Iiseli igazi lomntu kunye nemisebenzi yazo

Iiseli igazi lomntu kwaye ibandakanya inxalenye engamanzi, okanye serum. Inxalenye ulwelo - isisombululo equlethe umlinganiselo othile ngemithamo kunye macroelements, amafutha, iikhabhohayidrethi kunye neeproteni. Iiseli zegazi yahlulwe amaqela aphambili amathathu, nganye eneyazo iimpawu zayo zokusebenza kunye nemisebenzi. Makhe siqwalasele nganye kwezi kakhulu ngakumbi.

Erythrocytes, okanye iiseli ezibomvu zegazi

Iiseli ezibomvu - Iseli kunokuba enkulu ukuba babe imilo uphawu kakhulu disk biconcave. Le corpuscles ezibomvu ziqulathe inucleus - endaweni yayo zinemoletyhule mpilo. Athwala - a ezimbaxa kunokuba entsonkothileyo nto ndiyibhalayo inxalenye protein i-atom yentsimbi ayoni. iiseli ezibomvu egazini ziveliswa wamathambo.

iiseli ezibomvu azinayo imisebenzi emininzi:

• Gas exchange - oku ngomnye weyona misebenzi iphambili igazi. Ngqo inxaxheba kule nkqubo ithatha nje mpilo. Kwiinqanawa ezincinane, igazi yemiphunga le mpilo, oludityaniswe kunye intsimbi mpilo. Olu lwalamano ingathityazwa, ngoko Ioksijini iiseli zomzimba apho kufuneka khona. Ngaxeshanye, ukulahlekelwa neoksijini atom sibophelela haemoglobin icarbon dioxide, nto leyo ikhutshelwa imiphunga, yaye imveliso kokusingqongileyo.
• Ngaphezu koko, phezu komhlaba iiseli ezibomvu igazi molekyuli ezithile polysaccharide okanye awakwazi ezibonakalisa RH kunye lwegazi.

Iiseli zegazi ezimhlophe, okanye leukocytes

iiseli ezimhlophe zegazi - zako iqela elikhulu iiseli ezahlukeneyo, umsebenzi walo ongundoqo kukukhusela umzimba nxamnye zosulelo, ubuthi kunye namaqumrhu angaphandle. Ezi seli babe inucleus, uyakwazi ukutshintsha ubume balo idlule eli laphu. Ngaba eqalisiweyo umongo wethambo. iiseli ezimhlophe zegazi lungohlulwa lube iintlobo:

• Neutrophils - iqela elikhulu ziiseli zegazi ezimhlophe kokuba ikhono phagocytosis. kukho icytoplasm yabo iqulethe zithutha emininzi egcwele enzyme izinto eziphilayo esebenzayo. Xa zingene umzimba iintsholongwane okanye iintsholongwane, neutrophil ihambisa ukuba ithumba iseli angaphandle latyhaphaka.
• Eosinophils - iiseli ezibomvu, nto leyo yenza umsebenzi ukhuseleko ngokutshabalalisa eziphilayo yayintsholongwane eyosulela yi phagocytosis. Sebenza kwi isifo ye phecana yokuphefumla, kwesisu kunye nenkqubo womchamo.
• Basophils - iqela elincinane iiseli ezincinane okweqanda, leyo uthathe inxaxheba kuphuhliso ukudumba kunye nokothuka anaphylactic.
• Macrophage - iiseli ecela kutshabalalisa amasuntswana ntsholongwane kunye neeseli iintsholongwane, kodwa abe olwenzeka cytoplasmic of granules.
• Monocytes - luphawulwa umsebenzi othile, njengoko unako ukuphuhlisa okanye, okanye, icala, zinqanda inkqubo arhabaxa.
• Lymphocyte - iiseli zegazi ezimhlophe elijongene omzimba. osemqoka yabo ukukwazi ukwenza uxhathiso Cya, esele ubuncinane kanye eyangena egazini labantu.

Zegazi okanye thrombocytes

Zegazi - a, encinane iiseli ezingezo-nuclear of elimbhoxo kwegazi labantu okanye imilo ngeenxa zonke. Emva kusebenze kwi engaphandle inwebu yeseli yakha kwingqikelelo, kunye umphumo ube ngumfuziselo inkwenkwezi.

Zegazi eziliqela imisebenzi ngendlela ebalulekileyo. Zazo eziphambili njongo - ukuyilwa ekuthiwa-ihlwili legazi. Xa indawo abenzakeleyo wayengowokuqala ukufumana zegazi, leyo phantsi kwempembelelo enqanda kunye emzimbeni kuqala lihlale ndawonye, kusekwe ihlwili legazi. Le ihlwili Imigudu enxebeni eyeka ukopha. Ngaphezu koko, ezi seli igazi banoxanduva ingqibelelo kunye nozinzo kweendonga nemithambo.

Sinokuthi igazi - kodwa kunokuba uhlobo nzima yaye ubhetyebhetye yokuqhagamshelana izihlunu yabantu, yenzelwe ukuba baphile ubomi obuqhelekileyo.
