B) medial to the sternum.
C) superior to the diaphragm.
D) posterior to the spinal column.
Q2
The apex of the heart
A) is part of the left ventricle wall.
B) points inferiorly and laterally.
C) is at the approximate level of the 5th
intercostal space.
D) All of the above are correct concerning the
apex of the heart.
Q3
In normal individuals, about 2/3 of the total
mass of the heart is located
A) above the aortic arch
B) on the right side of the thoracic cavity
C) on the left side of the thoracic cavity
D) in the right ventricle
Q4
A needle being inserted into the heart would travel
through the layers of the heart wall and coverings in
which order, beginning on the outside?
A) fibrous pericardium, parietal pericardium, visceral
pericardium, myocardium, endocardium
B) parietal pericardium, fibrous pericardium, visceral
pericardium, myocardium, endocardium
C) endocardium, myocardium, fibrous pericardium,
parietal pericardium, visceral pericardium
D) visceral pericardium, parietal pericardium, fibrous
pericardium, endocardium, myocardium
Pericardium
Fibrous pericardium tough, loose fitting
Serous pericardium 2 layers, few drops of
pericardial fluid between layers
Parietal layer
Visceral layer (epicardium)
Structure of heart
Epicardium
Myocardium contractile cardiac muscle cells
Endocardium endothelial tissue, form trabeculae
and valves

Q11
The chordae tendineae

B) prevent the atrioventricular valve cusps from prolapsing
into the atria during ventricular systole
C) open the atrioventricular valves during ventricular
systole
D) attach the heart to the pericardium
Q12
The heart valves
A) contract to pump blood through the heart.
B) separate the left and right sides of the heart.
C) prevent blood from flowing backward through
the heart.

left coronary artery?
A) left posterior ascending artery
B) circumflex artery
C) posterior interventricular artery
D) left subclavian artery
Q14

B) anterior walls of the left and right ventricles, and the
interventricular septum.
C) posterior walls of the left and right ventricles.
D) lateral walls of the right atrium and right ventricle.
