Question

The right and left sides of the heart are completely separated by a wall, or _______.
A) pericardial cavity
B) thorax
C) septum
D) auricle

Accepted Answer

The right and left sides of the heart are completely separated by a wall called the septum. This separation prevents the mixing of oxygenated and deoxygenated blood. The pericardial cavity is a sac that surrounds the heart. The thorax is the part of the body that contains the heart and lungs. The auricle is an extension of the atria that helps increase the capacity of the atria to hold blood.
