⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The path of deoxygenated blood from the body to the lungs * Entry into the heart via the vena cava into the right atrium. * Passage through the right atrioventricular and semilunar valves. * Ejection from the right ventricle into the pulmonary artery towards the lungs. 2. The path of oxygenated blood from the lungs back to the body * Return to the heart via the pulmonary veins into the left atrium. * Passage through the left atrioventricular (bicuspid) and semilunar valves. * Ejection from the left ventricle into the aorta to circulate around the body. 3. The double circulatory system * An explanation of the pulmonary circuit (to the lungs). * An explanation of the systemic circuit (to the body). *** CHAPTERS *** 0:00 Introduction 0:03 Deoxygenated Blood Returns to the Heart 0:17 Pumping Blood to the Lungs 0:26 Oxygenated Blood Returns to the Heart 0:39 Pumping Blood to the Body 1:03 Pulmonary and Systemic Circuits #Biology #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE #IB #AP
