Diagrams: [10 marks]
1) On the diagram below, label the following terms: aorta, pulmonary veins, left ventricle,
atrioventricular valve. [4]
2) Use a dotted arrow to indicate the flow of deoxygenated blood returning to the heart, and a
solid arrow to indicate the flow of oxygenated blood being pumped to the rest of the body, on
the diagram above. [2]
3) Label the indicated structures on the diagram below: [4]
Short Answer [23 marks]
1) In one or two sentences, describe the necessity or purpose of the circulatory system. [2]
2) Describe one example of homeostasis in the circulatory system. [3]
3) Use the following terms to explain how a coordinated heart beat occurs. [5]
Right & left atria, right and left ventricles, sinoatrial (SA) node, atrioventricular (AV) node,
Purkinje fibres
4) Think: Which area of the graph represents the blood in a capillary. Explain your answer. [2]
5) Smoking is very harmful on the respiratory system.
a) Describe your body's response to foreign particles in the lungs. [2]
b) Smoking can also lead to lung cancer. How does the cancer kill? [2]
5) You decide to race your friend for a 3 km run. Halfway there, you notice you are breathing
much faster than when you began. Explain why this happened. (Hint: think homeostasis) [3]
