⭐️ 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
