Heart Flashcards
The 4 chambers of the heart
2 atriums (upper)
*right and left
2 ventricles (lower)
*right and left
The right side (chambers) are?
Pulmonary
* receives blood from the body and sends it to the lungs
The left side (chambers) are?
Systemic
* receives blood from lungs and sends it to the body
Circulation of right or the pulmonary side of the heart?
Superior Vena Cava / Inferior Vena Cava
Right Atrium
Tricuspid Valve
Right Ventricle
Pulmonary Valve
Pulmonary Artery
Circulation of left or the systemic side of the heart?
Pulmonary Veins
Left Atrium
Mitral Valve
Left Ventricle
Aortic Valve
Aorta
Heart wall layers
Endocardium
*deepest
Myocardium
*middle layer
Pericardium
*outer protective layer
2 major types of heart valve
Atrioventricular valves
Semilunar valves
4 valves in the heart
(Right)
Tricuspid valve
Pulmonary valve
(Left)
Mitral valve
Aortic valve
2 atrioventricular valves
R - AV valve : Tricuspid valve
L - AV valve : Mitral valve or bicuspid valve
2 semilunar valves

Branches of right coronary artery
-Right marginal arteries (acute marginal artery)
- Posterior interventricular artery. (in post. IV sulcus)
- Sinoatrial nodal artery.
- Atrioventricular nodal artery.
Branches of left coronary artery
- Left anterior descending
[LAD) or anterior interventricular artery.
(lies in anterior IV sulcus)
*Septal branches.
*Diagonal branches - Left marginal artery.
(Obtuse marginal artery) - Left circumflex artery.
Venous drainage of the heart
Superior vena cava
Anterior cardiac veins
Great cardiac vein
Small cardiac vein
Middle cardiac vein
Coronary sinus
Cardiac cycle events
Systole
Diastole
