1. Assessment StatementsObj. 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

2. http://youtu.be/ILxjxfB4zNk 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. Call for help. Push hard and fast to the beat of Stayin’ Alive. Don’t stop until help arrives.

3. Data practice: CPR survival rates. Get started early to save a life! These data compare compression-only CPR with conventional CPR: neurologically favorable 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 hands- only CPR and conventional CPR in cases of non- cardiac origin after 7-8 minutes. 3.Compare survival rates between cases of cardiac and non-cardiac origin. Suggest a reason for the differences. http://www.bmj.com/content/342/bmj.c7106.full Data from:

14. Your Task – To create a life size model of the body over the course of the Human Physiology Unit Circulatory Section– Materials : Large Poster Paper Construction Paper Scissors Tape Markers Steps – 1.Cut out and label a model heart and put it on the body in the correct positioning. 2.Cut you must include one MAJOR artery and vein in your person, and these should connect with the heart appropriately. 3.You should also include the capillaries that interact with the digestive system (and allow for the absorption and assimilation of nutrients from food. 4.Place all the required parts of your person in the appropriate position.

15. Fetal Circulation Patterns Compare the blood flow in an adult heart (right) with that of a fetal heart (left), based on the provided images. Where does the blood get its oxygen? What path does it take through the heart? Fetal Heart Adult Heart
