- NEGATIVE FEEDBACK:
- You are sweating because your body is trying cool you off, making so you return to your set point, or ideal body temperature. This is also why you're turning red. This is known as Negative Feedback.
- In this particular cycle, the receptors affected are temperature-sensitive cells in your skin and brain that afferents the brain. Then the control center, the thermoregulatory center in your brain, efferents the sweat glands. The sweat glands are the effectors.
- POSITIVE FEEDBACK:
- While Megan was running on the tradmill, she was feeling very hot. Her friend, Eric, notices that her skin was appearing as a light shade of red, and she was very sweaty.
- Megan decided to take a brake because she wasn't quite sure she was turning red and so sweaty. This is when Eric began to tell her that her body was demonstrating negative feedback, a form of homeostasis.
- In this particular cycle, the receptors affected are the break/tear that occurs in the blood vessel wall that then afferents the brain. The control center then efferents platelets to fix the tear. The platelets that adhere to the site and release chemicals are the effectors. The cycle ends whent he plug is formed.
- Positive feedback is when the body amplifies. By scraping your knee, Zack, your body is going above and beyond to protect your wound by scabbing up and making a scar.
- After Megan realized what her body was a good thing, she returned back to the treadmill and resumed her workout.
- Zack and Sara meet thir 2 friends at the park and begin playing a pick-up game of 2 on 2 basketball. While playing, Zack falls and scrapes his knee on the pavement.
- Once everybody found out he was okay, Sara began to tell the group about how Zack is demonstrating positive feedback. She goes on to tell the group what positive feedback is. One of her friends also chimes in on the discussion.
- After Zack realized his scraped knee was going to okay, the group of friends finish their game of 2 on 2.
