Practical 1 Flashcards
erythrocytes
red blood cells
fun- transport O2 to body and CO2 to lungs
lymphocyte
agran.
destroys foreign bodies and cancer/ virus
monocyte
agran.
Consume dead cells and other cellular debris
neutrophil
gran.
consumes bacteria
eosinophil
gran.
attack eukary. parasites
basophil
gran.
secrete histamine and heparin
vasodilator and anticogulant
thrombocyte
platelet
clots blood
Pericardial sac
Parietal pericardium
allows for elastic expansion and stability
outermost layer
epicardium
visceral pericardium
2nd outermost layer
protects and houses blood vessels
endocardium
innermost layer
lines heart chambers and covers valve surfaces
myocardium
middle layer (thickest) houses muscle vortex for contraction
L and R atrium
superior to ventricles
recieve blood from veins
auricles
expansion off atriums for inc. vol.
ventricles
inferior to atriums
pump blood out to arteries
coronary sulcus
seperates atriums from ventricles
interventricular septum
muscular wall btw ven.
tricuspid valve
Right side
3 cusps
btw atrium and ven.
bicuspid valve
left side
btw atrium and ven.
2 cusps
chordae tendineae
connect valve cusps to papillary musc. on floor of ven.
papillary muscles
prevent valves from flipping in or out
pulmonary semilunar valve
opening btw right ven. and pulmonary trunk
aortic semilunar valve
opening btw left ven. and trunk of aorta
pulmonary trunk and arteries
recives o2 poor blood from right ven. and transports blood to lungs
pulmonary veins
transport blood to left side of heart
infer. vena cava
drains diaphragm and below
superior vena cava
drains upper body
great cardiac vein
blood from anterior
empties into coronary sinus
coronary sinus
posterior side
empties into R atrium
right coronary artery
under r auricle
blood to r atrium
left coronary artery
under L auricle
blood to l atrium
cicumflex artery
blood to L atrium
anterior interven. artery (LAD)
blood to ventricles and 2/3 anterior side of interven. septum
posterior interven. artery (PDA)
blood to posterior interven. septum and wall of both ventricles
