1 Cardiovascular System Revision Worksheets - 1-1

2 The Heart Label this heart using the words provided 1. inferior vena cava 14. right ventricle 8. bicuspid valve (mitral) 5. tricuspid valve 7. septum 11. right atrium 6. superior vena cava 4. endocardium 15. left atrium 2. aorta 10. myocardium 13. (left) pulmonary artery 3. one of 4 pulmonary veins 9. left ventricle 12. pericardium - 2-2

3 Bloodflow through Heart Exercise - Put these labels into the correct order Oxygenated blood leaves heart via aorta to travel around body Deoxygenated blood enters right atrium by way of vena cava Deoxygenated blood goes from right atrium to right ventricle Deoxygenated blood goes to lungs via pulmonary artery Oxygenated blood from lungs goes by way of pulmonary vein to left atrium Oxygenated blood goes from left atrium to left ventricle - 3-3

4 DISEASES AND DISORDERS OF THE CARDIOVASCULAR SYSTEM Match the disorders listed below to the correct descriptions. Rheumatic Fever, Thrombosis, Arteriosclerosis, Varicose Veins, Septicaemia, Simple Anaemia, Heart Failure, Haemophilia, Atherosclerosis, Hypertension, Leukaemia, Angina Pectoris, High Cholesterol, Phlebitis Chest Pain caused by reduced oxygen supply to the heart. Toxins in the blood Deficiency in the clotting of blood Clot of blood within the heart or blood vessels High blood pressure Malignant disease of the white blood cells which continuously increase Heart not capable of supplying the oxygen demands of the body 8 Excessive amount of fatlike material present in the blood 9 Hardening of the arteries Inflammation of the wall of a vein, which is most commonly seen in the legs as a complication of varicose veins Fatty substances deposited on walls of arteries Inflammation of the heart that damages valves due to bacteria Stretched veins causing impaired valves Deficiency in Iron - 4-4

5 CARDIOVASCULAR SYSTEM - Bloodflow Put these in order in which blood flows through them from the heart: LEG 1. Anterior tibial 2. Femoral 3. Iliac 4. Plantar arches 5. Posterior tibial 6.

6 CARDIOVASCULAR SYSTEM WORKSHEET 1. Name a leg vein that does not have a correspondingly named artery 2. Name 2 veins in the neck that do not have correspondingly named arteries 3. Name 2 veins in the arm that do not have correspondingly named arteries 4. Name the major artery in the neck 5. Complete the following table: thickness of walls pressure of blood valves? Blood TO or AWAY from heart How blood is moved along vessels Deep seated or close to surface? Arteries Veins - 6-6

7 CARDIOVASCULAR SYSTEM Self Assessment Questions 1. State which chamber of the heart: a) Receives blood from the lungs b) Receives blood from the systemic circulation c) Pumps blood to the lungs d) Pumps blood to the systemic circulation 2. Choose the correct blood vessels for each statement: - a) Carry blood to the heart b) Allow transfer of nutrients and waste products between blood and tissues c) Carry blood away from the heart Choose from:- i) Arteries ii) Veins iii) Capillaries 3. What are the names of the two main veins, which enter the right atrium of the heart? 4. Circle the correct figure. The heart beats at an average rate of (50/75/100/120) beats per minutes. 5. Where does the heart muscle get its own blood supply from? 6. Where is the tricuspid valve found? 7. Blood returns from the lungs to the heart via the:- a) Pulmonary artery b) Pulmonary vein c) Aorta d) Inferior vena cava 8. Which of the following are not arteries:- a) Femoral b) Popliteal c) Superior vena cava d) Coronary e) Jugular f) Mitral 9. Give three major factors influencing blood pressure. 10. Blood pressure can be expressed as two numbers e.g. 120/80 a) What does 120 represent? b) What does 80 represent? - 7-7
