Study Notes

Homeostasis Regulation

  • Homeostasis is a control mechanism in the body, similar to feedback control in engineering.
  • In homeostasis, a sample of what is being produced is used as a signal to control the production to a desired level.
  • The system takes a sample of the production to regulate it.

Feedback Types

  • There are two types of feedback in homeostasis regulation: positive and negative feedback.
  • Negative Feedback: When an increase in the amount fed back decreases the production, and a decrease in the sample increases the production.
