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.

A. As the heart contracts it forces blood into arteries which branch into smaller arteries that. branch to from smaller arterioles. Arterioles carry blood into capillaries (capillary beds) which. carry blood into body tissues. B. Blood returning from the capillary beds empties into venules that merge to form veins.Veins. ultimately empty into the heart. II.
