Indlela ukunquma igazi pH. -PH igazi lomuntu: kuyinsakavukela kanye nokusuka

Igazi iyona ebaluleke kakhulu imvelo yangaphakathi zomzimba womuntu, it yakha izicubu ketshezi zezinzwa. eziningi eemfundweni biology ukhumbula ukuthi khona plasma yegazi kanye izici eziningana ezinjengolwazi leukocyte amaseli, izinhlayiya zegazi kanye amangqamuzana abomvu egazi. Yena njalo ukhiphela ngokusebenzisa izitsha, ongakayeki namanje umzuzwana bese ngaleyo ndlela usinika umoya-mpilo, zonke kwezitho nezicubu. Uneziqu ikhono ukubuyekezwa ngokushesha uyayidiliza amaseli ubudala futhi ngokushesha yakha entsha. Iqiniso lokuthi pH okunjalo futhi asidi izinkomba igazi, impilo yabo kanye nomthelela isimo umzimba, kanye nendlela ukukala igazi asidi silungise ne ukulungiswa ekudleni, uzofunda kusukela kulesi sihloko.

umsebenzi wegazi

• Okunomsoco. Igazi elingenawo umoya usinika zonke izingxenye zomzimba, ama-hormone, ama-enzyme, ukuvumela ukusebenza ngokugcwele wonke umzimba iyonke.
• Breathing. Ngokusebenzisa kwegazi, umoya-mpilo ongena ovela emaphashini ezicutshini futhi isikhutha iseli okunalokho - emaphashini.
• Regulatory. It is kulawulwa ukulethwa kwezakhi ngegazi emzimbeni, wayefisa lokushisa ezingeni inakekelwa futhi elawulwa inani hormone.
• Homeostatic. Lokhu umsebenzi inquma ukungezwani zangaphakathi nebhalansi emzimbeni.

Umlando omncane

Ngakho, kungani kudingeka utadishe pH igazi labantu noma, njengoba zibizwa kanjalo, asidi igazi? Impendulo ilula: ke Liyindawo ukubaluleka ofiselekayo uzinzile. It yakha inkambo edingekayo izinqubo redox zomzimba womuntu, umsebenzi wayo enzyme, ngaphezu, ukushuba zonke izinhlobo izinqubo umzimba. Esikhathini acid-base ezingeni lanoma yiluphi uhlobo oluthile loketshezi (igazi kuhlanganise) kuthinta inani hydrogen asebenzayo izinhlayiya ezikuyo. Ungakwazi ukuqhuba ukuhlolwa ukucacisa pH ketshezi ngamunye, kodwa lesi sihloko sikhuluma pH igazi lomuntu.

Okokuqala, igama elithi "i-hydrogen Inkomba" ubonakele ekuqaleni kwekhulu lama-20 futhi wawenza efanayo izinga pH oyisazi Denmark - Soren uPetru Lauritz inkonzo. Afakiwe kubo asidi ukuzimisela uhlelo uketshezi kwadingeka division by amayunithi 0 kuya 14. It kulingana nenani hlangothi 7.0. Uma i-pH we noma yiluphi uketshezi kuba ngaphansi kwenani elicacisiwe, kusho ukuthi kwakukhona ukuphambuka ohlangothini "asidi", futhi uma ngaphezulu - ohlangothini "ayinayo". Ukuzinza ibhalansi acid-base the human ukwesekwa umzimba okuthiwa sesikhashana izinhlelo - ketshezi, okuyinto zizinze kuma-athomu ye-hydrogen, ukuzigcina amanani edingekayo. Futhi ubasize ngale bokuphila isinxephezelo izindlela - umphumela kwesibindi, nezinso emaphashini. Ndawonye bebuka, ukuthi ukubaluleka kwegazi pH lahlala uhla evamile, indlela kuphela umzimba ngeke usebenze ngokushelela, ngaphandle kokuphazamiseka. Umthelela enkulu ngale nqubo kulula, ngoba ukukhiqiza omningi ukudla esidi (zivela ifomu-carbon dioxide), futhi ukusekela umthamo yazo zonke izinhlelo eziyishumi nemitshingo. Izinso ukuhlanganisa nokuhlukanisa ifomu hydrogen izinhlayiya, bese ubuyela egazini, i-sodium ion futhi Bicarbonate, futhi isibindi izinqubo ezithile futhi aqede acid okuyinto umzimba wethu ayisadingeki. Akufanele sibakhohlwe mayelana nomsebenzi wokugaya ukudla, bona nabo banengxenye ekuvikeleni nokugcinwa acid-base ezingeni ukuqinisela. A umnikelo lokhu emangalisayo omkhulu: ngenhla izitho ukukhiqiza ayo wokugaya ukudla (isib esiswini), okuyinto angene ane-alikhali noma ukuphendula ene-asidi.

Indlela ukunquma igazi pH?

Ukumeda wegazi pH wenziwa indlela electrometric le njongo isetshenziswa a electrode ethize ezenziwe ngengilazi, esichaza inombolo hydrogen ion. Umphumela kuthinta isikhutha eziqukethwe egazi. Ukunqunywa igazi pH kungaba kwenziwe egunjini lokucwaninga esibhedlela. Uyoba kuphela ukuze nginikeze indaba for ukuhlaziywa, futhi kudingeka lwemithambo kuphela noma capillary igazi (fingerstick). Ngaphezu kwalokho, igazi lwemithambo ihlinzeka ngemiphumela ethembeke kakhulu ngoba ukubaluleka acid-ane-alikhali kwalo njalo kakhulu.

Wazi kanjani ukuthi igazi laso pH yakho ekhaya?

Yiqiniso, indlela eyamukelekayo kakhulu isazoqhubeka isikhalazo emtholampilo oseduze ukuze uthole ukuhlaziya. Ikakhulu ngemva udokotela uzokwazi ukunikeza kuveze ngokwanele imiphumela kanye neziphakamiso. Kodwa kuze kube manje, yathela eziningi amathuluzi ezokunikeza impendulo eqondile embuzweni ukuthi ukucacisa pH we igazi ekhaya. Inalidi thinnest kuhlaba isikhumba futhi kweso ukuthola inani elincane ezibonakalayo noma microcomputer, elisetendeni iyunithi, ngokushesha wenza zonke izibalo ezidingekayo futhi ubonisa yi esikrinini. Konke kwenzeka ngokushesha futhi ngaphandle kobuhlungu. Ukuze uthenge idivayisi enjalo kungaba ngendlela imishini kwezokwelapha okukhethekile esitolo. Okukhulu ekhemisi amaketanga kungaletha kule yunithi oda.

I-asidi igazi labantu: evamile futhi ngeziphambeko

PH evamile wegazi ibala 7,35 - 7.45 amayunithi, ukuthi izinkomba umuntu enempilo, okubonisa ukuthi unayo ukuphendula kancane ane-alikhali. Uma lesi sibalo kuyehla kanye PH ngezansi 7,35, udokotela kwenza ukuxilongwa "lactic". Futhi uma izibalo ngaphezu evamile kuba umbuzo zokushintsha imithetho ukuze ohlangothini ane-alikhali, ibizwa ngokuthi alkalosis (lapho Inkomba ingaphezu kwe 7.45). Umuntu Kufanele sikuthathe ngokungathí sina ezingeni pH emzimbeni wakho, ngoba ngeziphambeko amayunithi ezingaphezu kuka-0.4 (esingaphansi 7.0 noma ngaphezulu kuka 7.8) usevele kubhekwe aluhambisani nawo ekuphileni.

lactic

Endabeni uma uphenyo laboratory wembula lactic endaweni nesineke, zingase zibe Indlela khona isifo sikashukela, anoxia noma isimo noma ukushaqeka elihlobene ne esigabeni sokuqala ngisho izifo ezimbi nakakhulu. lactic Easy asymptomatic, futhi ingakwazi ukuzwa kuphela endaweni yokucwaninga, ukulinganisa pH igazi lakho. ifomu Sinzima lesi sifo kuhambisana ukuphefumula okusheshayo, isicanucanu nokuhlanza. Uma lactic lapho asidi ezingeni umzimba lize liba ngaphansi kwe 7.35 (pH igazi kuyinsakavukela - 7.35-7.45), kuzomele uqale imbangela ukuphambuka enjalo, futhi nalo isiguli sidinga uketshezi reception soda ngaphakathi njengoba isixazululo. Ngaphezu kwalokho, kubalulekile kuleli cala ukubona onguchwepheshe - lo owelapha noma udokotela ambulensi.

alkalosis

Imbangela alkalosis umzimba kungase kube ukuhlanza eziphikelelayo (ngokuvamile uma ubuthi), okuyinto kuhambisana nokulahlekelwa abalulekile acid juice esiswini, noma ukudla esiningi ukudla ezibangela supersaturation umzimba alikhali (imikhiqizo yemifino, imikhiqizo yobisi). Kukhona ezihlukahlukene ezifana ephezulu acid-base balance, njengoba "alkalosis zokuphefumula." Uyakwazi ukuthola ngisho umuntu enempilo ngokuphelele futhi eqinile ubendle kakhulu sezinzwa, ukuzikhandla ngokweqile, kanye ezigulini zithambekele akhuluphele noma iphika e abantu abasheshe bacasuke izifo zenhliziyo nemithambo yegazi. ukwelashwa alkalosis (njengoba kwenzeka nge lactic) iqala kokususwa Lo msindo ubangelwa. Futhi, uma kunesidingo ukubuyisela pH ezingeni kwegazi labantu, lokhu ingatholakala ephefumula Izingxube aqukethe-carbon dioxide. Kuyadingeka sokusukuma futhi ngisho izixazululo potassium, ammonium, calcium insulini. Kodwa self-wahlanganyela Kunoma yikuphi akunakwenzeka, zonke manipulations abazenzi ngaphansi kokuqondisa kochwepheshe, ngokuvamile isiguli sidinga esibhedlela. Zonke izinqubo ezidingekayo ebekwe udokotela-Umeluleki.

Yini ukudla ukwandisa asidi yegazi

Ukuze ugcine ngaphansi kolawulo (evamile 7.35-7.45) pH igazi, udinga ukudla ngendlela efanele futhi ukwazi ukuthi ukudla ukwandisa asidi, futhi yini - the ayinayo emzimbeni. Ukudla ukwandisa ezingeni asidi, zihlanganisa:

• inyama kanye nenyama imikhiqizo;
• inhlanzi;
• amaqanda;
• ushukela;
• ubhiya;
• imikhiqizo kanye nemikhiqizo ebhikawozi yobisi;
• pasta;
• iziphuzo ezinoshukela carbonated;
• utshwala;
• nogwayi;
• usawoti;
• okokunandisa;
• imithi elwa namagciwane;
• cishe zonke izinhlobo okusanhlamvu;
• iningi ubhontshisi;
• uviniga zakudala;
• kwasolwandle.

Kwenzekani uma i-asidi lenyuka igazi

Uma yokudla komuntu njalo kuhlanganisa imikhiqizo engenhla ke ekugcineni lokho kuyoholela kwehle amasosha omzimba, kolwelwesi futhi pancreatitis. ngokuvamile Umuntu onjalo abambe abandayo futhi ukutheleleka ngoba umzimba iba buthakathaka. esiningi ngokweqile acid emzimbeni wesilisa kuholela ubuthakathaka kanye nenzalo, kusukela isidoda ezidingekile umsebenzi imvelo ane-alikhali futhi esidi abachitha kubo. asidi Ukwandisa isidumbu sowesifazane futhi nomthelela ongemuhle umsebenzi zokuzala, ngoba nge okwandisa asidi of isidoda emomozini engene ke, ukufa, ayikwazi ukuthola esibelethweni. Yingakho-ke kubalulekile ukuba silondoloze ezingeni njalo womuntu igazi pH ngaphakathi kwezinkambiso aqine.

Imikhiqizo ezenza ukusabela igazi ane-alikhali

Ayinayo amazinga emzimbeni womuntu okuthuthukiswa ukudla:

• ikhabe;
• ikhabe;
• zonke izithelo ezisawolintshi;
• isilimo esidliwayo esinamagatsha anamanzi;
• umango;
• sasigaya upopo;
• isipinashi;
• parsley;
• amagilebhisi amnandi, lapho kungekho bone;
• asparagus;
• amagonandoda;
• omisiwe;
• apula;
• amabhilikosi;
• ayo ngokuphelele yonke imifino;
• ubhanana;
• ukwatapheya;
• ginger;
• nesweli;
• amapentshisi;
• nectarines;
• amakhambi amaningi, kuhlanganise nemithi.

Uma umuntu ibusa isilwane namafutha amaningi kakhulu, ikhofi, utshwala kanye amaswidi, umzimba "peroxidation", okusho ukuthi ukwanda kwezimo imvelo azibukhali ane-alikhali. Ukubhema ukucindezeleka njalo futhi zibulale igazi pH. Kulokhu azibukhali imikhiqizo umzimba kungukuthi isuswe kuze kube sekupheleni, kodwa ngesimo nosawoti buthelela nokusaketshezi extracellular nezihlanganiso bangaba imbangela yezifo eziningi. Ukuze wenze i-ibhalansi acid-base ziyadingeka Wellness yokuhlanza nezinqubo futhi ewusizo ukudla ukudla okunomsoco.

Ukudla pH ibhalansi

Nasi uhlu izithako ukuthi etuswayo ukukufaka ukudla noma ukudla ngokwehlukana. Lezi zihlanganisa:

• ulethisi;
• okusanhlamvu;
• ngokuphelele noma iyiphi imifino;
• izithelo ezomisiwe;
• amazambane;
• nati;
• lamanzi esiphethu;
• amanzi okuphuza Easy.

Ukuze kulesetayelekile inani alikhali emzimbeni futhi imbangela pH inkomba e-plasma evamile, odokotela abaningi belulekwa ukuba baphuze amanzi ane-alikhali: ahlanganiswe ion, it is ngokuphelele amuncwa wumzimba isungule ukulingana acid alikhali therein. Phakathi kwezinye izinto, la manzi kuqinisa amasosha omzimba, kuyasiza ukuba ukhiphe ubuthi, kubambezela inqubo yokuguga bese has imiphumela ezuzisayo on esiswini. Abelaphi luleka ukuphuza 1 ingilazi amanzi ane-alikhali ekuseni emini ngisho ukudla 2-3 izinkomishi. Ngemva enjalo isamba ngcono isimo igazi. Yilokho nje ukugeza phansi imithi amanzi ezifana kuyinto engathandeki ngoba kunciphisa ukusebenza kwe imithi ethile. Uma uphuza imithi ke phakathi kwawo yokwamukela amanzi ane-alikhali aye okungenani ibe ihora elilodwa. Lokhu amanzi ionized lingaphuzwa wekugcina, futhi ungakwazi ukuyisebenzisa zokupheka, ukupheka isobho wakhe futhi broths, esetshenziselwa itiye uthuthuva, ikhofi kanye izithelo compotes. Izinga pH emanzini ezifana ilungile.

Njengoba kujwayeleke igazi pH ngokusebenzisa amanzi ane-alikhali

Lokhu amanzi Asigcini ukuze bathuthukise impilo yabo, kodwa futhi ugcine ukubonakala ayesekhulile futhi bachuma. ukusetshenziswa nsuku zonke ngokuthelwa yilolu ketshezi kusiza umzimba sibhekane ngokuphumelelayo imfucuza esidi ngokushesha chaza kubo, njalo khona bezazila isuswa umzimba. Njengoba ekuqongeleleni nosawoti kanye acid ibe nomphumela ongemuhle abhekisele esimweni esasivamile nempilo ke ukususa lezi zitoko anikeza umuntu amandla, amandla kanye ophethe ajabule. Kancane kancane, libonisa izinto ezingadingekile emzimbeni futhi ngaleyo ndlela awuyeka kuphela lokho kuyadingeka ngempela ngoba zonke izinhlaka ukuba asebenze kahle. Njengoba insipho alikhali isetshenziswa ukuze ususe amagciwane engadingeki futhi amanzi ane-alikhali isetshenziselwe ukususa zonke okweqile kusukela umzimba. Kulesi sihloko uzofunda konke mayelana acid-base ibhalansi igazi ikakhulukazi wonke umzimba. Satshela mayelana umsebenzi igazi, indlela ukufunda pH igazi ku okucwaninga futhi ekhaya, kwezinkambiso okuqukethwe acid alikhali egazini, kanye ukuhlukahluka ezihlobene naso. Futhi, manje kutholakale kalula uhlu imikhiqizo ukwandisa ayinayo noma asidi yegazi. Ngakho, ungakwazi ukuhlela ekudleni kwakho ukuze adle olinganiselayo hhayi kuphela, kodwa ngesikhathi esifanayo wokuqhubeka ezidingekayo wegazi pH.
