You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/... • In this video, I take you through the structure of the human heart. First I explain to you the arrangement of the atria, ventricles, septum and atrioventricular valves. I then discuss the blood vessels leading in and out of the heart (the vena cava, the pulmonary artery, the aorta and the pulmonary vein) and how the blood flows through the heart. • Image credits: • Diagram of heart (modified) • https://commons.wikimedia.org/wiki/Fi... • National Heart Lung and Blood Institute (NIH), Public domain, via Wikimedia Commons • Heart model • https://commons.wikimedia.org/wiki/Fi... • BruceBlaus, CC BY-SA 4.0 https://creativecommons.org/licenses/..., via Wikimedia Commons
