Body System Review 1

1. 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?
2. The body system that works to transport molecules (good and bad) around the body.
4. This type of cell transport is responsible for gas change.
6. the anatomical term for "windpipe" allows gas to travel from nose/mouth to the lungs.
8. this organ is not made of muscle, but is made of millions of branches and air sacs that fill with gas during respiration.
11. this type of neuron functions to detect changes inside or outside the body and send it to the brain
13. A thin layer of muscle beneath the lungs that contracts and relaxes to allow the lungs to inflate and deflate.
15. this type of feedback loop works to continue a change in the body for a large outcome.
16. the body's ability to maintain a stable internal environment.
17. describes the structure, composition or location of body parts.
19. this type of feedback loop works to reverse a change in homeostasis.

1. Very thick, muscular blood vessels that pump blood away from the heart.
3. The body system that brings in oxygen gas and expels carbon dioxide.
5. extremely thin blood vessels that are the site of gas exchange.
7. the small air sacs within the lung that are the site of gas exchange.
9. The body system that detects and responds to stimulus inside and outside the body.
10. describes the function or role a body part plays.
12. What occurs when the body ha prolonged periods where homeostasis is not maintained?
14. this type of neuron functions to carry messages from the brain and respond to stimulus.
18. this gas diffuses from the lung into the blood.
