Homeostasis is attempting to stable the various things in the body and keep the body in normal condition. Homeostasis will occur depending on the mechanisms in the centrally controlling homeostasis in the hypothalamus.
Homeostasis is maintained overall function in the body’s such as temperature, the concentration of iron in the blood, pH concentration and concentration of glucose.
Maintenance of homeostasis is involving negative feedback loops and positive feedback loops to constant in the body.
Negative feedback loops act when inconstant occur in the body and will attempt to bring it back down into set point. The negative feedback loops process including stimulus, sensor, control, and effector.
Two types of negative feedback loops parameters are activated when above the set point and below the set point.
Positive feedback loops are increase the starting signal and keep stimulus until complete, usually found in the processes that need to be continues like childbirth.
Diabetes is caused from failing feedback loops with involved insulin hormone. Insulin is secretion from pancreas in B cells to decrease the level of glucose or sugar in the blood. Which the failing negative feedback loops it is unable for the body to bring high level of sugar in the blood back down to constant.

Homeostasis is significance to keep body functions on equilibrium or stable within the cell. Homeostasis is important for the living thing to maintain a stability when the change condition occurs internal or external of the cell. However, the homeostasis process will continue to adjust until reach to set point.
Feedback regulation is involved the release of hormones in the blood stream, which it is response to the stimulus that occur when change internal environment. There are two types of feedback regulation with is positive feedback regulation and negative feedback regulation.
Positive feedback loop act to accelerate the direction of change.
Negative feedback loop is the most common feedback loop in the body with an act to reverse the direction of change. Article

An innovative approach to understanding eukaryotic evolutionary processes is based on a single state of the life cycle as the primary level. This view presupposes that pre-radionuclide cells by creating micelles themselves, resulting in protected areas. Create chemical reactions to generate energy reduces the entropy sustainability and deliberation by homeostatic mechanisms subsumes diachronic perspectives or for connection time. More than ordinary synchronic views, the semi-static state of homeostasis only retains its original state. The main reason this view has not been used previously is because of widespread prevalence, recognize biological thinking in telephoto.
Homeostasis is constantly around the set point, observed the cell’s environment and ready to reset itself. It is also a reference point for change if necessary to survive in a changing environment.
In other perspectives that homeostasis is statistically based on contemporary depiction of biology, dynamic perspectives are best seen in developmental physiology, especially when excluded in premature infants or reverse is a chronic disease.
The integration of ontogeny and phylogeny is a continuous mechanism of lung homeostasis becoming a unique insight into the underlying mechanisms of evolution that homeostasis can function simultaneously as a stable agent. In book Evolutionary Theory – Unfinished Synthesis of Robert G.B. Reid, points to the paradoxical relationship between homeostasis and evolution, though he failed to claim to have the necessary development dimension.
Homeostasis is determined as the main function that controls various variables to keep the internal condition constant. Examples of homeostasis include the control of body temperature and the balance between acidity and alkalinity. Which it a process that maintains the stability of the internal environment of organisms in response to the external environment fluctuations.
Homeostasis demands a sensor to detect changes in internal conditions that control the effector mechanism that can change that state, and the connection of negative feedback.
All living things depend on preserving the chemical interaction. This included from simplest organisms to the most complex plants and animals, the internal processes work to maintain their condition under control limit and enable these reactions to continue.
Homeostatic control mechanisms have three components that rely on each other for regulated variables. For the first one is a receiver is a component that detects and responds to changes in the environment. After the receptor receive senses a stimulus, then it will signal information to the nucleus, which determines the range at which the variable remains. Nucleus sets the appropriate response to the stimulus. The nucleus sends signals to the effector, which can be cells, tissues, organs, or other structures that receive signals for homeostasis. After receiving the change signal occurs, to correct deviation by pressing or damping using negative feedback.
Negative feedback mechanisms include the reduction of the output or the increase of the organ or system back to the normal range of function. Example is blood pressure control; blood vessels can detect resistance to blood flow when blood pressure increases. Vascular acts as a message to the brain. The brain sends messages to the heart and blood vessels, both of which are effectors. The heart rate decreases as blood vessels increase in diameter. This is called vasodilation change causes the blood pressure to fall back to normal. The opposite occurs when blood pressure decreases, resulting in vascular contraction. (vasoconstriction)
A lot of diseases involve disturbances in homeostasis. For example, when the age of the organism is effective, the control system will decrease because of the loss of the receptor. Inefficiency results in an unstable internal environment that increases the risk of illness, resulting in age-related physical changes.
Homeostatic imbalances such as primary body temperature, high concentrations of blood salts, or low concentrations of oxygen can produce homeostatic reactions, such as heat, thirst or panting, which stimulate behaviour aimed at restoring homeostasis. Note Reflection
