Njani iqela yegazi. Uhlobo lwegazi ixhaphakileyo ehlabathini

Igazi yahlulwe ngokwamaqela ngokubhekisele kubukho kuwo antigen ezithile kunye antibodies noko. Kukho amaqela ezine eziphambili zayo 0 (I), ezi A (II), Ngo (III), kunye AB (IV). Nganye kwezi liyangqinelana nenani, kwaye incwadi ibonisa ukungabikho okanye ubukho nezakhi ezithile. Kwakhona umlinganiselo wokuhambelana.

Xa abantu, yemfuza amaxabiso igazi musa ukutshintsha ubomi. Le ubuntu identifier eqinisekileyo ukuba abantwana ilifa kubazali babo. Amaqela sakudala ngaphezu ngobuzwe okanye uhlanga. Umahluko omkhulu phakathi kwabantu ezahlukeneyo, ngokutsho abaphengululi amaninzi, ukuba imvelaphi yobuhlanga kunye ibala lolusu, eyile nokwakheka igazi.

Iqela igazi luqhelekileyo - kuqala. Ngokuba igazi oko yeyona ifanelekileyo kuba akukho nto ziqulathe i iantigens. Eyesibini efanelekileyo kuphela abantu efanayo kunye neqela yesine ngenxa phambi awakwazi A. Eyesithathu efanelekileyo kuphela abanini yesithathu neyesine, kwaye enye yokugqibela zingathululelwa kuphela kubantu neqela gazi.

Nangona kunjalo, akukho kuphela ubukho okanye ukungabikho antigen, kodwa ke RH into. Kuchazwa bubukho iiprothini ebomvu legazi komhlaba. Ukuba kunjalo, i-RH - HIV, kwaye ukuba akukho - akukho. Malunga ne-85% labemi behlabathi abe RH into entle. Umzekelo, uhlobo lwegazi wesithathu engalunganga eqhelekileyo ngaphantsi lee HIV. Kukwasebenza kwanjalo kuyo enye.

Okokuqala, uhlobo lwegazi iqhelekileyo, eyafunyanwa-45% yabantu ehlabathini. Okulandelayo ukuze ke abanye. Rare ke iqela yesine. Ukuba sithathe ingqalelo RH into, iqela igazi ixhaphakileyo - ezakhayo yokuqala kakhulu ezinqabileyo - ezimbi wesine.

Group kunye RH kufuneka ziqwalaselwe ngexesha ucwangciso lokukhulelwa. Ukuba umbungu ilifa uyise ezizakubonisa ingahimbiselani ligazi sikanina, ngexesha lokukhulelwa inokuba ingxaki. Noko ke, yesilungu ikwazi ngokupheleleyo ukunqanda kubo.

Igazi lenzeka amawaka eminyaka kwaye ezinxulumene kunye nophuhliso abanamajoni omzimba esiswini. Blood Group 1 entle ngamakhoboka yaba lonke uluntu. wokugaya ngoko yaba yeyona apha naphaya ukugaya protein inyama. Ngoko ke, abantu kolu didi zisekhona acid yejusi esiswini, kwaye abathanda ukuba isilonda Peptic. Lokuqala - nangoku uhlobo lwegazi ixhaphakileyo. Ngenxa inani labantu ukwanda inyama ngenxa eshotayo baso zifikeleleke kangako, ngoko abantu banoxanduva waqalisa ukutya isityalo. Oku umgangatho igazi, nto leyo eyakhokelela ekubeni ukuvela kwamanye amaqela ukuba olinike abantu iimpawu ezininzi luncedo.

Umzekelo, abanini igazi ukusuka genome ziqhelana ngakumbi ebomini kwihlabathi lanamhlanje. Eli sofuzo ngaxa lithile yaba usisiqinisekiso ukusinda yabantu ngexesha isibetho ezoyikekayo nekholera. Abantu zithako igazi ngaphantsi ndlongondlongo yaye zoqhagamshelwano ngakumbi, nto leyo ebanceda ndizive kwabo ekuhlaleni.
