-
the greater the difference in the pressure, the
faster the fluid moved
-
someone with high blood pressure has a ___ flow rate
slower
-
flow of heart to tissue and back?
- heart
- blood flow (oxygenated)
- tissue
- deoxygenated blood flow
- heart
-
is directly proportional to differences in pressure
flow rate
-
why is adipose tissue highly vascularized?
it has a lot of blood vessels
-
the more blood vessels you have means that
the longer it will take for blood to get from point A to point B
-
adipose tissue related to fat people how?
bc obese people have high blood pressure bc theyre blood moves slower and has to work hard to get through the extra tissue
-
flow rate is indirectly proportional to the vessel length
F = 1/L
-
flow rate is directly proportional to the fourth power of the radius of the vessel
F= r4
-
branches off to form multiple arteries
aorta
-
small arteries branched from arteries
arterials
-
where are capillaries found
around tissue
-
come together to form veins
veinials
-
-
have the slowest blood flow
capillaries
-
velocity of blood flow goes from?
fast, slow, speeds up
-
to get more blood flow
vasodilate
-
which part has the highest total area
capillaries
-
the higher the area, the slower the
velocity
-
why is it important that blood flow slows down?
bc if it doesn't, then it doesn't give enough time for oxygen and nutrients to go in and out of the cell
-
aka layered blood flow
laminar flow
-
in laminar flow, which layer moves faster?
middle layer
-
where is laminar flow (continuous) found
in small blood vessels
-
when heart contracts and relaxes pushes increase in velocity in both directions
pulsatile
-
where do pulsatile blood flow occur?
at arteries between the heart and tissue
-
-
is not layered, opposite to laminar flow
turbulent flow
-
occurs after aortic and pulmonary valves or valves in veins
turbulent flow
-
found right next to the pumping chamber of the hear, vein between tissue and heart
turbulent flow
-
when blood flow is pushed through a valve then it is
turbulent
-
what are blood vessels made of
smooth muscle and connective tissue
-
change in volume inside blood vessels as a result of change in blood pressure
compliance
-
are veins or arteries more compliant?
veins
-
___ is always bigger than ___
-
artery vs vein, which has thinner wall?
vein
-
artery vs vein, yields more and requires less pressure to pull apart
vein
-
artery vs vein, is 24x more compliant
vein
