  1. Cardiovascular & CirculatorySystems

  2. Cardiovascular & Circulatory System Function: The Body’s Transport System 1. Heart 2. Blood Vessels 3. Blood

  3. Structures - Heart 1. Shape - Strawberry 2. Size - Fist Weight - 1 pound 3. 4. Location – Center of chest

  4. THE HEART

  5. Heart - Structures 1. Septum – Divides the Heart into Right and Left 2. Chambers - - Atrium – Top (smaller) - Ventricle – Bottom (bigger) 3. Valves – Keep blood flowing in one direction Note: It Is A Hollow Organ

  6. Heart Animation • http://www.youtube.com/watch?v=H04d3rJCLCE • http://www.youtube.com/watch?v=rBQOLiFto6Q

  7. 1. Arteries – (RED) Carries Blood Away from the Heart Blood Vessels 2. Veins – (BLUE) Carry Blood Back to the Heart 3. Capillaries – Where exchange of nutrients takes place (O2, Waste, Etc…)

  8. Blood Vessels • http://www.youtube.com/watch?v=CjNKbL_-cwA • Circulation- http://www.youtube.com/watch?v=PgI80Ue-AMo&feature=related • Capillaries- http://www.youtube.com/watch?v=Q530H1WxtOw

  9. Blood Pressure Definition: The Force of the Blood against the Walls of the Arteries Systole: Top Number of Blood Pressure (ventricles contracting) Diastole: Bottom Number of Blood Pressure(ventricles filled w/ blood)

  10. Blood - Function 1. Carries food and oxygen to all cells 2. Rids the body of Waste

  11. Blood -Components 1. Red Blood Cells - Erythrocytes 2. White Blood Cells - Leukocytes 3. Platelets - Thrombocytes 4. Plasma

  12. Red Blood Cells 1. Made in the Marrow of Bones 2. Carry Oxygen 3. Hemoglobin - The Protein that attracts O2 to the RBC - Prone to Defect/illnesses

  13. Blood Components • http://www.youtube.com/watch?v=R-sKZWqsUpw • http://www.youtube.com/watch?v=CRh_dAzXuoU

  14. White Blood Cells 1. Made in the Marrow of Bones 2. Defend the Body against Disease

  15. Plasma 1. The Liquid part of Blood (55% of blood) 2. Mostly Water

  16. Blood Components

  17. Platelets 1. Aid in Blood Clotting 2. How Does Blood Clot? - Cut occurs. Platelets Activated. - Platelets RUSH to the wound - Fibrin is released (Spider Web) - Web is formed over Wound Trapped Cells Harden and form a Scab -

  18. PLATELETS = SPIDERMAN

  19. Cut occurs…. Platelets Actived! PLATELETS- STEP 1

  20. Platelets RUSH to the wound! PLATELETS – STEP 2

  21. Fibrin is released (Spidey Web) PLATELETS- STEP 3

  22. Web is formed over Wound. PLATELETS – STEP 4

  23. -Trapped Cells Harden and form a Scab PLATELETS – STEP 5 SPIDEY SAVES THE DAY 

  24. Platelets • http://www.youtube.com/watch?v=--bZUeb83uU&feature=related • http://www.youtube.com/watch?v=vEmsaXA-go0 • http://www.youtube.com/watch?v=JvOH5skxqoA • http://www.youtube.com/watch?v=M_YpLaWdBpk

  25. Blood Types A, B, AB, O Donor: Person who gives Blood Recipient: Person who receives Blood Clumping: Occurs when the blood types do not mix

  26. Blood Types A, B, AB, O Recipient D o n o r *O = Universal Donor *AB =Universal Recipient

  27. BLOOD TYPES http://www.youtube.com/watch?v=MZ6_hSvjV_E

  28. Really hard Logic/Blood Type Puzzle? Use the following information to predict each person's blood type. Bill can give blood to joe mike and sue Don can give blood to bob but not bill Bob can give blood to Mike but not Joe Tom can give blood to kelly, Sue, Don, and mike Kelly can give blood to sue and bob but not to tom sue cannot give blood to kelly joe can give blood to mike but not bob or sue mike can GET blood from sue and bill Joe does not have an A antigen Bill________ Bob_______ Don_______ Joe_______ Kelly______ Mike_______ Sue_______ Tom_______ Answer in terms of blood type (A, B, AB, or O) By the way, this may help: a can be given to a or ab b can be given to b or ab ab can be given to ab o can be given to anyone http://answers.yahoo.com/question/index?qid=20080526202704AAo5bWa BLOOD TYPE CHALLENGE

  29. Heart Attack http://www.heartinfo.org/ms/animations/13/main.html http://www.youtube.com/watch?v=DGxS44-rcps&feature=related http://www.youtube.com/watch?v=0bLQjMaLilM&feature=related

  31. PROBLEMS 1. Congenital Heart Disease:A number of heart defects that you are born with.

  32. Problems 2. Heart Murmur: Valves do not close completely http://www.youtube.com/watch?v=3NapobA3QbI&feature=PlayList&p=157240A8B6B0EC19&index=0&playnext=1

  33. HEART VALVES

  34. PROBLEMS • 3. VERICOSE VEINS - Swollen and enlarged veins caused by weak valves • http://www.youtube.com/watch?v=LCXg2WBPtOQ&feature=related

  35. VERICOSE VEINS

  36. Problems 4. Anemia: Low Levels of Hemoglobin http://www.youtube.com/watch?v=_ZV5140OykE Sickle Cell Anemia: 5. Inherited condition that causes Blood Clotting http://en.wikipedia.org/wiki/Sickle_cell http://www.youtube.com/watch?v=BkC5Hf-AKwo&feature=related

  37. PROBLEMS • 6. HEMOPHILIA - Inherited disease. Blood does not clot

  38. PROBLEMS • 7. LEUKEMIA – Cancer of the bone marrow. Effects white blood cells. • http://www.youtube.com/watch?v=SGj2vsdr-ks&feature=related
