12. Homeostasis Internal environment of the body kept relatively stable
11/12/2018
Homeostasis
Internal environment of the body kept relatively stable
state without change
Actually to maintain this our bodies are constantly changing
Hypothalamus - thermostat

13. 11/12/2018
Homeostasis
Hot
Cold

14. Negative Feedback Loop
11/12/2018
Negative Feedback Loop
Used to maintain a stable internal environment
Triggered by changes in the norm
usually temperature, pH, or hormonal
From:

18. Positive feedback Birth Bleeding
11/12/2018
Positive feedback
Birth
Oxytocin (causes contractions) is released due to pressure on the cervix
More oxytocin is released due to increased pressure on the cervix
Ends when the fetus is expelled
Bleeding
clotting yields more clotting yielding more clotting - eventually stopped by stopped blood flow
