EXTENSION QUESTIONS  What is the role of systemic circulation?  Arteries get become smaller until they become capillaries. What are the blood vessels called that are found between these two stages.  What is special about capillary walls & why are they like this?  Why do veins have valves in them that open & shut?  The heart has 4 chambers. What are the upper chambers called & what do they do, & what are the lower chambers called & what is their job?  What component of blood gives it its colour?  What is contained in plasma?  What equation would we use to work out cardiac output?  During exercise by how much could blood flow & oxygen being used by the muscles increase by? ANSWERS

EXAM QUESTIONS 1. Which organ pumps blood around the body?(1 mark) 2. Give 2 functions of the blood.(2 marks) 3. Which part of the blood carries oxygen?(1 mark) 4. What are veins?(1 mark) 5. Give 2 waste products carried in the veins.(2 marks) 6. Give 3 features of an efficient heart.(3 marks) 7. What is the pulse?(1 mark) 8. Give 3 ways in which pulse rate can give an indication of physical fitness. (3 marks) 9. How does taking part in sport & physical activity affect circulation. (4 marks ) 10. What is the heart made of?(1 mark) 11. Which main blood vessels carry blood away from the heart?(1 mark) 12. What is cardiac output?(2 marks) 13. What is stroke volume & how does it affect performance?(5 marks) 14. Give another name for cardio-vascular fitness.(1 mark) ANSWERS

EXTENSION ANSWERS The systemic circulation delivers blood around the body. Aterioles Capillary walls are only 1 cell thick to allow nutrients & waste products to pass through the walls into & from the blood stream. Veins have valves to prevent blood flowing backwards. The upper chambers are called ‘atria’ or an ‘atrium’ & their role is to fill with blood coming into the heart. The lower chambers are known as ‘ventricles’ their role is to contract so that blood is forced out to the lungs & the body. Red blood cells give blood its colour. Plasma contains dissolved substances such as salts, calcium, glucose, hormones & waste products like carbon dioxide. Heart Rate x Stroke Volume = Cardiac Output During exercise blood flow could increase 30 times while oxygen delivery up to 3 times.

EXAM ANSWERS 1. The heart. 2. Transport, protection, temperature regulation & maintain the body’s equilibrium. 3. Haemoglobin. 4. Blood vessels. 5. Carbon dioxide, water & lactic acid. 6. Large stroke volume, low resting pulse, high cardiac output. 7. The force of blood against the artery walls. 8. Low resting pulse, high maximum heart rate, quick recovery. 9. Increased cappillarisation, increased stroke volume, increased cardiac output, increased oxygen transport. 10. Cardiac muscle. 11. Arteries. 12. The volume of blood pumped out of the heart in 1 minute. 13. The amount of blood that leaves the heart per beat. If it is low fatigue will set in quickly as will maximum heart rate as not enough blood will deliver enough oxygen for the demands of the working muscles.The bigger it is the longer you can work before fatigue sets in as oxygen requirements are being met. 14. Stamina/endurance/aerobic fitness.
