c. left ventricle
d. right ventricle
ans: d
the front (anterior) surface of the heart lies behind the sternum and costal cartilages. it is formed
by portions of the right atrium and the left and right ventricles. however, because the heart is

d. stroke volume; peripheral vascular resistance
ans: c
blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.
obj: identify and explain the components of blood pressure and cardiac output.
