d. A-V node, A-V bundle, Purkinje fibers, S-A node
13. The decrease in the speed of
conduction from the A-V node through
the A-V bundle results in:
a. failure of the ventricles to contract
b. adequate time for the ventricles to fill

d. a decrease in the rate of blood flow
from the atria to the ventricles
14. Blood flows from the pulmonary
veins into the:

the atria contract when they are
directly stimulated by the:
