Sentences with phrase «pacemaker cells»
"Pacemaker cells" refer to a special group of cells found in the heart that control the heartbeat. They generate electrical signals, or impulses, that tell the heart when to contract and pump blood. These cells are like the conductor of an orchestra, keeping the heart's rhythm in sync. Full definition
