pass to root of lung
vagus nerve
deoxy bloods passage
r. atrium
tricuspid valve
r. vent
pulm. valve
to lung
from lung (oxy)
l. atrium
mitral valve
l. vent
aortic valve
to body
each semilunar valve has
3 semilunar cusps
semilunar valve
have no chordae tendinae or papp muscle
RV to pulm art
pulm. valve
at left sternal border, 2nd intercostal space
pulm valve
aortic valve
L. vent to aorta
over r. sternal border, intercostal space
tricuspid valve
RA to RV
over left sternal border, 5th intercostal space
mitral valve
LA to LV
over 5th intercostal space,
midclav. line
fossa ovalis
remnant from foramen ovale
on atrial septum
dividing the l and r atria
fossa ovalis
anulis ovalis
upper most past of fossa
crista terminales
vertical ridge b/n vena cava orifice
SA node on
crista terminales
junction of sinus venosus and heart in
developing embryon
sulcus terminales
vert groove on ext heart represent crista terminales
pectinate m.
from crista terminales to atrial appendage
appendage of r. atrium
r. auricle
conduction system
SA, AV node
both innervated by PS fibers from CN X and
Symp. fibers from T1-4
Sa and Av node
pulmonic circulation
R. ventricle
pump deoxy blood from pulmonic vale to pulm art and lunf for oxygenation
r. vent
ridge of cardiac m. in ventricle
trab. carnae
chordae tendinae
thin tendnous cords from valve cusps to papp muscle
papp muscle
anchor chordae tendinae to heart valve
l. valve
apex of heart
auscultate 5th intercostal space at midclav line
–>systemic circ.
recieve O2 blood from lung and pump to rest of body
L. vent
out of aortic valve to aorta
l. vent
thicker than RV b/c of higrh after load from systemic circ.
L. vent
RV internal features
same as LV
pericardium
tough double covering of heart
phrenic nerve
pericardium
outer fibroud
par. pericardium
inner serous
visc. pericardium
coronary art
coronary ostia located withing aortic valver leaflets
drain to coronary sinus and drain back to RA
coronary art
coronary art
fill during diastole
ischemia (angina)
infarction(heart attak)
blockage of cor. art and disrupted plaque lead to
l. circumflex art supply
LV lat wall
l. ant desc. art
ant wall LV
and interventicular septum
R. coronary art
r. vent
av node
post inf wall of LV

continuation of great cardiac vein
open into r. atrium b/n IVC and tricuspid orifice
tf all veins drain to coronary sinus
