The Flow of Blood Thought the Body
Blood Vessels
Blood Vessels
• Blood travels through
your body in hollow
tubes called blood
vessels.
• 3 types
• Artery
• Capillaries
• Veins
Arteries
• Carry blood away from
the heart.
• Arteries have a thick wall .
• Each heart beat pumps
blood into your arteries at
high pressure.
• This is your blood
pressure.
• Oxygen rich blood
Capillaries
• Is a tiny blood vessel
that allows Oxygen to
enter body cells and
Carbon Dioxide to leave
cells.
• Exchange is crucial for
cells life
Veins
• After leaving the
capillaries blood enters
the veins and is brought
back to heart.
• Oxygen poor blood
