Q

Muscular protrusions that anchor the chordae tendinae to the ventricle wall

A

Papillary Muscles

17
Q

A cord that crosses the lumen of the right ventricle and is thought to prevent over distension of the right ventricle. It contains purkinje fibers that may act as an extension of the bundle branches in the conducting of electrical impulses

A

Trabecula Septomarginalis

18
Q

This semilunar valve is located at the junction of the right ventricle and the pulmonary trunk and prevents blood from flowing back into the ventricle.

A

Pulmonary Valve

19
Q

This semilunar valve is located at the junction of the left ventricle and the aorta

A

Aortic valve

20
Q

This valve is between the right atrium and the right ventricle. Is it bicuspid or tricuspid?

A

Right AV valve

Tricuspid

21
Q

This valve is between the left atrium and left ventricle. Is it bicuspid or tricuspid?

A
  • Left AV valve

- Bicuspid

22
Q

Large blood vessel that enters the right atrium

A

Vena cava

23
Q

Large blood vessel that enters the left atrium

A

Pulmonary Vein

24
Q

Large blood vessel that leave the right ventricle

A

Pulmonary artery

25
Q

Large blood vessel that leaves the left ventricle

A

Aorta

26
Q

What is the path of blood through the heart?

A
27
Q

The measurement area in an ECG that begins and ends on the isoelectric line and corresponds to depolarization of the left and right atria.

A

P wave

28
Q

The measurement area in an ECG that begins and ends on the isoelectric line from the start of Q wave to the end of S wave. It corresponds to depolarization of the left and right ventricles.

A

QRS complex

29
Q

The measurement area in an ECG that begins and ends on the isoelectric line that corresponds to repolarization of the left and right ventricles

A

T wave

30
Q

The measurement area in an ECG that is from the start of P wave to the start of the QRS complex. It represents the time of impulse conduction from the AV node to the ventricular myocardium.

A

P-R segment

31
Q

The measurement area in an ECG that is from the peak of an R wave to the peak of a succeeding R wave and represents the time between two successive ventricular depolarizations.

A

R-R segment

32
Q

On an ECG, where does ventricular systole occur?

A

From the peak of the QRS complex to just after the peak of the T wave

33
Q

On an ECG, where does ventricular diastole occur?

A

From just after the peak of the T wave to the beginning of the QRS complex

34
Q

What does ECG stand for and what does it measure?

A
  • Electrocardiography (electrocardiogram)

- Measures electrical and mechanical activity of the heart

35
Q

In an ECG, what is amplitude measured in?

A

mV
