A

In: from RA
Out: pulmonary arteries

27
Q

Semilunar valves

A

in Pulmonary arteries and aorta

28
Q

33
Q

Aortic vestibule

A

outflow part of LV

from Bulbous cordis

34
Q

Diastole

A

ventricles are relaxing and filling

AV valves open, semilunar closed

35
Q

Systole

A

Semilunar open, AV closed

high blood pressure, push blood out of heart

36
Q

Fibrocartilagenous tissue

A

surrounds valves, divides atria from ventricles, provides barrier between atrial and ventricles for conductive system, provides attachment for heart valves and myocardium

37
Q

Tendon of conus arteriosus

A

aortic ring attached to pulmonic ring

38
Q

Left fibrous trigone

A

attaches mitral valve to aortic semilunar valves

39
Q

Right fibrous trigone

A

attaches atrioventricular valves to aortic semilunar vlaves

40
Q

Valves to coronary arteries sit

A

in aortic semilunar valves, just above L & R cusps

41
Q

Right Coronary a.

A

longer of 2 arteries

branches into Nodal a., Marginal a., and Posterior interventricular a.

42
Q

Nodal artery

A

branch of right coronary a.

supplies SA node

43
Q

Right marginal a.

A

to apex, branch of R. coronary artery

44
Q

Posterior interventricular a.

A

sits in posterior interventricular groove

branch of right coronary a.

45
Q

Left coronary a.

A

branches right away into Circumflex and anterior interventricular (LAD) branches

46
Q

Circumflex a.

A

wraps around coronary sulcus toward r. coronary a.

47
Q

Left anterior descending a. (anterior interventricular)

A

in anterior interventricular groove, toward apex

48
Q

Coronary sinus

A

main vein, drains into right atrium

49
Q

Great cardiac vein

A

in front, in anterior interventricular groove with LAD

50
Q

Middle cardiac vein

A

in back, posterior interventricular groove

51
Q

Small cardiac vein

A

off side, runs with marginal a. on front

52
Q

Anterior cardiac veins

A

cross right coronary a., only veins that drain directly into RA, not coronary sinus

53
Q

Sinuatrial node

A

initiates impulse for contraction

junction of SVC and right atrium

54
Q

Atrioventricular node

A

in posteroinferior region of interatrial septum near coronary sinus
collects impulses from atria and distributes to ventricles through the AV bundle of His

55
Q

Cardiac plexus

A

sympathetics and parasympathetics (vagus)

Sympathetic chain T1-T5

56
