Umsebenzi igazi emzimbeni womntu

Kuba izazinzulu ebisoloko iphazamisa umsebenzi igazi emzimbeni womntu. Secret ukuba nangoku ngokwenzeka, njengoko ecaleni encinane okanye ukuhlukunyezwa ezi mpawu zikhokelela ekufeni komntu xesha lifutshane kangangoko kunokwenzeka.

umsebenzi negazi umzimba zahlukahlukene kakhulu. Imisebenzi engundoqo igazi ukuthutha izinto kunye nokudluliselwa oksijini. Ajikeleza ngokusebenzisa imithambo yegazi, athwala yonge izondlo umzimba, ingakumbi, ioksijini, oyimfuneko ukwenzela ukuba 'ukuphefumla "ngamnye zonke iiseli eziphilayo. Kwakhona, igazi athwala izakhi wonke umzimba, leyo iqhawulwa emzimbeni ngenxa yokutya. Ukusuka kwezi kunye nezinye imisebenzi igazi emzimbeni kuxhomekeke kwimpilo ngamnye kunye yonke imihla karhulumente yakhe yempilo. Kodwa ngaba thina sicinga nto sidle, into eselwayo, kwaye ngokubanzi, yintoni thina siphefumle? Mhlawumbi asinguye wonke umntu uya kunikela impendulo positive lo mbuzo.

Uninzi izifo zethu zibangelwa isibakala sokuba musa esibi malunga nendlela esiphila ngayo. Ngoko ke, makhe ngabom ukuza kuthi ga ngoku kwaye ucinge kwimisebenzi igazi nendlela ezichaphazela ngayo umzimba.

ngaphezulu kancinane nje kwisiqingatha (malunga nama-55%), mazibalwe igazi namanzi. Olu lwelo ecacileyo ekuthiwa plasma kwaye umbala okhanyayo omthubi. I-45% sisabelo ahlala kuyo igazi. Ezibomvu iiseli zegazi zibizwa ngokuba iiseli ezibomvu, iiseli ezimhlophe zegazi - iiseli zegazi ezimhlophe ngayo. Kukho kuloo nokwakhiwa igazi kunye zegazi, ezo zibizwa ngokuba ziiplatelets. Umbala igazi lethu kuxhomekeke kubukho mpilo. Athwala ebizwa sombala nomoya kwaye ukuba umbala obomvu. Uvela nemiphunga intliziyo ngenxa yegazi, inkoliso ihemoglobin Igcwele oksijini kwaye isasazeka kuyo yonke nezihlunu umzimba, iye umbala obomvu. Igazi ke ubuyela intliziyo ancedisana emzimbeni emithanjeni, kwaye apha inombala mnyama, ngenxa e kwalo phantse ingekho ioksijini. Emva koko, igazi emva emiphungeni, ukuya kwi enye umbala obomvu, ngokuba kokuba igcwaliswe inxalenye elandelayo ioksijini, yaye le nkqubo kwakhona ngokuphindaphindiweyo.

Kwaye yintoni a plasma?

Plasma - yinto isisombululo zolwelo, apho kukho zombini amasuntswana entle nengentlanga wamwisela - sodium, potassium, chlorine, nemagnesium, kunye nokwakheka ezisemgangathweni kunye neenkcukacha zamanani kwezi ion ezifana nokwakhiwa kwamanzi olwandle. Kwakhona khona plasma izondlo emzimbeni, iiprotheni, iivithamini, iihomoni. Benza phezulu malunga ne-10%, kwaye abanye - kuba amanzi.

Ngokuxhomekeke kwiimfuno eziphilayo kunye nenani legazi Ukwakheka ilawulwa rhoqo kwaye kulawulwa amalungu hemopoietic. Yiyiphi imisebenzi igazi, yaye, ngokunjalo, amacandelo ezingundoqo - iiseli ezibomvu, iiseli ezimhlophe zegazi?

Iiseli ezibomvu egazini ekhoyo phakathi izakhi kujikeleziswa egazini. Athwala esixineneyo kakhulu iiseli ezibomvu. Imisebenzi erythrocytes wabha- mpilo kwi imithambo yegazi carbon dioxide. Iiseli ezibomvu egazini amacandelo ebalulekileyo kwinkqubo nokuphefumla ndlela ukufunxeka mpilo-bume lwangaphandle kuthi.

Zeziphi iiseli ezimhlophe zegazi? Basimisela uhlobo 'abavikeli' umzimba izifo ezahlukeneyo engena kwi egazini. Ngamaxesha athile ukuwa iiseli emzimbeni ukwenza iintsalela ezingafunekiyo apho leukocytes nabo phambili. iiseli ezimhlophe zegazi zahlulwa zibe monocytes, lymphocyte kunye granulocytes.

umsebenzi igazi emzimbeni kubaluleke kakhulu. Oku ikakhulu ukuqinisekisa ngamnye iseli zonke izinto ezibalulekileyo kunye nokukhululwa imveliso inkunkuma Uzalathise. Zonke ezi nezahlulo emihlanu kuphela iilitha ulwelo, nebonelela ubomi bethu.
