Vein Blood vessel that carries deoxygenated blood (blood without oxygen, full of carbon dioxide) back to the heart; has a thin wall because the blood has a lower pressure
Capillary Very small blood vessels with very thin walls in which materials (oxygen, glucose, carbon dioxide) are exchanged between the blood and the body's cells
Plasma Part of the blood that is mostly water, but also has sugar, fats, and protein
