Questions and CORRECT Answers
The cardiovascular system consists of the heart, blood vessels, and blood. True, or false? -
CORRECT ANSWER - True
This layer of the heart consists of cardiac muscle tissue, and forms the bulk of the heart: -
CORRECT ANSWER - Myocardium
The inner lining of the heart is known as the: - CORRECT ANSWER - Endocardium
The lower chambers of the heart, the pumping chambers, are known as: - CORRECT
ANSWER - Ventricles
The upper chambers of the heart, which are smaller and receive blood, are known as: -
CORRECT ANSWER - Atria
As valves close, and blood hits those valves, heart sounds are created. We can hear those sounds
when we listen with a stethoscope. True, or false? - CORRECT ANSWER - True
These thin fibrous cords anchor the AV valves to the papillary muscles in the ventricles: -
CORRECT ANSWER - Chordae tendinae
There are 6 large veins carrying blood to the heart and 2 large arteries carrying blood away from
the heart. True, or false? - CORRECT ANSWER - True
There are 4 of these vessels, which carry oxygenated blood from the lungs to the left atrium of
the heart: - CORRECT ANSWER - Pulmonary veins
,After blood flows past the bicuspid valve, it next enters this chamber: - CORRECT
ANSWER - Left Ventricle
After passing through the tricuspid valve, a drop of blood would next enter this chamber: -
CORRECT ANSWER - Right ventricle
From the right atrium, a drop of blood would next pass through the: - CORRECT
ANSWER - Tricuspid valve
The circuit involving the right ventricle pumping blood to the lungs is the: - CORRECT
ANSWER - Pulmonary circuit
Which of the following is a long, high pressure circuit? - CORRECT ANSWER - Systemic
circuit
Both the intrinsic cardiac conduction system and the autonomic nervous system influence the
activity of the heart. True, or false? - CORRECT ANSWER - True
The portion of the cardiac conduction system found in the interatrial septum which acts to delay
the impulse is the _____. This delay allows the atria to contract before the ventricles do. -
CORRECT ANSWER - AV node
Which portion of the ECG is caused by depolarization of the atria? - CORRECT
ANSWER - P wave
The relaxation, or filling, phase of the cardiac cycle in known as: - CORRECT ANSWER -
diastole
During this low pressure phase, the semilunar valves close to prevent the backflow of blood into
the ventricles from the great vessels. The second heart sound is heard. - CORRECT
ANSWER - diastole
, How is cardiac output calculated? - CORRECT ANSWER - cardiac output equals heart
rate times stroke volume
The volume of blood pumped out by each ventricle in one minute is known as the: - CORRECT
ANSWER - cardiac output
The serous pericardium is like a: - CORRECT ANSWER - double layered water balloon
Based on your knowledge of cardiac anatomy & physiology, which of the following is true of the
1st heart sound, "lub" - CORRECT ANSWER - produced by closing the AV valves

CORRECT ANSWER - True
The wall between the 2 lower chambers is known as the: - CORRECT ANSWER -
Interventricular septum
Which chambers are more muscular? - CORRECT ANSWER - Ventricles
The atrioventricular valve which has 2 cusps is known as the _____ valve and is found between
the left atrium and the left ventricle: - CORRECT ANSWER - Bicuspid
These blood vessels branch off of the aorta and supply the heart muscle with oxygenated blood: -
CORRECT ANSWER - Coronary arteries
