Resource summary
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
