1. HEART AND CIRCULATION Session 34

2. OBJECTIVES  Describe the structure of the heart and its anatomical orientation (valves, muscles, tendinous cords, wall thicknesses, fibrous skeleton)  Compare and contrast the structure of the blood vessels throughout the body  Describe the blood and neural supply of the heart and the mechanisms involved in each  Identify the 3 most common sites of occlusion in the coronary arteries

17. STRESS TEST

18.  Groups of 3 (count off)  Assign a topic to each person:  Types of arteries and key features,  Types of veins and key features,  Thoracic and Abdominal aorta and Inferior Vena Cava (major branches, relationships, and locations)  Research independently for 5 minutes (all topics!)  Teach your group your assigned topic (5 minutes each)  Find weaknesses in peers’ knowledge by asking questions  Be respectful and keep the tone academic – no need to get personal  Information in the notes section is your guide for this material
