Which of the following is true regarding arteries and veins? (A) $\quad$ Arteries are thin-walled, muscular, and elastic, whereas veins are thick-walled and inelastic. (B) $\quad$ Arteries always conduct oxygenated blood, whereas veins always carry deoxygenated blood. (C) $\quad$ The blood pressure in the aorta is always higher than the pressure in the superior vena cava. (D) $\quad$ Arteries facilitate blood transport by using skeletal muscle contractions, whereas veins make use of the pumping of the heart to push blood.
