A partition separating two chambers, such as that between the nostrils or the chambers of the heart is known as a septum.

A heart beat is the cycle of contraction of the heart muscle, during which the chambers of the heart contract. The beat begins with a rhythmic impulse in the sinoatrial node, which serves as a pacemaker for the heart. It involves two phase systole and diastole.
