Presentation Transcript

  1. Respiratory and Circulatory Systems

  2. Other Animal’s Respiration: • Sponge, hydra, planaria – diffusion from water • Earthworm – skin • Insect – spiracles and trachea lead to air sacs • Fish – gills

  3. Other Animal’s Circulation: • Sponge, hydra, planaria – diffusion • Earthworm – aortic arches • Insect – dorsal heart • Fish – 2-chambered heart • Amphibian – 3 chambered heart • Reptile and bird – 3+ chambered heart

  4. These systems are interrelated in humans

  5. Anatomy of Our Respiratory System Site of gas exchange

  6. What happens when we breathe?

  7. Problems with Respiration • Infection – colds, flu, pneumonia • Bronchitis • Asthma • cancer

  8. Our blood actually takes two paths during circulation

  9. Human Heart circulation • Pathway: • Enters heart from superior and inferior vena cavae • Right atrium • Right ventricle • Pulmonary arteries • To the Lungs • 4. Pulmonary veins • 5. Left atrium • 6. Left Ventricle • 7. Aorta • To the rest of the body

  10. These are the arteries involved in heart attacks

  11. Components of Blood

  12. Blood Vessels

  13. Problems of the Circulatory System • Heart attack • Angina • High blood pressure (hypertension) • Palpitations

  14. The End
