  1. Exercise and Health The Circulatory System

  2. The Circulatory System • Blood circulates to every cell in the body. • The following diagram shows the main blood vessels and explains how blood circulates to all parts of the body.

  3. head and arms

  4. head and arms pulmonary artery

  5. head and arms pulmonary artery pulmonary vein

  6. head and arms pulmonary artery pulmonary vein lungs

  7. head and arms pulmonary artery pulmonary vein lungs vena cave

  8. head and arms pulmonary artery pulmonary vein lungs aorta vena cave

  9. head and arms pulmonary artery pulmonary vein lungs aorta vena cave liver

  10. head and arms pulmonary artery pulmonary vein lungs aorta vena cave hepatic artery hepatic vein liver

  11. head and arms pulmonary artery pulmonary vein lungs aorta vena cave hepatic artery hepatic vein liver digestive system

  12. head and arms pulmonary artery pulmonary vein lungs aorta vena cave hepatic artery hepatic vein liver hepatic portal vein digestive system

  13. head and arms pulmonary artery pulmonary vein lungs aorta vena cave hepatic artery hepatic vein liver hepatic portal vein digestive system kidneys

  14. head and arms pulmonary artery pulmonary vein lungs aorta vena cave hepatic artery hepatic vein liver hepatic portal vein digestive system renal vein renal artery kidneys

  15. head and arms pulmonary artery pulmonary vein lungs aorta vena cave hepatic artery hepatic vein liver hepatic portal vein digestive system renal vein renal artery kidneys legs

  16. Blood

  17. Red cells

  18. Red cells • Do not have a nucleus • Biconcave discs • Contain the chemical haemoglobin. • Haemoglobin carries oxygen around the body. • At the centre of the haemoglobin molecule is an iron atom.

  19. air sac in the lung

  20. air sac in the lung oxygen

  21. air sac in the lung oxygen 1 as blood flows through the lungs the haemoglobin in the red cells picks up oxygen

  22. air sac in the lung 2 Haemoglobin and oxygen join to make oxyhaemoglobin oxygen 1 as blood flows through the lungs the haemoglobin in the red cells picks up oxygen

  23. air sac in the lung 2 Haemoglobin and oxygen join to make oxyhaemoglobin oxygen 3 when the blood flows past cells with very little oxygen in them the oxyhaemoglobin breaks down 1 as blood flows through the lungs the haemoglobin in the red cells picks up oxygen

  24. air sac in the lung 2 Haemoglobin and oxygen join to make oxyhaemoglobin oxygen 3 when the blood flows past cells with very little oxygen in them the oxyhaemoglobin breaks down 1 as blood flows through the lungs the haemoglobin in the red cells picks up oxygen oxygen diffuses into the cells of the body oxygen is used for respiration

  25. air sac in the lung 2 Haemoglobin and oxygen join to make oxyhaemoglobin oxygen 3 when the blood flows past cells with very little oxygen in them the oxyhaemoglobin breaks down 1 as blood flows through the lungs the haemoglobin in the red cells picks up oxygen 4 the haemoglobin in the red cells goes back to the lungs to pick up more oxygen oxygen diffuses into the cells of the body oxygen is used for respiration

  26. Functions of the blood • Oxygen is carried in the red cells • Carbon dioxide is carried in the plasma

  27. Functions of the blood • digested foods are carried in the plasma

  28. Functions of the blood • Urea (waste substance)is carried in the plasma from the liver to the kidneys

  29. Functions of the blood • Hormones are carried in the plasma

  30. Functions of the blood • Heat is carried in the blood

  31. BIOLOGY TEXT • Read p26-27 and answer question 1 off p27
