Cardiovascular Flashcards
People with O blood can accept __ blood
Universal donors, but can only accept O blood
What layer if the heart is composed of muscle
Myocardium
What segment if the ekg is associated with atrial systole
The P wave
does the heart need outside excitement
no, it is self exciting
process of 1st diastole
the blood enters the right atrium and passively passes through the right atrioventricular valve to the right ventrical
process of 1st systole
atrioventricular valves close, and the blood passes into the semi lunar pulmonary valve and proceeds to the lulngs
process of 2nd diastole
the blood moves into the left atrium and passively moves through the left atrioventricular valve into the left ventrical
process of 2nd stystole
blood moves from the left ventrical through the semi lunar aortic valve
where does the pulse from the SA node go
is it transmitted ot the ventricle through AV node which signals the ventricle to contract which initiates the first systole
what are capillary beds
a diffusion site for exchange between blood and interstitial fluid
what does a capillary bed consist of
a single layer of endothelial cells
what do capillaries merge into
venules which merge into veins
