2. What is the function of the fluid that fills the pericardial sac?
reduces friction on the beating heart
3. Match the terms in the key to the descriptions provided below. f a h e a g b d g c 1. location of the heart in the thorax 2. superior heart chambers 3. inferior heart chambers 4. visceral pericardium 5. “anterooms” of the heart 6. equals cardiac muscle 7. provide nutrient blood to the heart muscle 8. lining of the heart chambers 9. actual “pumps” of the heart 10. drains blood into the right atrium
Key: a. b. c. d. e. f. g. h. atria coronary arteries coronary sinus endocardium epicardium mediastinum myocardium ventricles
4. What is the function of the valves found in the heart?
prevents backflow, maintains one way direction through heart
5. What is the role of the chordae tendineae?
anchors cuspids to ventricle walls
Pulmonary, Systemic, and Cardiac Circulations
6. A simple schematic of a so-called general circulation is shown below. What part of the circulation is missing from this diagram? pulmonary circulation Add to the diagram as best you can to make
