heart makeup
heart base
superior
heart apex
lower left
rt atrium
rt ventricle
lt atrium
lt ventricle
chambers of the heart
receives deoxy blood
rt atrium
pumps deoxy blood to lungs
rt ventricle
receives oxy blood from lungs
lt atrium
pumps oxy blood to circulatory system in body
lt ventricle
tricuspid valve
rt atrioventricular valve
valve between rt atrium and ventricle
pulmonary semilunar valve
valve between rt ventricle and pulmonary arteries
bicuspid
mitrol
lt atrioventricluar valve
valve between lt atrium and ventricle
aortic semilunar valve
valve between lt ventricle and ascending AO
3 layers
epicardium
myocardium
endocardium
heart wall
fibrous layer
serous layer
epicardial fat
pericardium
attaches to central tendon of diaphragm
pierced by IVC
fibrous pericardium
double layered sac membrane inside fibrous pericardium
serous pericardium
most commonly located at areas around in and out flow of the heart
epicardial fat
divides the left and rt ventricles
interventricular septum
divides the left and rt atrium
interatrial septum
hole between rt and lt atrium during fetal formation
closes after birth
foramen ovale
depression left after foramen ovale closes
fossa ovalis
ascending
arch
descending
partsof the aorta
rises out of left ventricle
ascending AO
turns from ascending AO to descending AO
3 branches off
AO arch
takes oxy blood to torso and lower extremities
descending AO
LT CCA (common carotid artery)
L subclavian
brachiocephalic trunk
branches off of AO arch
divides into 2 ateries to take deoxy blood to lungs
pulmonary trunk
divides into superior and inferior from lung, begins as capillary network in alveoli
takes oxy blood to Rt atrium (p.350)
rt pulmonary vein (pulmonary artery takes deoxy blood into lungs)
return oxy blood from lungs to lt atrium
2 rt
2 left
pulmonary veins
supply blood to heart itself
arise from base of ascending AO
coronary arteries
supply RA/RV (rite atrium/ventricle)
IA septum (interatrial)
IV septum (interventricular)
right coronary artery
supply LA/LV (left atrium/venticle)
IA septum (interatrial)
IV septum (interventricular)
left coronary artery
supplies heart muscles with blood,comes off of ascending aorta, left and right
coronary circulation (coronary artery)
main veinous drain for heart
coronary sinus
great cardiac V
small cardiac V
middle cardiac V
drain into coronary sinus
runs parallel to IVC
drains posterior torso
secondary blood flow if IVC becomes blocked
azygos venous system
internal/external jugulars
subclavian V
brachiocephalic V
tributaries to the SVC
drains all deoxy blood from lower body back to RA (rite atrium)
IVC

serratus superior/inferior
diaphragm

main muscle of respiration
diaphragm
crura
AO (aorta) hiatus
Caval hiatus
esophogeal hiatus
parts of the diaphragm

ascends toward the axillary region

subcutaneous
mammary
retromammary
layers of the breast

excretory ducts
suspensory (cooper’s) ligaments
mammary layer
tissue behind mammary layer
contains the pectoralis muscle
retromammary layer
embedded in connective tissue
gives breast size and shape
