30
Q

Separates the right and the left ventricles

A

Interventicular septum

31
Q

Partition that separates the right and the left atria

A

Interatrial septum

32
Q

receives blood supply thru the left and right coronary arteries, and coronary veins return the oxygen depleted blood from the heart muscle back to the heart.

A

Coronary circulation

33
Q

The force which was exerted by the blood on the walls of the vessel which is measured by the sphygmomanometer. The blood pressure is the difference between the systolic (pressure during contraction) and diastolic (pressure during relaxation).

A

Blood Pressure

34
Q

A rhythmic throbbing resulting from the alternating expansion and contraction of the artery

A

Pulse

35
Q

The average heart rate is 72 beats per minute (bpm) and the cardiac output refers to the volume of blood pumped per minute

A

Heart rate and cardiac output

36
Q

“lubb” which is the first sound as the ventricles contract or the AV valves close and “dupp” or the second sound which is heard when the semilunar valves close and the ventricles relax.

A

Origin of heart sounds

37
Q

Provides the graphical representation of the cardiac cycle’s activity

A

Electrocardiogram (ECG)

38
Q

Sends electric impulses throughout the myocardium which is initiated by the sinoatrial (SA) node (pacemaker)

A

Electrical conduction system

39
Q

Systole (contraction) & diastole (relaxation) which lasts about 0.8 seconds

A

Cardiac cycle

40
Q
