It is divided into four chambers: two upper chambers and two lower chambers.## Step 2The two upper chambers of the heart are called the atria. They receive blood returning to the heart from the body and lungs.## Step 3The two lower chambers of the heart are called the ventricles. They pump blood out of the heart to the body and lungs.## Step 4The cardiac septum is a wall that separates the left and right sides of the heart.## Step 5The valves are structures within the heart that ensure blood flows in the right direction.## Step 6The pericardium is a double-walled sac containing the heart and the roots of the great vessels.
