Across
  1. 1. extremely thin blood vessels that are the site of gas exchange.
  2. 6. this organ is not made of muscle, but is made of millions of branches and air sacs that fill with gas during respiration.
  3. 7. The body system that detects and responds to stimulus inside and outside the body.
  4. 8. this type of feedback loop works to reverse a change in homeostasis.
  5. 10. A thin layer of muscle beneath the lungs that contracts and relaxes to allow the lungs to inflate and deflate.
  6. 12. What occurs when the body ha prolonged periods where homeostasis is not maintained?
  7. 13. The reason for respiration is the cells continue to require oxygen and produce CO2 during cellular respiration. What important molecule is produced during cellular respiration?
  8. 15. The body system that works to transport molecules (good and bad) around the body.
  9. 16. the body's ability to maintain a stable internal environment.
  10. 17. the small air sacs within the lung that are the site of gas exchange.
  11. 20. this type of neuron functions to detect changes inside or outside the body and send it to the brain
Down
  1. 2. Very thick, muscular blood vessels that pump blood away from the heart.
  2. 3. This type of cell transport is responsible for gas change.
  3. 4. this gas diffuses from the lung into the blood.
  4. 5. The body system that brings in oxygen gas and expels carbon dioxide.
  5. 9. the anatomical term for "windpipe" allows gas to travel from nose/mouth to the lungs.
  6. 11. this type of neuron functions to carry messages from the brain and respond to stimulus.
  7. 14. describes the function or role a body part plays.
  8. 18. describes the structure, composition or location of body parts.
  9. 19. this type of feedback loop works to continue a change in the body for a large outcome.
