the cardiovascular sys-
tem?
2. About how much does Less than a pound and the size of a fist
the heart weigh and
what is it's size?
3. Mediastinum Space between the lungs where the heart lies
4. Apex The pointed end of the heart that rests on the diaphragm (it is directed
toward the left hip)
5. Base Top part of the heart that is broad
6. Pericardium Double-walled sac that the heart sits in and contains serous fluid be-
tween the layers to prevent friction
7. Pericarditis Inflammation of the pericardium that results in the decrease in the
serous fluid

body
20. How many valves are 4
contained within the
heart?
21. What is the purpose of Allows blood to flow in only one direction through the heart chambers
the valves? (from the atria through the ventricles)
