Blood transport system
- artery
- thick-walled blood vessels
carrying blood away from the
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
