Tricuspid Valve
Prevents backflow from the right ventricle to the right atrium
Mitral Valve
Prevents backflow from the left ventricle to the left atrium
Pulmonary valve
Prevents backflow from the pulmonary artery to the right ventricle
Aortic valve
Prevents backflow from the aorta to the left ventricle
Put the correct order of blood flow through the heart.
Right atrium
Right ventricle
Pulmonary arteries and veins
Left atrium
Left ventricle
Pericardium
A double-walled sac that surrounds the heart
Endocardium
The endothelial membrane that lines the chambers of the heart
Myocardium
The middle layer of the heart wall; composed of cardiac muscle
Epicardium
The serous membrane on the surface of the myocardium
The point of maximum impulse of the heart is at the:
mediastinum
apex
base
aorta
The portion of the heart wall that lines the heart's chambers is the
myocardium
pericardium
endocardium
epicardium
Which heart valve controls the flow of blood between the left atrium and the left ventricle?
Pulmonary valve
Aortic valve
Tricuspid valve
Mitral valve
What is the name of the great vessel that supplies blood to the right atrium?
Superior and Inferior vena cavae
Aorta
Pulmonary arteries
Pulmonary veins
How does the myocardium receive its blood supply?
It receives its supply of blood from the left ventricle.
It receives its blood through the coronary sinus.
It doesn't require any additional blood other than what flows through the chambers.
It receives its blood through the right and left coronary arteries.
What is the heart's primary pacemaker?
The atrioventricular (AV) node
The Purkinje fibers
The sympathetic nervous system
The sinoatrial (SA) node
On an electrocardiogram, the QRS complex represents:
atrial depolarization
ventricular depolarization
ventricular repolarization
impulse transmission from the atria to the ventricles
On an electrocardiogram, the P wave represents:
atrial depolarization
ventricular depolarization
ventricular repolarization
impulse transmission from the atria to the ventricles
On an electrocardiogram, the T wave represents:
atrial depolarization
ventricular depolarization
ventricular repolarization
impulse transmission from the atria to the ventricles
The cardiac cycle is:
the amount of blood pumped by the heart in 1 minute
the heart's ability to beat spontaneously
the period when the left ventricle ejects its volume of blood
the series of events that occur from the beginning of one heartbeat to the beginning of the next
Cardiac output equals:
heart rate times stroke volume
stroke volume times ejection fraction
age times heart rate
the percentage of blood ejected by the ventricles with each contraction
The parasympathetic nervous system sends impulses to the heart via the vagus nerve, which:
slows the heart rate
increases the heart rate
doesn't affect the heart rate
raises the blood pressure, which, in turn, slows the heart rate
What is the term used to describe the amount of tension, or stretch, in the ventricular muscle just before it contracts?
Contractility
Afterload
Ascites
Preload
How big is your heart?
About the size of your brain
About the size of your lungs
About the size of a cell
About the size of your fist
How are arteries and veins different?
One is bigger than the other.
The arteries carry more blood than the veins.
The arteries carry blood away from the heart.
Veins carry blood to the heart.
The veins carry blood away from the heart.
Arteries carry blood to the heart.
Which chamber in the heart collects oxygen poor blood?
Right Atrium
Right Ventricle
Left Atrium

Which chamber in the heart collects oxygen rich blood?
Right Atrium
Left Ventricle
Left Atrium
Right Ventricle
Which chamber in the heart pumps oxygen poor blood to the pulmonary artery?
Right Ventricle

pulmonary
descending
coronary
carotid
What is Heart Failure?
heart attack
the heart stops beating
the heart has the inability to pump enough blood to meet the body's oxygen or nutrients needs
the heart fills with blood but it unable to pump any blood to the lungs or body

aortic and pulmonary
bicuspid and aortic
tricuspid and pulmonary
Prevention of backflow is the function of the
pulmonary arteries
valves
septums
vena cava
The circuit that delivers blood to the body is called
pulmonary
systemic
Blood vessels of the heart that supply blood to the heart
Coronary arteries
