Deoxygenated
blood
Blood containing a
low
concentration of
O2
Oxygenated
blood
Blood contains
high
level of
oxygen
Vena cava
Carried
deoxygenated blood
from the body into the
right atrium
Right atrium / right ventricle
Tricuspid valve-
opens and closes to prevent
backflow
Pulmonary vein
Receives deoxygenated blood from the
right
ventricle to take the
lungs
to prescience oxygen
lungs
where gaseous exchange occurs to turn
deoxygenated
blood onto
oxygenated
blood
Pulmonary vein
Brings
oxygenated
blood from the lungs to the
left
atrium
Left atrium / left ventricle
Bicuspid valve
- opens and closes to prevent
backflow
Aorta
Main arterty. carries oxygenated blood from the
left
ventricle to take
oxygen
to the working muscles
Blood vessels
Three main blood vessels
capillaries
veins
arteries
Arteries
Thick electic wall
small
internal diameter (lumen)
carries blood at
high
press
Veins
Thinner
putter wall
large
internal
diameter ( lumen)
contain
valves
to prevent backflow
Capillaries
extemely thing walls
allow
gaseous exchange
Vasoconstriction
Inner diameter will
narrow
to
reduce
blood flow to inactive areas
Vasodilation
Inner
diameter
widens to increase
blood flow
to the active areas
