Umsebenzi igazi emzimbeni womuntu

Ukuze ososayensi baye wadida umsebenzi igazi emzimbeni womuntu. Imfihlo ukuthi namanje Ukwambula, njengoba ukuphambuka kancane noma ukwephulwa izici eziholela ukufa komuntu esikhathini esifishane.

umsebenzi igazi emzimbeni wehlukile kakhulu. Imisebenzi esemqoka igazi ukuthutha izinto nokudluliselwa umoya-mpilo. Afundwa ngokusebenzisa imithambo yegazi, athwala isamba esikhulu izakhi ukuze umzimba, ikakhulukazi, umoya-mpilo, okuyilona elidingekayo ukuze i- "ukuphefumula" ngayinye zonke izinhlayiya zamangqamuzana aphilayo. Futhi, igazi athwala izakhi zawo wonke umzimba, okuyinto ziyoncibilika emzimbeni ngenxa ukudla. Kulezi neminye imisebenzi kwegazi emzimbeni incike impilo ngamunye ngosuku isimo sakhe sempilo. Kodwa kukangaki sicabanga siyilokho esikudlayo, ukuthi siphuza, futhi bebonke, lokho esiwuhogelayo wona? Mhlawumbe hhayi wonke umuntu uyonika impendulo omuhle kulo mbuzo.

Abaningi izifo zethu zibangelwa yokuthi esingafuni ngempela libe indlela yethu yokuphila njalo. Ngakho-ke, masenze konke esingakwenza uyaqaphela ukuza leli phuzu bese ucabanga ngalokho imisebenzi ye igazi Indlela Ezisithinta umzimba.

Kancane ngaphezu kwesigamu (cishe 55%), ufunyenwe egazini amanzi. Lolu ketshezi ecacile ngokuthi plasma bese uba nombala ugodo ephuzi. Labo abasele abanga-45% yisabelo elalihlala igazi. Red amaseli egazi abizwa ngokuthi amaseli abomvu egazi, emangqamuzaneni egazi amhlophe - egazi amhlophe ke. Kusese ku ukubunjwa igazi nama-platelet, ababiziweyo platelet. Umbala wegazi yethu ixhomeke khona e-hemoglobin. I-hemoglobin ngokuthi sombala nomoya-mpilo nokuba Umbala obomvu. Kokuqhubeka ovela emaphashini ukuze inhliziyo ngokusebenzisa imithambo, i-hemoglobin kakhulu elicwile umoya-mpilo futhi lisakaza kulo izicubu emzimbeni, it has a umbala ocebile abomvu. Igazi-ke ubuyela inhliziyo kusuka ezicutshini zomzimba ngokusebenzisa emithanjeni, futhi nakhu uba nombala mnyama, ngoba e-hemoglobin cishe akukho-mpilo. Ngemva kwalokho, igazi emuva emaphashini, ukuthola ngesikhathi esifanayo umbala obomvu, ngoba ke elicwile ingxenye elandelayo oksijini, futhi inqubo iyaphindwa futhi.

Futhi lokho kuyinto plasma?

Plasma - kuyinto isixazululo aqueous, lapho kukhona kokubili izinhlayiya ezakhayo omubi icala - i-sodium, i-potassium, chlorine, magnesium, kanye nokusungulwa qualitative ambalwa of la ma-athomu efana Ukwakheka lamanzi olwandle. Futhi ekhona plasma izakhi lokugayeka kokudla, amaphrotheni, amavithamini, ama-hormone. Akha-10%, kanti bonke abanye - kuba amanzi.

Kuye ngezidingo umzimba futhi inani kwamaseli egazi njalo elawulwa futhi kulawulwa hemopoietic izitho. Iyini imisebenzi wegazi, futhi, ngokufanelekile, izingxenye main yayo - amangqamuzana abomvu, amangqamuzana amhlophe nezinhlayiya zegazi?

Amangqamuzana abomvu egazi kwandile naphakathi yezingxenye ukuthi aluka egazini. I-hemoglobin kuyinto obukhulu kakhulu abomvu egazi. Imisebenzi erythrocyte wabhala athwala umoya-mpilo kule imithambo yegazi nemithambo ye-carbon dioxide. Amangqamuzana abomvu egazi yizici ebalulekile enqubweni emishinini yokuphefumula futhi ngaleyo ndlela ukumuncwa-mpilo zethu kusuka imvelo bangaphandle kithi.

Yiziphi amangqamuzana amhlophe egazi? Ziyakwazi uhlobo "abavikeli" komzimba ezifweni ezahlukene ukuthi ukungena emgudwini wegazi. Ngezikhathi zidilika amaseli emzimbeni ukwakha izinsalela engadingeki okuyinto leukocyte nazo kusetshenzwe. Amangqamuzana amhlophe egazi zihlukaniswa monocytes, ama-lymphocyte futhi granulocytes.

umsebenzi igazi emzimbeni kubaluleke kakhulu. Lena ngokuyinhloko ukuqinisekisa ngamunye iseli zonke izinto ezibalulekile kanye ukukhululwa kwemikhiqizo imfucuza phila ngaphandle. Zonke lezi amadili amalitha amahlanu kuphela uketshezi, okuyinto izindlela zokuziphilisa yethu.
