Veins
Vessels that carry blood to the heart
Arteries
Vessels that carry blood away from the heart
Capillaries
Site where O2 and CO2 are exchanged, tiny vessels connecting arteries to veins.
Oxygen rich blood/oxygenated
Blood that is high in O2 and low in CO2 (RED)
Oxygen poor blood/deoxygenated
Blood that is low in O2 and high in CO2 (BLUE)
Left Atrium
Receives O2 rich blood from the lungs

7. Receives O2 poor blood from the body
Right Atrium
Receives O2 poor blood from the body
Left Ventricle
Pumps O2 rich blood to the body
Right Ventricle
Pumps O2 poor blood to the lungs
Valves
Open and close to keep blood moving in one direction
Pulmonary Artery
Carries O2 poor blood to the lungs
Aorta
Carries O2 rich blood to the body
Pericardium
Thin sac (membrane) that surrounds the heart
