Homeostasis
[edit]Homeostasis is the process of helping an organism maintain a stable internal environment. If the system cannot restore balance or reach equilibrium, it can lead to death. Feedback loops are how the body maintain homeostasis. In feedback loops, there is a stimulus which is the change in the environment detected by the body and a response which is the action made by the body to return to homeostasis. There are two types of feedback loops: Positive feedback and Negative feedback loops. The difference between negative feedback loops and positive feedback loops is that negative feedback reverses or counter-acts the change while positive feedback amplifies or increases the change.
Negative Feedback Loops
[edit]Negative feedback loops involve a response that is the reverse of the change detected (it functions to reduce the change). Example: Exercise causes body temperature to rise (stimulus) ---> Skin becomes flushed and sweating begins (response) ---> Body temperature falls.
Positive Feedback Loops
[edit]Positive feedback loops involve a response that reinforces the change detected (it functions to amplify the change). Example: A person gets a cut (stimulus) ---> The body releases blood platelets to help clot blood (response) ---> The blood platelets will release more platelets which group together to create a clot.
