Heart and Circulation
- Important blood vessels in the heart
- Vena cava
- carries deoxygenated
blood
- from the body tissues
to the heart
- Pulmonary
artery
- carries deoxygenated blood
- from
the
heart
to the
lungs
- Aorta
- carries
oxygenated
blood
- from the
heart to the
body tissues
- Pulmonary vein
- carries
oxygenated
blood
- from lungs
to the
heart
- Circulation Path
- 1).Deoxygenated
blood enters the
vena cava
- 2).This blood enters the
right atrium, which then
proceeds to enter the
right ventricle
- 3).This then exits the heart
through the pulmonary artery,
to travel to the lungs
- 4).The blood re-enters the heart
through the pulmonary vein
- 5).Then, the blood enters the left atrium,
which then fills up the left ventricle
- 6).After that, the
blood exits through
the aorta, to give
blood to the rest of
the body
- Types of blood vessels
- Capillaries
- smallest vessel you have
- high pressure
blood flow
- carries blood away from
the heart
- Veins
- small, thin walls and less
muscle
- large amount of blood
- low pressure blood flow
- valves to prevent backflow
- Arteries
- thick walls and muscle
- carries blood away from the heart
- high pressure
blood flow
