Kokubili iplanethi nezidalwa eziphilayo zakhiwe ngamanzi amaningi. Izilwandle zimelela cishe amaphesenti angama-97 obuso bomhlaba. Ukubaluleka Kwamanzi Ezidalwa Eziphilayo ukuthi lo mthombo ubalulekile ekwenzeni izinqubo zebhayoloji. Amanzi kubantu amelela cishe izingxenye ezimbili kwezintathu zesisindo somzimba. Ngiyakumema ukuthi ufunde kabanzi mayelana Nokubaluleka Kwamanzi Ezidalwa Eziphilayo.
Ukubaluleka Kwamanzi Ezidalwa Eziphilayo
Amanzi atholakala ezithweni ezahlukene zabantu, njengobuchopho, inhliziyo, isibindi, izinso, kanye nezinye izitho nezicubu. Imele isakhi esiyinhloko sokwenza ukugaya kanye nokumuncwa nokuqedwa kwezinsalela ze-metabolic ezingakwazi ukufakwa. Iyingxenye yesakhiwo sesimiso sokujikeleza kwegazi futhi ngegazi ithwala imisoco namaminerali kuwo wonke umzimba. Ukusebenzisa inani elifanele lamanzi kusiza ukufaka amanzi emzimbeni futhi kulawule izinga lokushisa le-somatic, liwavumele aphume ngomjuluko ngomjuluko womzimba.
Imisebenzi yamanzi emzimbeni
Amanzi abalulekile ezidalwa eziphilayo, enza imisebenzi emine enjengale: ukulawula izinga lokushisa lomzimba, ukuthwala imisoco nomoya-mpilo, ukusiza ukuqeda ubuthi, ukugcoba amalunga, ukuqeda ukoma nezinye izinto eziphilayo okufanele zazi ukuze zikwazi ukumunca amanzi anele adingwa ngumzimba ukuze ziwafanele. ukusebenza.
Ilawula ukushisa komzimba
Amanzi ahilelekile ohlelweni lokwehlisa izinga lokushisa lomzimba lapho izinga lokushisa lendawo yangaphandle likhuphuka. Le nqubo yokukhulula ukushisa yenziwa ukujuluka kwamanzi emzimbeni. Phakathi nomsebenzi othile wezemidlalo noma usuku olunamazinga okushisa aphezulu, umuntu angakhulula ukushisa, lapho elahlekelwa kufika ku-1,5 amalitha omjuluko ngehora. Indlela yokuvikela abantu inqubo ye-metabolic eyenzeka lapho izinga lokushisa lendawo liphezulu kakhulu, nokuthi igazi lishiya ama-capillary angaphezulu kakhulu esikhumba ukuze ligcine isikhumba sipholile.
Ithwala imisoco nomoya-mpilo kuwo wonke umzimba
Amanzi ahilelekile ezinqubweni zamakhemikhali ezinto eziphilayo zokugaya ukudla, okunomthelela ekuwohlokeni kokudla. Ngokunjalo, amanzi aneqhaza ohlelweni lokujikeleza kwegazi, ngokuhambisa izakhamzimba (amaminerali, ama-antioxidants, amavithamini kanye neglucose) kanye nomoya-mpilo kumaseli ahlukene omzimba. I-plasma yegazi yenziwe ngamanzi angama-91%.
iqeda ubuthi emzimbeni
Njengoba nje amanzi akha igazi ehambisa izakhi nomoya-mpilo, isimiso sokujikeleza kwegazi simunca izinto ezilahlwa amangqamuzana, ukuze ziphume ngomchamo nangendle nangezithukuthuku. Ngaphezu kwalokho, amanzi asiza ukusebenza kahle kwezinso, okuyizitho zomzimba ezihluza ubuthi.
Isiza ukugcoba amalunga
Amanzi abalulekile ezidalwa eziphilayo, ngoba ayasiza nasekugcobiseni amalunga ukuze asebenze kalula. Kunconywa ukuthi udle amanzi anele ukuze ugweme ukubonakala kokulimala kanye nesifo samathambo. Ngokunjalo amanzi ayasiza ukuvikela amathambo ngoba asebenza njengesivikeli samathambo nomgogodla ekuhlukumezekeni, kanjalo nezinye izitho zomzimba wezidalwa eziphilayo njengobuchopho, umnkantsha namehlo.
Ibhalansi yamanzi angenayo naphumayo
Izinto eziphilayo zihlale zifaka futhi ziqeda amanzi emzimbeni, omunye wemisebenzi ebalulekile yomzimba ukuqinisekisa ukuthi le nqubo ihlala ilinganisela. Ngenxa yokuthi umzimba awunaso isitho sokugcina amanzi, kubalulekile ukuthi uhlale ungenisa amanzi anele ukuze ubuyisele amanani amanzi alahlekile. Kulula ngomzimba womuntu ukuba ungadli izinsuku ezimbalwa, kodwa lokhu kuzoba isikhathi esifushane kakhulu uma ungawadli amanzi.
Izidalwa eziphilayo ziphakanyiswa ukuthi zifake phakathi kwamalitha angu-1,5 kuya kwangu-3 amanzi ngosuku. Amaphesenti angama-50 ala manzi angahlanganiswa neziphuzo nokudla okuqinile. Ngokudla izithelo neminye imifino, eyakhiwe ngamanzi angama-95%, amaqanda, angamanzi angama-90%, nenyama ebomvu nenhlanzi, ezakhiwe ngamanzi angama-60 kuye kwangama-70%.
qeda ukoma
I-hypothalamus, okungenye yezifunda zobuchopho, iphethe ukukhombisa ukuthi ukugxila kwe-plasma yegazi kuyanda, lokhu kusho ukuthi umzimba unezinga elincane lamanzi futhi uphelelwa amanzi. Kulapho ubuchopho bukhipha uchungechunge lwezimpawu noma izisusa ezibangela ukoma. Futhi, umlomo owomile ngenxa yokuntuleka kwamathe kuyinkomba yokuthi kufanele uphuze amanzi. Umuntu angahamba izinsuku ezinhlanu engawaphuzi amanzi.
Izakhiwo zamanzi
Amanzi anempahla eyenza abaluleke empilweni, ngemisebenzi yayo ehlukene kukhemistri, i-biochemistry kanye ne-biology yezidalwa eziphilayo, kanye nezindawo zayo ezihlukahlukene. Izakhiwo zayo ezingokomzimba zihlobene nezakhiwo zayo ezishisayo kanye nezakhi zayo zamakhemikhali zihlobene nendlela esabela ngayo kwezinye izinto.
Amanzi ayincibilikisi
Enye yezimpawu zamanzi ukuziphatha kwawo njengesincibilikisi. Lokhu kusho ukuthi izinto eziningi nezinto eziqinile zingancibilika emanzini ukwenza izixazululo. Ngamanzi ama-molecule amaningi abalulekile nezinye izinhlayiya zithuthwa kuwo wonke umzimba. Lezi zinto zingaba umsoco kanye nemikhiqizo engcolile evela ezinqubweni zomzimba zomzimba.
ukunyakaza kwama-molecule amanzi
Amanzi ezinto eziphilayo avumela ukuhlanganisa ezinye izinhlayiya nama-molecule njengama-ion, athuthwa ngegazi ezicubu kanye nolwelwesi. Lokhu kungazuzwa ngezixazululo. Isibonelo, ukuthuthwa komoya-mpilo ngegazi kulo lonke uhlelo lwe-vascular.
amanzi ekuphenduleni kwamakhemikhali
Ekuphenduleni kwamakhemikhali, ama-reagents ahlobene namanye noma ngenhlanganisela noma into esebenza njenge-catalyst. Izixazululo ngokuvamile zinhle ekuphenduleni kokusabela ngoba izincibilikisi, njengamanzi, zimboza izincibilikisi ezinamandla okuziphatha njengezici ezivuselelayo uma kunethuba lokusabelana. Lokhu kwenzeka lapho izinto ezimbili noma ngaphezulu ezisabelayo zisesixazululweni esifanayo futhi zishayisana futhi zidale ukusabela.
Ukusabela phakathi kwezinto ezisabelayo kuncike ezintweni ezimbalwa, njengokuhlangana kwezinyibilikisiwe, izinga lokushisa lesixazululo, nokuba khona kwe-catalyst yokusabela.
Emzimbeni, ama-molecule amanzi abamba iqhaza ekucubunguleni ama-carbohydrate namaprotheni ngesikhathi sokugaya. Kulezi zimo, ama-molecule amanzi abamba iqhaza ekuphenduleni kokubola lapho amanye ama-molecule ahlukaniswa abe izingxenye ezincane. Ngokufanayo, amanzi akhiqizwa ngesikhathi sokusabela kwezinye izinhlanganisela eziphilayo ezihlotshaniswa nokwenza ama-molecule amakhulu anezakhiwo eziyinkimbinkimbi. Ukuthi umzimba uyakudinga ukwenza imisebenzi ethile efana nokwakha ama-nucleic acid namahomoni.
Uma uthanda ukwazi imvelo emangalisayo, ngikumema ukuthi ufunde okwengeziwe ngayo nokuthi kungani uyinakekela. Funda lokhu okuthunyelwe:
