THE PHYSIOLOGY OF HEART CAVITIES AND  FLOW CIRCULATION

How does blood travel through your heart and reach every part of your body? 🫀 In this video, we follow one single drop of blood through the complete cardiovascular circulation — from the body, into the right side of the heart, to the lungs, back to the left side of the heart, and finally out through the aorta to the rest of the body. You’ll learn: • The four chambers of the heart • The right and left sides of the heart • The superior and inferior vena cava • The tricuspid, pulmonary, mitral, and aortic valves • Why the pulmonary arteries carry oxygen-poor blood • How gas exchange happens in the lungs • Why the left ventricle has the thickest muscular wall • How blood travels through the pulmonary and systemic circulation • What happens when a heart valve does not work properly This video is designed for students, science learners, and anyone who wants to understand human biology more clearly.
