About the video

This educator explainer video was made with ngram to walk through the structure and function of the heart and circulatory system. the video covers the two divisions of circulation, pulmonary circulation that carries deoxygenated blood to the lungs for gas exchange, and systemic circulation that delivers oxygen and nutrients to body tissues. it examines the heart's location, orientation, and anatomical surfaces, including the base, apex, and sternocostal surface, and explains the pericardium's fibrous and serous layers that reduce friction and limit excessive movement. the lesson finishes with the three layers of the heart wall, the epicardium, myocardium, and endocardium, describing each layer's role in protecting and powering the heart. the content is organized as a clear anatomy lesson suited to medical students, anatomy learners, and healthcare professionals reviewing cardiovascular fundamentals.
