Arteries always carry blood away from the heart. Veins always carry blood back to the heart.
Not all arteries carry high O2 blood. Not all veins carry low O2 blood.
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
A tadpole's circulatory system has one loop and a 2 chamber heart. Oxygen-poor blood goes to the heart from the blood vessels in the body. Then the oxygen-poor blood goes up from the heart through blood vessels in the lungs. Next it comes out as oxygen-rich blood and goes back to the heart. Finally the oxygen-rich blood goes into the blood vessels in the body.

The pulmonary veins carries oxygen rich blood from the lungs to the heart.
The heart and your blood vessels
coronary blood vessels.......
Blood veesels that are red are carrying blood that is rich in oxygen. Blood vessels that are blue are carrying blood that is oxygen poor. Red blood cells carry the oxygen, and they are the parts of the blood that turns red when carrying oxygen.
ARTERIES ALWAYS take blood AWAY from the heart.
Pulmonary artery
arteries carry oxygen rich blood out of the heart and veins carry oxygen deprived blood back to th heart
The arteries carry oxygen-rich blood away from the heart and to the rest of the body. Veins carry oxygen-poor blood back to the heart to be oxidized.
The vessels that carry blood to the heart are called veins and the vessels that carry blood away from the heart are called arteries.Arteries Always carry blood Away from the heart. Most are oxygenated except the pulmonary arteries which are low in oxygen and are going to the lungs to pick up oxygen.
