c. four; two yh
d. four; three yh
ANSWER: C y h
The heart has four chambers: two atria and two ventricles. The right and left sides of the hearta

7. Stimulation of alpha1 receptors results in yh yh yh yh yh .
a. increased heart rate yh yh
b. peripheral vasoconstriction yh
c. constriction of bronchial smooth muscle yh yh yh yh
d. increased force of myocardial contraction yh yh yh yh
ANSWER: B y h
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs.
