This week we built the four-part negative feedback loop: stimulus, receptor, control center, effector. We saw how the body keeps variables like body temperature, blood glucose, and pH near a set point.
Pick one variable in your own life that you actively regulate, but that is NOT a body variable. Examples: the temperature of your bedroom, your bank account balance, your daily caffeine intake, the brightness of your phone screen.
In your initial post (200-300 words):
- Name the variable and its set point (your target).
- Identify each of the four feedback components in YOUR system (what is the receptor? control center? effector? response?).
- Describe a time the system worked and a time it failed.
- Then tie it to the body: what physiological feedback loop is the closest analog?
