Answer to Question 1

ANS: D
The superficial veins of the arms are in the subcutaneous tissue and are responsible for most of the venous return.

Answer to Question 2

ANS: A
Blood moves through the veins by (1) contracting skeletal muscles that proximally milk the blood; (2) pressure gradients caused by breathing, during which inspiration makes the thoracic pressure decrease and the abdominal pressure increase; and (3) the intraluminal valves, which ensure unidirectional flow toward the heart.
