  1. Circulatory SystemRefer to booklet pages 29 - 32 Circulation Blood Vessels Heart Blood Diseases

  2. Overview of CirculationQuestion #1 • Cardiac circulation: blood flow within the heart • Pulmonary circulation: blood flow between the heart and lungs • Systemic circulation: blood flow from heart to rest of the body

  3. Pathway of Blood Flow http://www.tracleer.com/Content/Images/heart-lung-circulation.jpg

  4. Pathway of Blood FlowQuestion #3 Heart Vein Artery Arteriole Venule Capillary

  5. Blood Vessel FunctionQuestion #4

  6. Pathway of Blood Flow Vein Artery Artery Vein http://www.tracleer.com/Content/Images/heart-lung-circulation.jpg

  7. Pathway of Blood Flow http://media.web.britannica.com/eb-media/06/92806-034-95B4D32F.jpg

  8. Capillaries • Walls made up of one thin layer of cells which allow for rapid diffusion of materials from blood to surrounding tissue • Materials exchanged: • Gases: oxygen, carbon dioxide • Nutrients & waste http://faculty.stcc.edu/AandP/AP/imagesAP2/bloodvessels/endothelia.jpg

  9. Gas Exchange in Capillaries of Body https://www.cdli.ca/courses/biol2201/unit03_org02_ilo02/cappillarya.JPG

  10. Gas Exchange in Capillaries of Lung http://media-2.web.britannica.com/eb-media/37/92937-034-1E4EA526.jpg

  12. Gas Exchange in Capillaries

  13. Blood Vessel Structure

  14. Valves Question #5 Valves act as doors preventing backward blood flow

  15. Veins and Blood Flow • Valves open when muscles contract, allowing blood to return to the heart • Valves close when muscles relax so that blood cannot flow backwards. http://www.thecosmeticveincenter.com/images/veins.png

  16. Varicose Veins: Deformed Valves http://www.varicoseveinguide.com/images/varicoseveins2.jpg http://www.sciencephoto.com/image/263331/530wm/M2900102-Varicose_veins_affecting_the_leg_of_an_elderly_man-SPL.jpg

  17. Small diameter in capillaries are only wide enough for red blood cells to travel in a single file Red blood cells pull each other along like a chain Capillaries and Blood Flow http://antranik.org/wp-content/uploads/2011/12/red-blood-cells-in-a-capillary.jpg

  18. Arterial wallsQuestion #6 • Elastic walls in arteries keep blood flowing

  19. The human heart

  20. Cardiac Circulation • 4 chambers • 4 valves • 2 arteries • 2 veins • Deoxygenated blood • Oxygenated blood http://www.sdm.scot.nhs.uk/images/pfo.jpg
