Plasma is the liquid part of the blood. Arteries are blood vessels that carry oxygen rich blood away from the heart. Capillaries are tiny blood vessels that connect arteries to veins. 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 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.The pulmonary vein, in this case, conveys oxygenated blood to the left atrium away from the lungs.n Open circulatory system is one in which the flow of blood/hemolymph is from the heart to the peripheral organs then to the body cavity. There is no system of veins to carry â¦ the blood back to the heart.
