Unit 7 Cardiovascular System

CARDIOVASCULAR SYSTEM (aka Circulatory System) Learning Objectives

  1. Identify tissues that make up the cardiovascular system (CVS) and the characteristics of each – especially the features of cardiac muscle tissue.

  2. Name and identify the major organs of the CVS.

  3. Describe how blood flows through the heart (including the pulmonary, systemic and cardiac circuits) and each of the major blood vessels leaving/entering the heart (Be able to draw this!)

  4. Compare and contrast the anatomy of blood vessels including similarities and differences between arteries and veins and smaller blood vessels and how their structure relates to their function!

  5. Identify the name and function of the structures of the heart identified in lab including pericardium, interventricular septum, 4 different valves (2 types), endocardium, epicardium, myocardium, chordae tendinae, papillary muscles, ventricles, apex, aorta, pulmonary artery, left/right atria, and coronary artery.

  6. Explain how the two types of valves in the heart (semilunar vs atrioventricular) work differently

  7. Describe the cardiac conduction system in terms of its route and the rate at which each of those specialized cells conducts impulses (SA node, AV node, Purkinje fibers, etc.) and state the effects of the sympathetic and parasympathetic nervous systems.

  8. Describe the electrical activity of the heart as seen on an EKG (ECG) – describe what is happening in each of the waves that make up a cardiac cycle.

  9. Describe the causes of atherosclerosis and cardiovascular disease. Describe each of the following and their purpose in connection with cardiovascular disease: stents, angioplasty, cardiac bypass surgery and nitroglycerin tablets.
