ANS: s s D
The front (anterior) surface of the heart lies behind the

ANS: s s C
The heart has four chambers: two atria and two ventricles. The right and left

sides of the heart are separated by an internal wall of connective tissue called
s s s s s s ss s s s s s s s s s s s s s s s s s s s s
a septum. The interatrial septum separates the right and left atria. The
s s s s s s ss s s s s s s s s s s s s s s s s
interventricular septum separates the right and left ventricles. The septa separate
s s s s s s ss s s s s s s s s s s s s s s
the heart into two functional pumps. The right atrium and right ventricle make
s s s s s s s s s s s s s s ss s s s s s s s s s s
up one pump. The left atrium and left ventricle make up the other.
