Aortic Valve

A

Structure in aorta that prevents blood from flowing backwards

21
Q

Chordae Tendinae

A

Cords that attach to papillary muscle

22
Q

Interventricular Septum

A

Separates ventricles

23
Q

Interatrial Septum

A

Separates Atria

24
Q

Papillary Muscle

A

Attached heart wall to cordae tendinae

25
Apex
The inferior tip of the heart
26
Coronary Sinus Opening
Blood from the coronary sinus enters the right atrium via this opening
27
Fossa Ovalis
Closed in adults; located within the interatrial septum
28
Coronary Artery (R/L)
Vascularizes the myocardium
29
Coronary Sinus
Collects venous blood from coronary veins and empires into the right atrium through the coronary sinus opening
