sinus/veins

Describe the path of an electrical impulse through the conduction system of the heart; describe the purpose of this electrical activity.

Clinical Corner: In speaking with his cardiologist, a high risk individual with angina pectoris during exercise was informed that his coronary blood flow is reduced. The most important variable that determines resistance to blood flow in his blood vessels is most likely:     increased viscosity of blood from not exercising.     the length of the blood vessel as he is a short individual.     the diameter of the vessel due to coronary artery disease.     increase blood pressure due to hypertension.
