internal balance

• Homeostasis is the ability of organisms to maintain a steady internal environment.
• Set point is the the physiological value around which the normal range fluctuates.
• Homeostasis is maintained through feedback mechanisms.
• If homeostasis failed, it can cause imbalance leading to pathology/sickness/permanent damage.
• Feedback Mechanisms helps when we needed to revert back to state if we go pass through our setpoint.
• Positive feedback increases or promote the activity of the whole pathway.
• Positive feedback intensifies response until endpoint is reached.
• An example of positive feedback is blood clotting.
• Negative feedback is counteracting something which reduces excessive response to keep the variable within a normal range.
• An example of negative feedback is body temperature regulatio.
