What is the function of the cardiovascular system? - Correct
answer- Transportation
About how much does the heart weigh and what is it's size? -
Correct answer- Less than a pound and the size of a fist
Mediastinum - Correct answer- Space between the lungs where
the heart lies
Apex - Correct answer- The pointed end of the heart that rests on
the diaphragm (it is directed toward the left hip)
Base - Correct answer- Top part of the heart that is broad
Pericardium - Correct answer- Double-walled sac that the heart
sits in and contains serous fluid between the layers to prevent
friction
Pericarditis - Correct answer- Inflammation of the pericardium
that results in the decrease in the serous fluid

Myocardium
Endocardium
Endocardium - Correct answer- A thin sheet of endothelium that
lines the heart chambers, it is continuous with the linings of the
blood vessels (innermost layer of the heart wall)
How many hollow chambers does the heart has? - Correct answer-
4
Atria - Correct answer- Receiving chambers, blood comes into the
heart
Where are the atria located? - Correct answer- Superior
Ventricles - Correct answer- Bottom chambers that send out
blood
Interatrial or intraventricular septum - Correct answer- Divides
the heart longitudinally
Which side of the heart receives oxygen-poor blood from the
veins? - Correct answer- The Right Side
Superior and Inferior Venae Cavae - Correct answer- The veins
that bring in blood from the upper and lower parts of the body to
the heart
