The document discusses the venous drainage system of the upper limb. It begins by describing the progression from venules to veins. It then notes that the upper extremity veins are divided into superficial and deep groups, with flow generally going from superficial to deep. A key distinction between veins and arteries is that veins contain valves to direct blood flow back toward the heart. The major veins that drain the upper limb are the cephalic vein and basilic vein, which drain into the subclavian, brachiocephalic, and jugular veins.

❑ An important structural distinction found in veins and not
present in arteries is valves.
