The womukati ezvinhu ane Muviri kukosha kwayo

Mashoko okuti "milieu sisustus" akazviratidza nemhaka physiologist French Claude Bernard, vaigara XIX remakore. Pamabasa ake, akaisa Kumikidzo chokwadi kuti chinodiwa kuti upenyu muviri ndiko kuchengeta nguva dzose pamusoro pezviri kwezvakatipoteredza. Urongwa uhwu akava hwaro dzidziso homeostasis, rakanga akagadzira pashure (muna 1929), musayendisiti Walter Cannon.

Homeostasis - hama simba nguva dzose pamusoro womukati kwezvakatipoteredza, uyewo vamwe kunofambira mberi vasiri mabasa. Milieu sisustus vakaumba mvura maviri - intracellular uye extracellular. Chokwadi ndechokuti sero ose ane muviri mupenyu ane chaizvo basa, saka inoda kuramba dziripo zvinovaka muviri uye okisijeni. Iye anofungawo kudiwa kuramba kubviswa metabolic zvigadzirwa. Zvakafanira zvinoriumba anogona ichipfuura Kamudzira chete ichiputswa mamiriro, ndokusaka ose sero rinenge Urume crow, izvo chinayo zvose zvakafanira ayo inoshanda. Kwazvinoita Yaunoti extracellular fluid uye nezvokuvandudzika 20 muzana uremu muviri.

The womukati ezvinhu ane muviri, raiumbwa extracellular mvura kuitika:

• node (chikamu zvinyama Urume) - 2 L;
• Blood - 3 L;
• interstitial Urume - 10 L;
• transcellular mvura - anenge 1 L (izvozvo rinoumbwa cerebrospinal, pleural, synovial, ocular mvura).

Vose vane zvakasiyana sezvamunoita uye siyana panyaya functionality ehupfumi. Uyezve, dzomunyika ezvinhu womunhu muviri angava musiyano muduku pakati aibuda mwero zvinhu zvavo chionekeso. Nokuda wevasungwa uyu anogara kwazvo muchikwidza nokuderedza inzwi. Somuenzaniso, kuwanda kweshuga muropa mukuru Ingasiyana kubva 0,8 kusvika 1,2 g / l. Pakadaro, kana ropa rine zvakawanda kana zvishoma zvimwe zvinhu kupfuura zvakafanira, inoratidza kuvapo chirwere.

Sezvatotaurwa, milieu sisustus somumwe zvinoumba rine ropa. Inoitwa plasma, mvura, mapuroteni, mafuta, shuga, urea uye chicherwa munyu. chikuru dziri dzayo ropa midziyo (capillaries, mutsinga, arteries). Zvinonzi inoumbwa ne Absorção de Água kwemapurotini ropa, makabhohaidhiretsi, mafuta, mvura. chikuru basa Its ndiye ukama kwezvakatipoteredza nezviremera, kukurukura kuti nhengo zvakafanira zvinhu, kubviswa zvigadzirwa kubva mumuviri kuora. uyewo ine unodzivirira nerevane humoral.

Zvinyama Urume ine mvura ukaparadzawo mairi zvinovaka muviri, CO _2, O _2, uyewo zvibereko dissimilation. Riri mune magwanza pakati masero uye zvinyama achiumbwa tichiregeredza plasma. Zvinyama Urume ndiyo zvenguva pakati ropa uye masero. Iye chirwere ropa mukati masero ari O _2, chicherwa munyu, muviri.

Node ine mvura ukaparadzawo mairi Organic zvinhu. Riri mune nhengo dzinobudisa ino kuti chinosanganisira node capillaries, tsinga, fused kune ducts maviri uye ichayerera kupinda vena cava. Zvinonzi akaumba nokuda zvinyama Urume mu pouches, vari kumigumo node capillaries. The chikuru basa iri kudzorera node rinenge mvura iri muropa. Uyezve, filters uye disinfects ari tishu Urume.

Sezvo tinogona kuona, muviri womukati zvakatipoteredza kutaridza vasiri, panyama uye makemikari, ukuwo, uye masero ezvinhu chokuita chinhanho munhu mupenyu.
