or more inches of tubing and a Luer-Lok or vacuum tube holder connector; sometimes
called a "butterfly" set
capillary - ANS-a minute blood vessel that connects the smallest arteries to the smallest
veins and serves as an oxygen exchange vessel
capillary action - ANS-the action by which a fluid enters a tube because of the attraction
between the fluid and the tube
