heart
vein
thin-walled blood vessel
carrying blood towards
the heart
arterioles
small arteries
venules
small veins
capillaries
thin blood vessels supplying
nutrition to cells and
removing wast materials
pulmonory circulation
blood from the heart to the lungs
and back to the heart to pick up
oxogen
systemic circulation
oxygenated blood carried from
the heart to the body tissues and
back to the heart
vasoconstriction
reducing flow of blood into capillaries
by action of sympathetic nerves
vasodilation
is the increased flow
of blood into the
capillaries
venous return
the mechanisms that
return blood to the heart
skeletal pump
muscle actions that
squeezes veins and forces
blood towards the heart
respiratory pump
breathing moments force
blood to flow towards the
heart
haemoglobin
red pigment that transport
oxogen in the blood
oxyhaemoglobin
the chemical compound where
oxogen combines to
haemoglobin
bohr shift
the change of shape of the oxygen
dissociation curve, specifically a move to
the right which results in the releases of
more oxogen being released at the muscles
during exercise
hydrogen carbonate
main means by which CO2 is
transported by the blood
arterio-venous difference
amount of oxogen removed
from the blood by the muscles
