Physical EducationCardiovascular systemRespiratory systemGCSEAQA Created by: SamPackhamCreated on: 28-06-17 10:35 What is the circulatory system made up of? Heart, Blood Vessels and Blood. 1 of 23 What is the respiratory system made up of? Lungs and Airways. 2 of 23 What is the main function of the cardio-respiratory system? Breathing, pumping blood and oxygen around the body. 3 of 23 What are the parts involved in the respiratory system? Nose, mouth, trachea, intercoatal muscles, rib cage, brochi, bronchioles, lungs, diaphragm, alveoli and capillaries. 4 of 23 What happens between the alveoli and the capillaries surrounding it? Gaseous exchange occurs and reoxygenises the blood cells. 5 of 23 What does haemoglobin carry from the body? Carbon dioxide. 6 of 23 Haemoglobin and oxygen react together to create ... Oxyhaemoglobin. 7 of 23 What happens in your body when you inspire? Rib cage moves out, intercoastal muscles contract, lungs expand and the diaphragm moves down. 8 of 23 What happens in your body when you expire? Rib cage moves down and in, intercoastal muscles relax, lungs get smaller and the diaphragm moves up. 9 of 23 Tidal volume The normal amount of air inhaled or exhaled per breath. Tidal volume increases with exercise. 10 of 23 Expiratory reserve volume The amount of air that can be forced out after tidal volume. Inspiratory reserve volume decreases during exercise. 11 of 23 Inspiratory reserve volume The amount of air that can be forced in after tidal volume. Inspiratory reserve volume decreases during exercise. 12 of 23 Residual volume The amount of air that remains in the lungs after maximal expiration. There is no change in residual volume during exercise. 13 of 23 Vital capacity The largest volume of air that can be forcibly expired after the deepest possible inspiration. 14 of 23 What is the average amount of heart beats per minute for an adult? 72 beats per minute 15 of 23 One heart beat One heart beat is one contraction and relaxtion of the heart. 16 of 23 Parts of the heart Superior vena cava, aorta, pulmonary vein and artery, valves, left + right ventricle, left + right atrium, septum. 17 of 23 Diastole Phase of the heartbeat when the chambers of the heart relax and fill with blood. 18 of 23 Systole Phase of the heartbeat when the chambers of the heart contract and empty the blood. 19 of 23 Vasoconstriction Where the blood vessels constrict / get smaller to reduce the volume of blood. 20 of 23 Vasodilation Where the blood vessles dilate / widens to allow more blood do go through it. 21 of 23 Stroke volume The volume of blood pumped out of the heart by each ventricle during one contraction. 22 of 23 Cardiac output The volume of blood ejected from the heart in one minute. Cardiac Output = SV X HR 23 of 23
