Nutrients, oxygen and wastes pass in and out of your blood through the capillary walls.Veins carry blood back toward your heart.rteries are blood vessels that carry oxygen rich blood away from the heart.

The circulatory system is big and complex. The basics are that generally arteries convey oxygenated blood, while veins carry deoxygenated blood. The left side of the pig conve â¦ ys oxygenated blood and the right conveys deoxygenated. The only exception to the artery vein rule is in the pulmonary artery and vein.he pulmonary artery then carries deoxygenated blood away from the left ventricle to the lungs. To start the right atrium conveys blood from the superior vena cava to the right ventricle.
