|
|
Serous membrane enclosing heart
|
visceral pericardium(epicardiun)
parietal paricardium(not part of heart) |
|
|
Heart Chambers
|
atrium, ventricles, septum
|
|
|
Septum
|
seperation between heart chambers
Interratrial septum sterventricular septum |
|
|
coronary arteries
|
branch from aorta
|
|
|
cardiac veins, coronary sinus
|
emties into right atrium
|
|
|
atrioventricular valves
|
between atria and ventricles
|
|
|
Left atrioventricular Valve
|
mitral or bicuspid
|
|
|
Right arioventricular Valve
|
Tricuspid
|
|
|
Chordae tendinae
|
collagenous cord that anchor tips of heart valves to ventricular wall
|
|
|
Papilary Muscle
|
small bundles of cardiac muscles that anchor chordae tendinae
|
|
|
semilunar valves
|
between ventricles and arteries
|
|
|
pulminary semilunar valve
|
Right ventricle
|
|
|
Aortic semilunar valve
|

|
|
Heart: Double Pump
|
1.Pulminary circuit
2. Systemic Curcuit |
|
|
Pulminary Circuit
|
gets blood from the body, pumps blood to lungs
|
|
|
Systemic circuit
|
Gets blood from lungs, brings to the entire body
|
|
|
Deoxyenated blood gets to heart through
|
Inferior and superior Vena Cava, and coronary Sinus
|
|
|
Myocardium
|
heart muscle.
|
|
|
right and left coronary arteries
|
branch from aorta and provide blood to myocardium
-after passing through cappilary beds in the myocardium , blood is collected by cardiac veins, this blood empties into coronary sinus, which finally empties into right atrium |
|
|
Arteries
|
always carry blood away from heart
|
|
|
Veins
|
Carry blood to heart
|
|
|
pulminary trunk
|
has right/left side to go to both lungs
-comes from R ventricle- |
|
|
Pulminary veins
|
brings oxygenated blood from lungs to hear(right and left side, 2 tubes)
|
|
|
three layers of heart
|
epicardium(visceral pericardium)
myocardium endocardium |
