Answer to Question 1

ANS: C
The three layers of the arterial walls are the intima, media, and adventitia. The innermost layer is the intima (tunica intima), a single layer of endothelial cells on a thin matrix of hyaluronic acid, collagen, and elastic fibers. The middle layer is the media (tunica media, or yellow fibrous). The outermost layer is the adventitia (tunica adventitia, or white fibrous connective tissue).

Answer to Question 2

ANS: F
Pulmonary arteries carry deoxygenated blood to the lungs and the pulmonary veins carry oxygenated blood to the heart.
