Presentation Transcript

  1. Circulatory and Respiratory systems

  2. Shade in low oxygen blood as blue and highly oxygenated blood as red

  3. from head to lungs from trunk

  4. to head/arms from lungs from lungs to trunk

  5. a • Artery • Carries blood away from heart

  6. B • Right atria • Receives blood from body

  7. C • Valve • Opens and closes to control blood flow

  8. D • Right ventricle • Pushes blood to lungs

  9. E • Left ventricle • Pushes blood to body

  10. F • Left atria • receives blood from lungs

  11. Respiratory system • 1= nose • 2=mouth • 3=larynx • 4= lung • 5= bronchi • 6= diaphragm • 7= pharynx • 8= trachea

  12. 9= bronchi • 10= bronchiole • 11= alveoli • 1000’s of thin walled sacs for diffusion • Alveoli is 1 cell thick and capillary is 1 cell thick

  13. Bronchi

  14. Bronchiole • branches

  15. Alveoli • 1000’s of thin walled sacs for O2/CO2 diffusion • 1 cell thick, capillary is 1 cell thick

  16. What about a shark or fish?

  17. Asthma • Bronchiole tubes are clamped down by the muscles around the tubes • Keeps oxygen from alveoli

  18. Stop for day 1

  19. Respiration reaction • Sugar plus • Oxygen plus • Water • Yields • 38 ATP plus • Carbon dioxide plus • water

  20. If no oxygen • Glucose yields • Lactic acid (ouch) and 2 ATP • Add oxygen (b/c you are laying on ground gasping for air) • Returns to respiration reaction

  21. Heart attack • Arteries that feed the heart muscle do not work because of a clot, or plaque (fat build up)

  22. Symptoms • Elephant on the chest, pain in arms b/c • low oxygen stimulates the nervous system to let you know there is a problem

  23. Symptoms • Shortness of breath b/c • Poor pumping of heart, so fluid is building up in lungs

  24. Symptoms • Sweating, nausea, light headed, because of • Low oxygen to the brain, brain shuts you down

  25. Cross sections

  26. Blood components • RBC: red because of hemoglobin • Carries oxygen and carbon dioxide • Look like jelly donuts

  27. White blood cells • From immune system

  28. Platelets • For clotting, stops you from bleeding

  29. Plasma- • Liquid • Carries proteins, hormones, enzymes, food, water and wastes
