Homeostasis
Homeostasis is a state of balance.
Controls and maintain the PH in a certain range in the blood.
Controls and maintain the glucose of the blood in a certain range.
Controls and maintain the internal temperature og the body in a certain range.
Negative Feedback
This type of feedback loop in the human body resists or reverses the process when conditions go beyond the range.
Ectotherm
Positive Feedback
Positive feedback stimulates and intensifies a physiological shift of the body, which ultimately takes the individual well outside the normal range. This kind of body feedback is natural if a certain endpoint occurs.
Example: Blood pressure, PH in the blood.
Example: Lactation, blood clotting
Is an organism with comparatively low or very zero significance of internal physiological heat sources in the body's temperature regulation. Ectotherms can function at economical metabolic levels since they depend on ambient heat sources.
Endotherm
|
Unlike ectotherms, endotherms control their own body temperature by internal metabolic processes and typically hold the inner temperature to a restricted extent. The normal metabolism of the animal normally generates heat, but an endotherm creates extra heat by shivering in conditions of extreme cold or low activity.

Example: Photosynthesis (chlorophyll is used to react to carbon dioxide plus water plus energy to make glucose and oxygen)
Examples of Ectotherm: Lizards, Frogs, snake, etc.
