Homeostasis Refer to tenancity or envirorment arrangement mechanism dinamic balance in (organism body) that constant.

Biosis is life component that include all life organism. Example of biosis component :HumanPlantanimal

Abiosis is dead component like is:Temperatur pHLighthumidityTopographyclimate

The Changes of Envirorment The small change in dinamic envirorment of body can cause dead of cells.examples that will couse a dead of cell although in small size such as :Dehidration essencePoison Temperature change immediately

factorEvery factor has limided account that can infulece dinamic envirorment.example several factor in fluid that need arranged their account.pH - 7,3 - 7,4, different with alimentari channel account,pH is different on limitied place.temperature - 37oC - 39oCGlukosa - 4,4 - 5,5 mmol/dm3Urea - 3,3 - 6,6 mmol/dm3

mechanism

This mechanism arranged by brain especially hipotalamus, if there is stimulus will stimulate coordination of body. This proces will happen continous until dynamic envirormen in body in normal size.2 coordination of body:chemistry coordination- such as hormonNerve Coordination - such as nerve impulse Several proces that include:Umpan balik positif example fever, body will increase fever to kill bacteria and virus.Umpan balik negatif - example in warm , badanbody will arranged for less warm in body

Organs that include in yang arrangement of homeostasis:Heparkidneyskin

Mechanism of homeostasis

Cell of the Immune System

LEUCOCYTESPhagocytes : macrophage, neuotrophil,eosinophilLymphocytes : B cell, T cellAuxillary cell : basophil, mast cell, plateletes (thrombocyt)TISSUE CELLS( liver cells, etc)

IMMUNE RESPONSE I. Innate (natural) immunity. 1. Physical & chemical barrier 2. Phagocytic cells & Natural Killer (NK) Cell 3. Blood protein :complement 4. CytokinesII. Adaptive (spesific) immunity. 1.Humoral Immunity (B cell) 2.Cell Mediated Immunity(Tcell)
