Close Up of a Beating Heart | (Full) 🫀 . . . . . . . . . . . . . The human heart is a vital organ that pumps blood throughout the body, supplying oxygen and nutrients while removing carbon dioxide and waste products. Here are some key points about the human heart: Anatomy: The heart has four chambers: two upper atria and two lower ventricles. The right side pumps deoxygenated blood to the lungs, while the left side pumps oxygenated blood to the rest of the body. Valves: There are four main valv

The heart beats with perfect rhythm — thanks to its own electrical conduction system. It starts at the sinoatrial (SA) node — the heart’s natural pacemaker — which generates impulses that spread through the atria. The signal slows at the atrioventricular (AV) node, then travels through the bundle of His, down the bundle branches, and into the Purkinje fibers, triggering coordinated ventricular contraction. This animation highlights the heart’s conduction system in motion. Based on SciePro’s 3D a
