Transcript

  • 1. 2.01 Remember the structuresof the circulatory system
  • 2. Essential questions What are the structures of blood? What are the structures of the circulatory system? 2.01 Remember the structures of the circulatory system 2
  • 3. Structures of the circulatory system  Blood  Heart  Arteries  Veins  Capillaries 2.01 Remember the structures of the circulatory system 3
  • 4. Blood HematologyHemat- = blood-ology = the study of The average adult has 8 – 10 pints. 2.01 Remember the structures of the circulatory system 4
  • 5. BloodOne single drop of blood contains:  5 million RBCs  250,000-500,000 platelets  7,500 WBCsMake new blood cells 2 million per second! 2.01 Remember the structures of the circulatory system 5
  • 6. Structures of the blood  Plasma  Erythrocytes  Leukocytes  Thrombocytes 2.01 Remember the structures of the circulatory system 6
  • 7. Plasma Plasma Cellular elements 2.01 Remember the structures of the circulatory system 7
  • 8. Plasma proteins Plasma Cellular elements 2.01 Remember the structures of the circulatory system 8
  • 9. Erythrocytes(erythro=red + cytes=cells) Live 120 days Biconcave disk Hemoglobin Transportation  Oxygen  Carbon dioxide 2.01 Remember the structures of the circulatory system 9
  • 10. Leukocytesleuko=white + cytes=cells 2.01 Remember the structures of the circulatory system 10
  • 11. Leukocytes Agranulocytes  Lymphocytes  Monocytes 2.01 Remember the structures of the circulatory system 11
  • 12. Leukocytes Granulocytes  Neutrophils  Eosinophils  Basophils 2.01 Remember the structures of the circulatory system 12
  • 13. Thrombocytes/Platelets  Smallest of solid components of blood  Synthesized in red marrow  Not cells, composed of fragments of megakaryocytes  Necessary for the initiation of the blood clotting process 2.01 Remember the structures of the circulatory system 13
  • 14. 2.01 Remember the structures of the circulatory system 14
  • 15. Blood types  A  B  AB  O 2.01 Remember the structures of the circulatory system 15
  • 16.  In 1901, the Austrian immunologist Karl Landsteiner discovered that blood may be grouped into four main types. Based on the reaction that resulted when blood from different individuals were mixed. 2.01 Remember the structures of the circulatory system 16
  • 17. Blood types  Someone with type A antigen has B antibodies  Someone with type B antigen has A antibodies  Someone with type AB antigen has no antibodies  Someone with type O antigen has A and B antibodies 2.01 Remember the structures of the circulatory system 17
  • 18. Rh factor Rhesus (Rh) factor is an  Although Rh factor doesnt inherited trait that refers to a affect the patient’s health, it specific protein found on the can affect pregnancy. surface of red blood cells (antigen). Blood used in transfusions must match donors for Rh status as well as for ABO blood type. 2.01 Remember the structures of the circulatory system 18
  • 19. Rh factor In 1940, the Rh factor was discovered as a result of studying Rhesus monkeys. When blood from monkeys was injected into rabbits and guinea pigs, it clotted. 2.01 Remember the structures of the circulatory system 19
  • 20. Rh factor If the blood has the protein, the patient is Rh positive. If the blood lacks the protein, the patient is Rh negative. 2.01 Remember the structures of the circulatory system 20
  • 21. Structures of the circulatory system  Heart 2.01 Remember the structures of the circulatory system 21
  • 22. Heart The heart is a double pump. 2.01 Remember the structures of the circulatory system 22
  • 23. Heart Aorta Superior vena cava Pulmonary arteryAortic semilunar valve Pulmonary vein Right atrium Left atrium Tricuspid valve Bicuspid (mitral) valve Inferior vena cava Pulmonary semilunar valve Right ventricle Left ventricle Septum Apex 2.01 Remember the structures of the circulatory system 23
  • 24. Layers of the heart Left atrium Right atrium Pericardium Myocardium Endocardium Right ventricle Left ventricle 2.01 Remember the structures of the circulatory system 24
  • 25. Conduction system of heart beats Refer to your textbook to identify the structures of the heart’s conduction system in the correct sequence for the heart to beat. 2.01 Remember the structures of the circulatory system 25
  • 26. Structures of the circulatory system  ARTERIES 2.01 Remember the structures of the circulatory system 26
  • 27. Vessels of the circulatory system ARTERIES  Elastic, muscular and thick-walled  Three tissue layers  Tunica adventitia  Tunica media  Tunica intima  Transport blood AWAY from the heart under very high pressure Arteries > arterioles > capillaries 2.01 Remember the structures of the circulatory system 27
  • 28. Vessels of thecirculatory system Arterial blood Oxygen rich Bright red, spurts 2.01 Remember the structures of the circulatory system 28
  • 29. Structures of the circulatory system  VEINS 2.01 Remember the structures of the circulatory system 29
  • 30. Vessels of the circulatory system VEINS  Carry deoxygenated blood from capillaries to the heart  Veins contain a muscular layer, but less elastic and muscular than arteries  Thin walled veins collapse easily when not filled with blood  Veins have one way valves that prevent the backflow of blood  Veins > Venules > Capillaries 2.01 Remember the structures of the circulatory system 30
  • 31. Vessels of thecirculatory systemVenous blood Oxygen poor Dark crimson, oozes 2.01 Remember the structures of the circulatory system 31
  • 32. Flow of BloodArteries > arterioles > capillaries > Venules > Veins 2.01 Remember the structures of the circulatory system 32
  • 33. Vessels of the circulatory system 2.01 Remember the structures of the circulatory system 33
  • 34. Structures of the circulatory system  Capillaries  The smallest blood vessels  Connect arterioles to venules 2.01 Remember the structures of the circulatory system 34
  • 35. Structures of the circulatory system Trace the flow of blood through the body 2.01 Remember the structures of the circulatory system 35
  • 36. Flow of blood through the body Right side Left Side Superior vena cava Pulmonary vein Inferior vena cava Left atrium Right atrium Bicuspid valve Tricuspid valve Left ventricle Right Ventricle Aortic valve Pulmonary valve Aorta Pulmonary artery Body Lungs CO2 and O2 exchange 2.01 Remember the structures of the circulatory system 36
  • 37. Pulse sites Alternating expansion and contraction of an artery as blood flows through it. 2.01 Remember the structures of the circulatory system 37
  • 38. Common pulse sites 2.01 Remember the structures of the circulatory system 38
