THE VENOUS SYSTEM The veins are the vessels returning the blood to the heart. As a rule, veins carry only impure blood, but the pulmonary veins returning blood from the lungs to the left auricle carry pure blood. After death the veins can readily be distin- guished from the arteries by the fact that they have much thinner walls than the ar- teries and are usually full of blood, while the arteries are empty (Fig. 76). This is. Fig. 76. Cross-section of Ar- tery and Vein. X 350. V, Vein ; A, artery ; en, inner coat; ep, epithelium lining the vessels; et, middle or muscular coat of vein ; ex, muscular coat of ar- tery; fb, fibro-areolar coat.ââ (From Martin's "Human ;) due to the fact that the thick muscular coat of the arteries, by its contraction tends to drive the blood into the veins, whose muscular coat is very thin. The three coats composing the walls of the veins are the epithelial, or tunica intima; the middle, or muscular;.
