Wannan arziki ya zama tushen ga ka'idar homeostasis, wadda aka kirkireta daga baya (a 1929), masanin kimiyya Walter igwa.

Homeostasis - zumunta tsauri uri na ciki yanayi, kazalika da wasu a tsaye physiological ayyuka. Milieu intérieur kafa biyu taya - kwayuka da extracellular. Gaskiyar ita ce, kowane cell na wani rai kwayoyin yana da wani takamaiman aiki, don haka shi yana bukatar akai wadata da na gina jiki da kuma oxygen. Ta kuma ji da bukatar m kau na na rayuwa kayayyakin. Dole aka gyara iya wuce ta cikin membrane kawai a narkar da jihar, wanda shi ne dalilin da ya sa kowane cell nama ruwa wanke, wanda kunshi kome zama dole domin ta aiki. Yana da dangantaka da abin da ake kira extracellular ruwa, kuma shi lissafinsu kashi 20 cikin dari na jiki nauyi.

A ciki yanayi na kwayoyin, kunsha na extracellular ruwa, hada da:

• Lymph (ɓangare na nama ruwa) - 2 l;
• Jini - 3 l;
• interstitial ruwa - 10 l;
• transcellular ruwa - game da 1 L (shi ne hada cerebrospinal, pleural, synovial, ocular ruwa).

Bugu da ƙari, ciki yanayi na jikin mutum na iya samun kananan bambanci tsakanin kwarara kudi da abubuwa da kuma su samu. Saboda wannan taro ne kullum fluctuating. Alal misali, yawan sukari a cikin jini na fara tasawa iya Range daga 0.8 zuwa 1.2 g / l. A wannan yanayin, idan jini ya ƙunshi fiye ko žasa da wasu sinadaran fiye da zama dole, shi ya nuna gaban cuta.

Kamar yadda muka rigaya muka gani, milieu intérieur matsayin daya daga cikin aka gyara ƙunshi jini. Ya kunshi jini, ruwa, gina jiki, mai, glucose, urea da kuma ma'adinai salts.

Ta shan wahala daga jini a cikin sel na Yã _2, ma'adinai salts, gina jiki.

Lymph kunshi ruwa da kuma narkar da a cikinta kwayoyin abubuwa. An located a cikin lymphatic tsarin da ta ƙunshi Lymph capillaries, jini, Fused zuwa biyu ducts kuma daga ƙarƙashinsu a cikin vena cava. An kafa saboda da nama ruwa a pouches, wanda suke a cikin iyakar Lymph capillaries. Babban aiki shi ne ya koma da Lymph nama ruwa a cikin jini. Bugu da kari, shi tace da disinfects da nama ruwa.

Kamar yadda zamu iya gani, da jiki ta ciki yanayi ne mai sa na physiological, jiki da kuma sinadaran, bi da bi, da kuma kayyade yanayin da shafi viability na halitta mai rai.
