ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL
a. Left
b. Right
ANS: B ZL
The job of the right side of the heart is to pump unoxygenated blood to and through the
ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL ZL Z
lungs to the left side of the heart. This is called the pulmonary circulation. The right side
