The heart is divided into(11) parts/chambers.
four
This statement is incorrect. The heart is divided into 4 chambers, namely the right atrium, left atrium, right ventricle and left ventricle. The right and left atria are the chambers at the top of the heart that receive blood from the body and lungs respectively. The right and left ventricles are the chambers at the bottom of the heart that pump blood out to the lungs and body respectively. The four chambers of the heart are separated by walls of muscle called septa.
