Of course Dummies, How can you breathe if they weren't connected?
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
The tubes connected to the heart are the arteries and veins. Veins carry blood to the heart, and arteries carry blood away from the heart.
Blood vessels that carry blood from the heart to different organs are called arteries.Blood vessels that carry blood to the heart are called veins.
Tubes connected to the heart are called arteries and veins.
Pulmonary veins
veins from the body or the pulmonary veins from the lungs
Veins are where you will find deoxygenated blood that is returning to the heart to be sent to the lungs.
Arteries and veins are connected to your heart. The former carry blood from the heart, and the latter to the heart.
The pulmonary veins are high in oxygen and carry blood to the heart. The heart will then pump it to the rest of the body.

The heart receives blood from the lungs on the left side through the Pulmonary Veins.
The pulmonary veins carry blood from the lungs back to the heart.
