Aorta

17
Q

the part of the cardiovascular system which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.

A

Systemic circulation

18
Q

valve between an atrium and ventricle of the heart

A

Atrioventricular valve

19
Q

the valve between the left atrium and left ventricle of the heart, consisting of two triangular flaps of tissue.

A

Bicuspid Valve

20
Q

valve that is situated at the opening of the right atrium of the heart into the right ventricle.

A

Tricuspid valve

21
Q

strong, fibrous strings attached to the leaflets (or cusps) of the heart on the ventricular side

A

Chordae Tendineae

22
Q

each of a pair of valves in the heart, at the bases of the aorta and the pulmonary artery, consisting of three cusps or flaps that prevent the flow of blood back into the heart.

A

Semilunar valves

23
Q

prevents the blood from flowing back into the right ventricle.

A

Pulmonary aortic semilunar valves

24
Q

an artery supplying blood to the heart.

A

Coronary arteries

25
Q

runs in the coronary sulcus between the right atrium and ventricle and opens into the right extremity of the coronary sinus.

A

Cardiac veins

26
Q

a wide venous channel about 2.25 centimeters in length that receives blood from the coronary veins and empties into the right atrium of the heart.

A

Coronary sinus

27
Q

a condition marked by severe pain in the chest, often also spreading to the shoulders, arms, and neck, caused by an inadequate blood supply to the heart.

A

Angina pectoris

28
Q

another term for heart attack.

A

Myocardial infarction

29
Q

a small body of specialized muscle tissue in the wall of the right atrium of the heart that acts as a pacemaker by producing a contractile signal at regular intervals.

A

Sinoatrial node

30
Q

controls the heart rate

A

Atrioventricular node

31
Q

networks of fibers that receive conductive signals originating at the atrioventricular node (AVN), and simultaneously activate the left and right ventricles by directly stimulating the ventricular myocardium.

A

Purkinje Fibers

32
Q

a small device that’s placed in the chest or abdomen to help control abnormal heart rhythms.

A

Pacemaker

33
Q

an inadequate blood supply to an organ or part of the body, especially the heart muscles.

A

Ischemia

34
Q

very rapid irregular contractions of the muscle fibers of the heart resulting in a lack of synchronism between heartbeat and pulse

A

Fibrillation

35
Q

the phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries.

A

Systole

36
Q

the part of the cardiac cycle when the heart refills with blood following systole.

A

Diastole
