ANS: C XK


The heart has four chambers: two atria and two ventricles. The right and left sides of t

he heart are separated by an internal wall of connective tissue called a septum. The in
XK XK XK XK XK XK XK XK XK XK XK XK XK XK XK

8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
XK XK XK XK XK XK XK XK XK XK XK XK XK XK XK


a. Left
b. Right
ANS: B XK


The job of the right side of the heart is to pump unoxygenated blood to and through
XK XK XK XK XK XK XK XK XK XK XK XK XK XK XK XK XK


the lungs to the left side of the heart. This is called the pulmonary circulation. The rig
