The Heart’s Hidden Valves | Life’s Perfect Rhythm 🫀✨ . . . . 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 valves (

The conduction system of the heart is a specialized network of nodes and fibers that generate and transmit electrical impulses, allowing the heart to beat in a coordinated rhythm. This ensures efficient pumping of blood throughout the body. 🫀 Main Components of the Conduction System: 1. Sinoatrial (SA) Node – “The pacemaker of the heart” • Location: Right atrium (near the opening of the superior vena cava). • Function: Initiates electrical impulses that set the heart rate (normally 60–100 bpm).
