Transport System (Core) Stephen Taylor i-Biology.net Assessment Statements Obj. 6.2.1 Draw and label a diagram of the heart showing the four chambers, associated blood vessels, valves and the route of blood through the heart. 1 6.2.2 State that the coronary arteries supply heart muscle with oxygen and nutrients. 1 6.2.3 Explain the action of the heart in terms of collection of blood, pumping blood and opening and closing of valves. 3 6.2.4 Outline control of the heartbeat in terms of myogenic muscle contraction, the role of the pacemaker, nerves, the medulla of the brain and epinephrine (adrenaline). 2 6.2.5 Explain the relationship between the structure and function of arteries, capillaries and veins. 3 6.2.6 State that blood is composed of plasma, erythrocytes, leucocytes (phagocytes and lymphocytes) and platelets. 1 6.2.7 State that the following are transported by the blood: nutrients, oxygen, carbon dioxide, hormones, antibodies, urea, heat. 1 Flip it: • Allott & Mindorff: p219-225, Allott p48 • i-Biology: http://goo.gl/KetyW • Watch Hank: http://youtu.be/9fxm85Fy4sQ • Complete the Quia Quiz before class. Command terms: http://i-biology.net/ibdpbio/command-terms/ Assessment statements from: Online IB Biology Subject Guide Hands-only CPR. Your blood has oxygen in it – but it is not getting to the brain and other organs. Hands-only CPR keeps the blood flowing until help arrives with the Automatic External Difibrilator (AED). The electrical signal is needed to re-start the heart, and we’ll learn why this is in a little while. http://youtu.be/ILxjxfB4zNk Call for help. Push hard and fast to the beat of Stayin’ Alive. Don’t stop until help arrives. Learn more here: http://www.bhf.org.uk/heart-health/life-saving-skills/hands-only-cpr.aspx Data practice: CPR survival rates. Get started early to save a life! These data compare compression-only CPR with conventional CPR: neurologically favourable one-month survival. Population: bystander-assisted patients, transferred to hospital by ambulance. Japan. 2005 – 2007. Compression-only n=20,707 Conventional CPR n= 19,328 1. Compare survival rates of compression-only CPR with conventional CPR in all cases (top graph). 1. Describe the effect of increasing time to start CPR on survival of patients in cases of cardiac origin. 2. Calculate the difference in survival between handsonly CPR and conventional CPR in cases of noncardiac origin after 7-8 minutes. 3. Compare survival rates between cases of cardiac and non-cardiac origin. Suggest a reason for the differences.
