I. Circle T (True) or F (False). If the statement is false, cross out the word(s) that make it false
and write in an appropriate correction so that the statement now becomes a true statement.
T F 1. The wall of the femoral artery is thicker than the wall of the femoral vein.
T F 2. Most of the smooth muscle in arteries is in the tunica interna.
T F 3. Decrease in the size of the lumen of a blood vessel by contraction of smooth muscle is called
vasoconstriction.
T F 4. Cool, clammy skin is a sign of shock that results from sympathetic stimulation of blood vessels and
sweat glands.
T F 5. In its passage from an artery to a vein, a red blood cell must ordinarily travel through a capillary.
