Negative feedback loops are feedback mechanisms that help maintain stability or homeostasis by dampening or counteracting changes. Here are some examples of negative feedback loops: Blood glucose regulation.Blood glucose levels rise after eating. This rise triggers the release of insulin, which helps ...

This thinking-aloud study extends insight to the field by providing causal loop diagrams to examine reasoning related to feedback loops. High school students (N = 30, 14鈥 16 years) analysed system behaviours and regulative measures based on the regulation of blood glucose. We developed a ...
1. Regulation of blood glucose level The level of glucose in the blood is controlled by a negative feedback mechanism. If the blood glucose level increases beyond the normal range, more glucose is absorbed in the intestine and stored in the form of glycogen in the liver. The conversion and ...

Examples of processes that utilise negative feedback loops include homeostatic systems, such as:Thermoregulation(if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when leve...
Positive feedback loops are less common that negative feedback loops within the body. Blood clotting is an example of a positive feedback loop where the outcome of the hormone is intensified (blood sticks together more and more until a clot is formed). An...

When the negative feedback loop that helps stabilize blood glucose levels fails, the person is said to have a disease called diabetes. Many diseases, like heart diseases, involve life-threatening positive feedback loops. For example, when a small part of the heart tissue dies, inadequate amount...
