The Pacemaker of the Heart - SA and AV Nodes Made EASY!

The video explores the pacemaker potential in the heart's SA and AV nodes, explaining their roles in generating impulses that cause the heart to beat. It details the movement of ions like sodium, potassium, and calcium across cell membranes, leading to changes in membrane potential and the processes of depolarization and repolarization. The video also discusses what happens if the SA node malfunctions and how the AV node can compensate. It concludes with an interactive question to engage viewers in further discussion.
