Front Back
pericardium
the membrane that surrounds the heart; made of fibrous layers
apex of the heart
the tip of the heart
base of the heart
the side in which the heart rests; rests on the diaphragm
auricular flaps
2 flaps that point to the fron of the heart that represent the anterior wall of the atrium
superior vena cava
main vein that brings deoxigenated blood to the right atrium; brings blood from the upper part of the body
inferior vena cava
main vein that brings deoxygenated blood to the right atrium of the hear; comes from lower parts of the body
pulmonary trunk
large artery that carries deoxygenated blood from the right ventricle of the hear to the lungs
left and right superior and inferior pulmonary veins
4 veins that come back from the lungs and bring oxygenated blood to the left atrium of the heart
aorta
main artery that leaves the heart by the left ventricle and takes oxygenated blood throughout body
coronary circulation
circulation of blood in the heart itself
right coronary artery
comes off the aorta and moves down the right side of the heart
left coronary artery
comes off the aorta and moves along the front of the heart
marginal artery
branches off the right coronary artery on the front and goes along the base of the heart
posterior interventricular (descending) coronary artery
branches off the right coronary artery and curves around to the back of the heart
anterior interventricular (descending) coronary artery
branches off the left coronary artery and goes along the front of the heart; known as widow maker
circumflex artery
branches off the left coronary artery and goes around to the back of the hear
cardiac infarct
death of cardiac muscle
smallest cardiac veins
small veins that come out of the heart and perforate into the right atrium directly
small cardiac vein
runs in the same direction as the marginal artery, on the right side of the front of the heart; goes around to the back of the heart
middle cardiac vein
branches off the small cardiac vein on the back of the heart and runs in the same direction as the posterior descending cardiac artery
great cardiac vein
on the front of the hear; follows the same pathway as the anterior interventricular coronary artery.
coronary sinus
big union of veins where the small, middle, great, and marginal cardiac veins flow into. It brings deoxigenated blood to the heart from the heart itself
musculi pectinati
front wall of the heart only found in the auricular part of the atrium
cirstae terminales
the beoundary between the atria proper and the auricle.
fossa ovalis
little depression in the smooth wall of the right atrium of the heart that closes at birth; in the fetus it is a hole important in fetal circulation
tricuspid valve
valve between the right atrium and right ventricle that prevents backflow of the blood into the atrium once it passes to the ventricle
chordae tendinae
tendonous strings that attaches the cusps of the tricuspid valve to the papillary muscle on the ventricle
papillary muscle
found in the right ventricle; attached to cusps of triscuspid vale through cordae tendinae; when this muscle contracts, it pulls the tendinae, which opens the valve, letting blood in.
tuberculae carni
rideges on the interior walls of the ventricle
moderator band (septomarginal trabecula)
ridge of muscle tissue that goes form the interventricular septum to the anterior wall
pulmonary semilunar valve
guards the exit of the right ventricle; opened by blood pressure; leads into pulmonary trunk
mitral (bicuspid) valve
valve between the left atrium and ventricle. controlled by papillary muscle
aortic semilunar valve
valve in the left ventricle leading into the aorta. controlled by blood pressure
bracheocephalic (innominate) artery
branches off the aorta and divides into the right subclavian artery and the right common carotid
right subclavian artery
branches off the bracheocephalic artery and goes down upper extremity
right common carotid artery
branches off the bracheocephalic artery and goes up to the neck and head
left common carotid
branches off from the aorta (doesn't have bracheocephalic artery on the left side) and goes to the neck and head
left subclavian artery
branches directly off the aorta, goes down upper extremity
right vertebral thoracic artery
going through the transverse foramen of the cervical vertebrae; goes up to brain.
phrenic artery
goes to the diaphragm
right and left jugulars
veins that come down the neck. Combine with subclavian arteries to form innominate vein
innominate (bracheocephalic) vein
the two innominate veins, coming from the union of the subclavian and jugulars that go into the superior vena cava
thoracic duct
lymph vein that collects lymph from the abdomen and joins the left subclavian vein
