Egazi womuntu kanye nemisebenzi yabo

egazi Human futhi siqukethe ingxenye ewuketshezi, noma umutsi. Lolu ketshezi ingxenye - isixazululo equkethe ethile micro- futhi macroelements, amafutha, carbohydrate namaprotheni. Amaseli igazi zihlukaniswe ngezigaba ezintathu eziyinhloko, ngalinye elikwazi inezici ayo kwesakhiwo nemisebenzi. Ake sicabangele ngasinye salezi eduze kakhudlwana.

Erythrocyte, noma amangqamuzana egazi abomvu

amaseli abomvu egazi - amaseli kunalokho esikhulu babe ukuma sici kakhulu disk biconcave. I corpuscles obomvu aqukethe awanayo i-nucleus - esikhundleni salo molecule e-hemoglobin. I-hemoglobin - ekhuthaza kunalokho eziyinkimbinkimbi okuyinto yakhiwa ingxenye protein ne-athomu ensimbi ayoni. Amangqamuzana abomvu egazi akhiqizwa umnkantsha.

Amangqamuzana abomvu egazi zinemisebenzi eminingi:

• Negesi lokushintshisana - lokhu ingenye imisebenzi esemqoka kwegazi. Ngqo abantu abahilelekile kule nqubo ithatha nje e-hemoglobin. Ezitsheni ezincane, igazi yamaphaphu is nomoya-mpilo, okuyinto ehlangene insimbi elithwala umoya-mpilo. Lobu buhlobo esethola, ngakho Oxygen uhlala kwamangqamuzana nezicubu inkokhelo lapho idingeke khona. Ngasikhathi sinye, ukulahlekelwa eyodwa yomoya-mpilo athomu sibopha elithwala umoya-mpilo ne-carbon dioxide, okuyinto idluliselwe emaphashini, futhi okukhiphayo imvelo.
• Ngaphezu kwalokho, phezu kwamangqamuzana egazi abomvu sicaciselwe polysaccharide molecule noma antigen ukuthi ukunquma RH neqembu igazi.

egazi White, noma ama-leukocyte

Amangqamuzana amhlophe egazi - kunzima kakhulu iqembu elikhulu amaseli ahlukahlukene, futhi umsebenzi wakhe omkhulu ukuvikela umzimba ezifeni, ubuthi nemizimba angaphandle. La mangqamuzana ane-nucleus, ungakwazi ukushintsha ukwakheka kwalo idlule lendwangu. Akhiwa umnkantsha. Amangqamuzana amhlophe egazi zingahlukaniswa zibe izinhlobo eziningana:

• Neutrophil - iqembu omkhulu wamangqamuzana egazi amhlophe kokuba ikhono phagocytosis. cytoplasm yabo iqukethe zithutha eminingi egcwele enzyme izinto eziphila abakhuthele. Lapho engena phakathi nomzimba we amagciwane noma amagciwane, neutrophil lithuthela cell angaphandle iqopha alibulale.
• Eosinophils - kwamangqamuzana abomvu engeziwe, okuyinto yenza umsebenzi nokuphepha ngokubhubhisa eziphilayo pathogenic ngu phagocytosis. Sebenza mucosa yaleli pheshana yokuphefumula, wamathumbu and uhlelo urinary.
• Basophils - iqembu elincane lamaseli encane okusaqanda, okuyinto iqhaza ekuthuthukiseni ukuvuvukala ukushaqeka anaphylactic.
• Ama-macrophage - amaseli ngenkuthalo ukubhubhisa igciwane izinhlayiya kanye amaseli esibangelwe igciwane, kodwa abe ekuqongeleleni cytoplasmic ka granules.
• Monocytes - zinezikhathi umsebenzi othile, njengoba bengeke bakwazi ukuthuthukisa noma, noma, Ngakolunye uhlangothi, zivimbela ukuvuvukala.
• Ama-lymphocyte - omhlophe egazi obhekene ukuzivikela komzimba. sici wabo ikhono ukwakha ukumelana izilokazane ezincane, esevele okungenani kanye bagamanxela igazi lomuntu.

Ama-platelet I noma thrombocytes

Ama-platelet I - encane, amaseli non-zenuzi kwabantu igazi okusaqanda noma round ukuma. Ngemva yokusebenzisa yangaphandle ulwelwesi yeseli yakha lelivakalako, futhi umphumela waba ukuthi kufana inkanyezi.

Ama-platelet I benezingane eziningi imisebenzi ebalulekile ngempela. injongo yabo eyinhloko - ukwakheka okubizwa ngokuthi igazi ihlule. Esikhundleni abalimele waba ngowokuqala uthole zegazi, okuyinto ngaphansi kwethonya enzyme hormone aqala banamathelane, ukwakha ihlule legazi. Lokhu ihlule plugs isilonda abese eyeka ukopha. Ngaphezu kwalokho, lezi egazi banesibopho ubuqotho nokuzinza izindonga semithambo.

Singasho ukuthi igazi - kuba kunalokho uhlobo kuyinkimbinkimbi futhi enza izinto ezihlukahlukene yokuxhuma izicubu womuntu, yakhelwe silondoloze ukuphila okuvamile.
