| What is a negative feedback loop? | A mechanism that reverses a deviation from the set point to maintain balance (e.g., body temperature regulation). |
| Give an example of a positive feedback loop. | Blood clotting or labor contractions during childbirth. |
| What is the role of receptors in homeostasis? | hey detect changes in the internal environment and send signals to the control center. |
| What is the control center in a feedback system? | It processes information from receptors and sends commands to effectors (e.g., brain or spinal cord). |
| What are effectors in homeostasis? | Organs or cells that carry out the necessary response to restore balance (e.g., muscles or glands). |
| What is the normal human body temperature set point? | About 98.6°F (37°C). |
| What happens when homeostasis fails? | t can lead to disease or dysfunction in the body. |
