Yiyiphi umbala igazi benegunya oonomadudwane kunye izigcawu?

Yiyiphi umbala igazi le unomadudwane? Lo mbuzo unelungelo lokuba khona, kuba impendulo kuyo kubonakala ukuba abaninzi kakhulu ezingalindelekanga. Igazi zonke izinto eziphilayo, ukutya kwaye sinika iiseli amandla athile omzimba yaye, njengoko siyazi, ukuba bomvu ngebala. Konke ukubonga eziqulathwe erythrocytes (iiseli ezibomvu), ihemoglobin, nto leyo esekelwe entsimbini. Kodwa ke kukho iimeko.

Kweli nqaku siza kukhangela kwenye simanga igazi, abameli ngumntu iqela સંસાધક isisebenzisi le. Umzekelo, thatha unomadudwane kunye yesigcawu. Yiyiphi umbala igazi ezi zidalwa - siza kuzama ukufunda eli nqaku.

igazi Blue?

Liyinyaniso elokuba Akumangalisi, noonomadudwane, izigcawu igazi oluhlaza? Enyanisweni, igazi umbala engaqhelekanga akuthethi ukuba exhasa ezinye imvelaphi "phezulu".

Isibakala sokuba igazi ayiqulathanga ihemoglobin, noonomadudwane, kunye nhla - woogxa balo. Ukuba athwala - izinto yentsimbi aqulethe, nhla ubunjwe zezobhedu. Phezu ukunxibelelana emoyeni element esebenzayo iqalisa ukuvala blue nezihlunu ukunika ioksijini, ulahlekelwa umbala wayo. Ukusuka apha aphethe ngeekatsi igazi ntoni umbala. Yiloo nto arthropods ngenxa yegazi aphuma igazi eluhlaza imithambo - oluhlaza.

Yinto eyaziwayo ukuba haemoglobin equlethwe iiseli ezibomvu plasma. Kodwa hemocyanin unyityilikiswa plasma yegazi. Kukho iimbaza ezigazi iqulethe ihemoglobin kunye hemocyanin, kwaye maxa wambi omnye weyona milenze igazi ithwala ioksijini kunye nezinye wawunikela esikule.

imisebenzi hemocyanin

Hemocyanin, ukuba ngombala yokuphefumla ithwala oksijini arthropods egazini. Le nto ke umdla wokwenene phakathi izazinzulu: kuxhomekeke kubukhulu umzimba ephilileyo 160 ukuya amanxiwa ndibopha bayakwazi ukusebenza kunye nokwenza khona, isenza izithuthi, attachment nokukhululwa ioksijini egazini. Lo mkhuba "njengeqela" izikhanyiso zenzululwazi zingasetyenziswa ukudala "itshintshela" enobuzaza kakhulu eziphilayo - molecule mbi iintlobo ezimbini okanye ngaphezulu esisigxina. Ngelo xesha phakathi kwabo kuya kuba inguqu kunokwenzeka ingathityazwa kwempembelelo zangaphandle - utshintsho ubushushu, utshintsho iasidi, ukukhanya.

Ngoko ke, ukuba beze ne lo mbuzo: "Nguwuphi umbala na igazi yoonomadudwane" - ukuphendula ngokukhuselekileyo - oluhlaza.

umbala igazi izigcawu

Sele isigqibo phezu umbala ngegazi yoonomadudwane, yaye yintoni na malunga nezigcawu? Udidi lwe ezinamaqokobhe yi ezingenambala oluthethwa igazi - le hemolymph. Kutheni kulwelo akukho umbala? Oku kungenxa yokuba ukuba yinxalenye molecule haemoglobin i atom zezobhedu. Mu kuya kwa nshita atom intsimbi okumisele kwemolekyuli haemoglobin, akukho nto enemibala.

Ukongeza ezothutho ukwenzela ukuba kwiiseli emzimbeni, izondlo neoksijini hemolymph kwakhona eminye imisebenzi ebalulekileyo ngokulinganayo kusetyenziswa ukunyusa uxinzelelo lwegazi ngexesha kuhluma kunye nemilenze zobude.

Kweli nqaku siye safumanisa ngeekatsi igazi yintoni umbala kunye yesigcawu. Siyathemba ukuba uya kufumana olu lwazi umdla.
