Erythrocyte egazini

I-erythrocytes egazini yileli iiseli eziphambili. Ezi zinto ziphezulu kunezinye iifom zefom, zithathwa ndawonye. I-Erythrocytes egazini ivela ngendlela yeediski eziqhelekileyo ezinomqolo obanzi. Ngenxa yesi sakhiwo, ezi ziko zenziwa ngokugqithiseleyo nge-carbon dioxide kunye ne-oksijini ngexesha lokudlula kwi-system circulatory system.

Ukwakhiwa (ukuhlaziywa rhoqo) kwe-erythrocytes kumnxeba obomvu obomvu kwenzeka phantsi kwefuthe le-erythropoietin (i-hormone ye-renal). Iingxenye ezimbini kwisithathu zale mizimba ziqukethe i-hemoglobin (iproteinyini enezinyithi). Umbala obomvu wale protoyini unquma umbala wegazi ngokubanzi kunye neeseli ezibomvu zegazi ngokukodwa.

Ubomi bokuba "iiseli eziphambili" ziyikhulu elinamanci mabini. I-Erythrocytes elinepeni kunye nesibindi iyachithwa. Ngomnatha wethambo kukho ukuhlaziya rhoqo. Ngaloo ndlela, ukutshatyalaliswa kwemizimba "ephazamisekileyo" ayichaphazeli ukugxilwa kwabo bonke umzimba.

I-Erythrocytes e-blood supply tiscues ene-oksijeni, evela kubo, ithwala i- carbon dioxide emapapeni , kwaye ihambisa ama-amino acids ukusuka kwimizimba yokugaya izicubu. Ukongezelela, la maseli egazi enza umsebenzi okhuselayo. Benza ukuchithwa kweentengiso (i-absorption) ye-toxins kunye nama-antigens, ukuthatha inxaxheba ekuphenduleni kwe-immunity, banomthwalo wokugcina igazi, i-alkaline kunye ne-acid balance.

Isiqhelo se-erythrocyte egazini sinqunywe ngoluhlu lokuhlaziywa kwebhubhoratri. Uxinzelelo oluqhelekileyo lwale mizimba luvela kwi-4 ukuya kwi-5.1x10 nganye ngeyure kubantu abadala. Kubantwana babo kwinqanaba lixhomekeke kwiminyaka yobudala. Kwiiveki zokuqala zobomi bomntwana, xa wenza uhlalutyo lwe-erythrocyte egazini, umgangatho uvela kwi-4.3 ukuya ku-7.6x10 ngeyure nganye, ngexesha leenyanga-ukusuka kwi-3.7 ukuya ku-5.6x10 ngelitha nganye, kwiinyanga ezi-6 ukuya kwiinyanga-ukusuka kwi-3.5 ukuya 4.8х10 ngeyure. Xa umntwana efikelela kwiminyaka elishumi elinesibini, isibonakaliso sisuka ku-3.5 ukuya kwi-4.7x10 ngelitha nganye. Xa uneminyaka elishumi elinesithathu nangaphezulu kubantwana, uxinzelelo oluqhelekileyo luhambelana nemilinganiselo evamile kubantu abadala.

I-Erythrocytes egazini ephezulu (i-erythrocytosis) ifunyenwe ngezifo ezingaqhelekanga zesimiso se-hematopoietic (i-erythremia, umzekelo). Umgangatho ophezulu ukwagcinwa kunye nokuphuhliswa kwezifo zokuphefumula, ubukho bentliziyo.

Nangona kunjalo, kwiimeko ezininzi, umxholo ophezulu weeseli ezibomvu zegazi kubonisa ukuqina kwigazi.

Kwiimeko ezinjalo zibangele ukusetyenziswa kwamanzi aphantsi asemgangathweni. Kwimeko apho umzimba uchithwa klorinated, amanzi angcolileyo okanye akhuphe ngokukhawuleza, ekusebenziseni kwakhe kufuneka achithe amandla amaninzi.

Esinye isizathu, ukunyuka kwegazi kubhekisela ekungabikho kwamanyonge. Ngoncedo lwale miba, inkqubo yokugaya i-carbohydrates, lipids kunye neeprotheni zenziwa. Inomxholo engapheliyo ye-enzyme ifaka inyaniso yokuba iimveliso ezingaphantsi kwe-oxidized enter the blood. Oku, kubangela ukuba i-oksijini yindlala yamathambo kunye neeseli zomzimba, ukuphulwa kwenkqubo yezinto eziphilayo.

Isizathu esisoloko sinyusa igazi sinyusa umzimba. Oku kuya kwenzeka kwimozulu eshushu. Kufuneka kuqatshelwe ukuba amanzi aneluncedo kuphela kwifom yalo ecocekileyo. Xa kwakhiwa itiye okanye isobho, lisebenza njengesisombululo.

I-Erythrocytosis ingahlakulela ngokungabikho kwamavithamini, eyimfuneko yokuveliswa kwamahomoni kunye ne-enzyme, kunye nokuvezwa kwimizi engozi.

Kufuneka kuqatshelwe ukuba ekuhlalutyweni kwegazi, umgangatho webala, ubungakanani kunye nefriji ye-erythrocytes ibaluleke kakhulu. Ngoko, umzekelo, ukungabikho kwamavithamini, i-folic acid kunye neyinyithi emzimbeni kubonisa isimo se-oval yale mizimba. Kwimeko yokufumanisa i-erythrocyte yesimo esingavunyelwanga (iphukile okanye ijikelezwe ngamaphethelo), kukho inkqubo ye-oxidation esebenzayo emzimbeni.
