2. What is the function of the fluid that fills the pericardial sac?
Fluid in the pericardial sac allows the heart to beat in a
relatively frictionless environment, to reduce friction during heart activity
3. Match the terms in the key to the descriptions provided below.

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
B D G C
4. What is the function of the valves found in the heart?
The valves enforce a one-way blood flow through the heart
chambers; and prevents back-flow of blood
5. What is the role of the chordae
