Definitions:

Aorta

The largest artery in the body, originating from the left ventricle of the heart and extending down to the abdomen, supplying oxygenated blood to the circulatory system.

Pulmonary Trunk

The major blood vessel transporting deoxygenated blood from the right ventricle of the heart to the lungs.

Pacemaker Potential

Pacemaker potential refers to the spontaneous gradual depolarization of the membrane potential in pacemaker cells, leading to the initiation of action potentials in certain heart cells.

SA Node

The sinoatrial node, often described as the heart's natural pacemaker, initiating the electrical impulses that set the pace for cardiac rhythm.
