mechanism by which
atherosclerosis causes
problems in the
cardiovascular system?

and clot formation b)
through temporary

, c) ischemic stoke caused by restriction in blood supply
while hemorrhagic is caused by rupturing of a blood vessel
what is the primary
difference between
ischemic and
hemorrhagic stroke?
a) ischemic stroke
onlyoccurs in elderly while
hemorrhagic can occur at
any age
b) ischemic stroke
istreatable while
hemorrhagic is always fatal
c) ischemic stoke
causedby restriction in
blood supply while
hemorrhagic is caused by
rupturing of a blood vessel
d) ischemic stroke
affectsthe heart while
hemorrhagic affects the
brain
what is the formula for a) Co = stroke volume x heart rate
calculating cardiac output
(CO)?
a) Co = stroke
volume xheart rate
b) Co = heart rate
xblood vessel radius c) Co
= total blood volume x
heart rate
d) Co = mean arterial
pressure x total
peripheral resistance

deterioration
pathophysiology of
congestive heart failure?
a) heart failing as a
pumpwith compensatory
mechanisms that lead to
short-term improvement
but long-term deterioration
b) restriction in
bloodsupply to brain tissues
causing neurological deficits
c) inflammation of
heartvalves due to bacterial
infection
d) sudden occlusion
ofcoronary arteries leading
to myocardial infarction
what is the significance of c) it develops as an alternative blood supply route
collateral circulation in
relation to myocardial
infarction?
a) it leads to heart
valve
damage
b) it increases the risk
ofarrhythmia
c) it develops as
analternative blood supply
route
d) it causes
plaquerupture and clot
formation
