Animal organs and systems are constantly adapting to internal and external changes through a process called homeostasis ("homeostasis").

These changes can occur in blood glucose or calcium levels or at an external temperature. Homeostasis means maintaining the dynamic balance of the body. It is dynamic because it is constantly adapting to changes in the human system. This is a balance because body functions will be maintained for a certain period of time. Even apparently inactive animals can maintain this homeostasis.

A goal balance of a steady state process refers to maintaining a balance around a point or value calledSet point. Although there are normal fluctuations from the fixed point, the human system will usually try to return to this point. Changes in the internal or external environment are called stimuli and are detected by the recipient. The system response is to set the deviation coefficient to the set point. For example, if the object heats up too much, make adjustments to cool the animal. When blood sugar rises after a meal, blood sugar levels can be adjusted by obtaining or storing nutrients. Some fabrics you will need to use later. Balance Management When an animal's environment changes, it must be adjusted. The shelter recognizes aThe change in the environment, then sends the signal to the control center (in most cases to the brain), and the control center produces a response called a transmitter. Effects are secreted muscles (contraction or relaxation) or glands. Maintain balance using a negative feedback loop. The positive feedback loop does not balance the body, but it may need to survive. The balance passes through the mammalian nervous and endocrine system. Negative Feedback Machine Any homeostasis process that changes the direction of the stimulus is a negative feedback loop. It can increase or decrease the stimulus, but the stimulus cannot continue as the recipient feels it. In other words, if the levelToo high, the body does something to lower it; On the contrary, if the level is too low, the body does something to increase the surgery. Hence the term negative feedback. Remember that the animal maintains the blood sugar level: when the animal eats, the blood sugar level rises. It is seen by the nervous system. Special cells in the pancreas notice this, and the hormone insulin is secreted by the endocrine system. Insulin lowers blood sugar levels, which can lead to negative feedback patterns. However, if the animal does not eat and the blood sugar level drops, it will be detected in another group of cells in the pancreas and the hormone glucagon will be released, fromWhich will raise the glucose level. The negative feedback loop is the main mechanism used for balancing.
