Human Heart Anatomy | Chambers, Valves & Blood Flow

If you're preparing for the DAT, we have everything you need to succeed all in one place. Check out https://bootcamp.com/dat and try it for free today! In this lesson, we break down the four chambers, the major heart valves (tricuspid, pulmonary semilunar, bicuspid/mitral, aortic semilunar), and the full pathway of oxygenated vs. deoxygenated blood through the pulmonary and systemic circulations. ► What you’ll learn • The heart’s role as the pump of the circulatory system • 4 chambers: right/left atria and ventricles (functions + differences) • How the tricuspid and pulmonary semilunar valves coordinate on the right side • How the bicuspid/mitral and aortic semilunar valves coordinate on the left side • Superior vs. inferior vena cava; pulmonary artery vs. pulmonary vein • Complete blood‑flow pathway and common DAT exam traps ⏱️ Timestamps 00:00 Intro & learning goals 00:21 The heart as the pump 00:57 Four chambers (overview) 01:55 Right atrium: deoxygenated blood 02:39 Venae cavae (SVC & IVC) 03:46 Heart valves & one‑way flow 04:03 Tricuspid (right AV) valve 04:51 Right ventricle → pulmonary artery 05:13 Pulmonary semilunar valve 06:33 Valve coordination (contract vs. relax) 07:35 Left side begins (purpose & overview) 07:58 Left atrium & pulmonary veins 08:41 Bicuspid/Mitral (left AV) valve 09:33 Left ventricle & aorta 10:49 Pulmonary vs. systemic circulation 11:08 Pulmonary flow: full path 11:53 Systemic flow: full path 12:15 Mini‑quiz (prompt) 12:40 Mini‑quiz answer (Tricuspid) 13:31 Wrap‑up Click here to build your personalized DAT study plan that fits your schedule: https://bootcamp.com/dat/aris-study-g...
