CHAPTER 4 CARDIOVASCULAR
SYSTEM (PATHOLOGY) QUESTIONS
AND ANSWERS | GUARANTEED PASS |
NEW
What does the cardiovascular system consist of - Correct Answer-
heart, arteries, capillaries, and veins
Cardiovascular system's two subsystems of circulation - Correct
Answer-pulmonary and systemic
Pulmonary circulation - Correct Answer-transports blood between
heart and lungs for exchange of blood gases
Systemic circulation - Correct Answer-transports blood between the
heart and the rest of the body
Portal system - Correct Answer-through the liver
Cardiac system - Correct Answer-through the heart
Coronary system - Correct Answer-to the heart muscle
Two upper chambers of the interior heart - Correct Answer-right and
left atria
Two lower chambers of the interior heart - Correct Answer-right and
left ventricles
Role of heart - Correct Answer-acts as a pump to propel the blood
throughout the body via circulatory vessels
Three tissue layers of the heart - Correct Answer-Endocardium,
myocardium, epicardium
1
, 2
Endocardium - Correct Answer-innermost smooth layer of the heart
with valves composed of endocardium
Myocardium - Correct Answer-middle, muscular layer of the heart. It
is the thickest layer which receives blood supply from right and left
coronary arteries
Epicardium - Correct Answer-The outermost layer that acts as a
protective covering
Pericardium - Correct Answer-Double walled membranous sac that
protects against friction & permits the heart to move freely during
contraction
Heart lies at an _____ plane with mediastinum - Correct Answer-
oblique
PA chest will demonstrate __/__'s of the heart to the _______ of the
midline - Correct Answer-2/3; left
Right side of heart is composed mainly of - Correct Answer-right
atrium
Left side of heart is composed mainly of - Correct Answer-left
ventricle
What position is useful in demonstrating right ventricle and left
atrium - Correct Answer-left
On a lateral chest, ________ ventricle is the anterior portion of the
cardiac shadow - Correct Answer-right
On a lateral chest, ________ ventricle and atrium make up the
posterior cardiac shadow - Correct Answer-left
The contraction of myocardium is termed - Correct Answer-systole
