CARDIOVASCULAR SYSTEM Flashcards
a muscular pump consisting 2 receiving chamber (atria) two pumping chambers (ventricles)
heart
apex anteriorly and inferiorly to the left at ______________
5th ICS, MCL
the heart is located in the _____ mediastinum
middle mediastinum
invaginated sac consisting of fibrous and serous
fibrous pericardium
tough covering
provide protection and anchors the heart into mediastinum
fibrous pericardium
two types of serous pericardium
parietal and visceral pericardium
outer layer of the serous pericardium membrane lines the fibrous coat
parietal pericardium
inner layer of the serous membrane
visceral pericardium
3 walls of the heart
EME
epicardium
myocardium
endocardium
external layer, the visceral layer of the serous pericardium
epicardium
middle muscular layer of the heart
myocardium
inner layer of the endothelium
endocardium
fibrous skeleton of the heart
surrounds the AV pulmonic, aortic valves
annulus fibrosis
fibrous skeleton between aortic and AV openings
fibrous trigones
fibrous skeleton of the heart
AFM
annulus fibrosis
fibrous trigones
membranous portion of the IV septa
structures separating the chambers
septa
separates the right and left atrium
interatrial septum
separates the right and left ventricles
interventricular septum
the right atrium receives blood from the
S, I, A, V, CS
superior vena cava
inferior vena cava
anterior cardiac veins
vena cordis minimae
coronary sinus
irregular muscular ridges probably to hold more blood
trabeculae carnae
conical in shape with the base attached to the ventricular wall and the apices receiving the end of the chordae tendinae
papillary muscles
thickest wall of the arteries
tunica media
thickest wall of the veins
tunica adventitia
the main arterial trunk of the systemic circularion
aorta
aorta divides into
AADA
ascending, arch, descending, abdominal
right coronary artery originates from right aortic sinus
left coronary artery originates from left aortic sinus
ascending aorta
direct branches of the ascending aorta
RCC, LCC
right coronary artery, left coronary artery
direct arch of aorta
BA, LCC, LS
branchiocephalic
left common carotid
left subclavian
branch that supplies the brain
left common carotid artery
begins at lvl 4 and descends to diaphragm to become abdominal aorta
descending aorta
lvl of T12
ends lvl L4
paired terminal branches
right common iliac, left common iliac
abdominal aorta
PAIRED VISCERAL OF THE ABDOMINAL AORTA
MSA, RA, T/O A
middle suprarenal
renal
testicular/ovarian
UNPAIRED VISCERAL ABDOMINAL AORTA
C, S&I M
coeliac artery
superior mesenteric
inferior mesenteric
PARIETAL PAIRED BRANCHES OF THE ABDOMINAL AORTA
IP, L, CI
inferior phrenic
lumbar
common iliac
UNPAIRED BRANCH OF THE ABDOMINAL AORTA
m.sac
median sacral
blood supply of the brain
ICA, V, CofW
internal carotid artery
vertebral artery
circle of willis
________________ becomes the popliteal artery that divides into
anterior tibial and posterior tibial artery
femoral artery
travelling pressure that causes an alternating expansion and recoil of elastic arteries
pulse
parasympathetic ____- nerve which is inhibitory to the heart
vagus nerve
