Chapter 13: Cardiovascular System Review

Front

The cardiovascular system consists of all of the following except: the heart, the arteries, the veins.

Back

the lungs.

Front

The pulmonary circuit

Back

sends deoxygenated blood to the lungs.

Front

Which of the following represents the correct sequence of parts through which blood moves from the vena cava to the lungs? Right atrium, pulmonary valve, right ventricle, tricuspid valve, Right atrium, tricuspid valve, right ventricle, pulmonary valve, Tricuspid valve, right atrium, pulmonary valve, right ventricle, Pulmonary valve, right atrium, tricuspid valve, right ventricle

Back

Right atrium, tricuspid valve, right ventricle, pulmonary valve

Front

When the left ventricle contracts, blood passes into the

Back

aorta.

Front

When the ventricular walls contract, what happens to the bicuspid and tricuspid valves?

Back

bicuspid and tricuspid valves close.

Front

The correct sequence of parts that function to carry cardiac impulses is: SA node, AV node, AV bundle, Purkinje fibers.

Back

SA node, AV node, AV bundle, Purkinje fibers.

Front

In an ECG pattern, the P wave is caused by

Back

depolarization of the atrial muscle fibers.

Front

In an ECG pattern, the T wave is caused by

Back

repolarization of the ventricular muscle fibers.

Front

In an ECG pattern, the P-Q interval indicates how long it takes for the cardiac impulse to travel from the

Back

SA node to the Purkinje fibers.

Front

An abnormally slow heart rate is termed

Back

bradycardia.
