Ms. He's Circulatory system

  1. 1. Circulatory System
  2. 2. BIG IDEACirculatory system supplies entire body withoxygenated blood • Components of Blood • Type of circulation • Blood vessels: Artery, Vein, Capillary • Heart
  3. 3. Circulatory SystemParts of circulatory system:1.Blood2.Blood vessels3.Heart
  4. 4. Blood Components % Type Structure Function makeup No nucleusRed blood Transports Disk-shaped, flexible 45 cells oxygen Contains hemoglobin White Have a nucleus Fights <1blood cells Short life span infectionsPlatelets Made of cell fragments Blood clotting <1 Protein-rich liquid Carries blood Plasma 55 Contains electrolytes cells
  5. 5. Red and White Blood Cells
  6. 6. Overview of Circulation• Pulmonary circulation: blood flow between the heart and lungs• Systemic circulation: blood flow from heart to rest of the body• Cardiac circulation: blood flow within the heart
  7. 7. Pathway of Blood Flowhttp://www.tracleer.com/Content/Images/heart-lung-circulation.jpg
  8. 8. Pathway of Blood Flow: Blood Vessels (capillaries) Lung Vein pulmonary circulation Artery HEART Vein systemic circulation Artery Body (capillaries)
  9. 9. Blood Vessel Function Vessel Function Examples Transports blood AWAY Aorta Artery from the heart Pulmonary artery Transports blood Vena cava Vein TOWARDS the heart Pulmonary vein Capillary beds Exchange substancesCapillary found throughout between blood and body body

  12. 12. 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 & wastehttp://faculty.stcc.edu/AandP/AP/imagesAP2/bloodvessels/endothelia.jpg

  19. 19. 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
  20. 20. Capillaries and Blood Flow • 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 http://antranik.org/wp-content/uploads/2011/12/red-blood-cells-in-a-capillary.jpg
  21. 21. Blood Flow in Blood Vessels Structure that Vessel Explanation aids blood flow Walls expand & contract helping to Artery Elastic walls pump blood One-way Valves act as doors preventing Vein valves backward blood flow Small Blood cells travel in single file pullingCapillary circumference each other along like a chain
