The primary blood vessels that transports deoxygenated blood from the heart to the lungs are

• Carotid Arteries

• Pulmonary Arteries

• Pulmonary Veins

• Superior Vena Cava

the right AV(atrioventricular) value is known as

• I dont know

• bicuspid value

• aortic semilunar value

• pulmonary semilunar value

Pulmonary veins

• I dont know

• split off the pulmonary truck

• transport oxygenated blood to the lungs

• return blood to the right atrium of the heart

• transport oxygenated blood to the heart

Blood leaving the heart may go to

• arties in the heart

• the lungs

• other parts of the body

• all above

How do the lungs help the heart in the circulatory system?

• They provide oxygen to deoxygenated blood

• they provide carbon dioxide to deoxygenated blood

• they provide oxygen to oxygenated blood

• they provide carbon dioxide to oxygenated blood.

The blood that enters the right side of the heart contains ------------- because it came from the body.

• Oxygen

• Nitrogen

• Carbon Dioxide
