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.
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.)
Tubes connected to the heart are called arteries and veins.
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.
Pulmonary veins
Arteries and veins are connected to your heart. The former carry blood from the heart, and the latter to the heart.
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.
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.
Every organ is connected to the lungs by blood vessels. The heart is directly connected.
your heart, lungs, arteries, and veins
The arteries carry blood away from the heart, and the veins to the heart. The main veins connected to the heart are the pulmonary vein and the vena cava, and the main arteries are the aorta and the pulmonary artery.
