In the pulmonary circulation what is the correct order structures through which blood travels?
The property of the normal pacemaker region is able to provide a normal setting for the heart to beat. It allows the heart to beat at a regular rate.

The contraction of heart (cardiac) muscle in all animals with hearts is initiated by chemical impulses. The rate at which these impulses fire controls the heart rate. The cells that create these rhythmical impulses are called pacemaker cells, and they directly control the heart rate.
Pacemakers are set by the surgeon-physician at the time it is implanted. Most times, the pacemaker is simply set to a normal heart rate (around 70-80 beats per minute). The primary function of the pacemaker is to restore a more regular beat when the heart cannot maintain a normal heart rate. You should consult your physician-surgeon for particulars about your pacemaker, its use, function, and signs/symptoms to watch for after the pacemaker is implanted.

It keeps your heart at a steady pace.
The essential function that keeps the heart pumping is the contraction and relaxation of the heart muscle, which is controlled by electrical signals from the heart's natural pacemaker, the sinoatrial node.
An artificial pacemaker works by detecting changes in the heart's rhythm. If it detects a 'problem' - it delivers a shock to the heart's muscle - returning the heartbeat to a regular beat.
A pacemaker is nothing but a specialized mass of muscle tissue present in the wall of the heart. It initiates the heart beat.
