Umsebenzi We-Nucleus Yeseli Nendlela Elawula Ngayo Umsebenzi Weseli I-nucleus ingenye yama-organelle abaluleke kakhulu kumaseli e-eukaryotic—lawo atholakala ezilwaneni, ezitshalweni, ezikhunta, kanye nakuma-protist. I-nucleus ivame ukubizwa ngokuthi "isikhungo sokulawula" seseli ngoba igcina izinto zofuzo (i-DNA) ezilawula cishe zonke izinqubo zokuphila kweseli. Kodwa-ke, indima ye-nucleus ayigcini...

Izinzuzo Zokuzivocavoca Kwesimiso Senhliziyo Nemithambo Yegazi Uhlelo lwenhliziyo nemithambo yegazi—oluhlanganisa inhliziyo, imithambo yegazi kanye negazi—ludlala indima ebalulekile ekugcineni zonke izitho zomzimba zisebenza. Kungalolu hlelo lapho umoya-mpilo nezakhamzimba zisatshalaliswa khona ezicutshini, kuyilapho imikhiqizo engcolile ye-metabolic efana ne-carbon dioxide isuswa ukuze ikhishwe. Ngenxa yendima yayo ebalulekile, impilo yenhliziyo nemithambo yegazi ingenye yezinkomba eziyinhloko zokufaneleka komzimba kanye… Funda kabanzi
Isakhiwo Nokusebenza Kwamaseli Egazi Abomvu Amaseli egazi abomvu, noma ama-erythrocyte, angenye yezingxenye eziyinhloko zegazi ohlelweni lokujikeleza kwegazi lwabantu kanye nezinye izilwane ezinomgogodla. Lawa maseli adlala indima ebalulekile ekuthuthweni komoya-mpilo usuka emaphashini uye kuzo zonke izicubu zomzimba kanye nokuthwala i-carbon dioxide, umkhiqizo ophumayo we-metabolic, usuka ezicutshini zomzimba uye emaphashini ukuze ukhishwe. Ukuqonda isakhiwo kanye… Funda kabanzi
Ukubaluleka kwe-Collagen Esikhumbeni Esinempilo I-Collagen ingenye yamaprotheni amaningi emzimbeni womuntu, enikela cishe u-30% weprotheyini yomzimba wonke kanye no-70% weprotheyini yesikhumba. Abaningi bayaqaphela i-collagen njengengxenye ebalulekile emikhiqizweni yokunakekelwa kwesikhumba, imikhiqizo yokufaneleka, kanye nezithasiselo zezempilo. Kodwa-ke, bambalwa abakuqonda ngempela ukubaluleka kwayo kanye nemisebenzi yayo ehlukahlukene… Funda kabanzi
Izinzuzo Zokuzivocavoca Nge-Aerobics Zesistimu Yokuphefumula I-Aerobics uhlobo lokuzivocavoca umzimba osekuyisikhathi eside luqashelwa njengendlela ephumelelayo yokuthuthukisa impilo iyonke. Ekuvivinyweni kwe-aerobic, abantu benza uchungechunge lweminyakazo evame ukuhilela isigqi esisheshayo nesiphindaphindayo, njengokugijima, ukugibela ibhayisikili, ukubhukuda, noma ukudansa. Lo msebenzi udinga ukutholakala komoya-mpilo omningi ukuze kulondolozwe ukuqina… Funda kabanzi
Imiphumela Yokuphelelwa Amanzi Emsebenzini Wezitho Ukuphelelwa amanzi emzimbeni yisimo lapho umzimba ulahlekelwa khona uketshezi oluningi kunalolo oluthathayo, okuwushiya ungenamanzi anele nezinye izinto eziwuketshezi ukuze usebenze ngendlela evamile. Nakuba kungase kuzwakale kulula, ukuphelelwa amanzi emzimbeni kungaba nomthelela omkhulu emzimbeni womuntu futhi kuphazamise imisebenzi ehlukahlukene yezitho. Abantu abaningi bangase bangakunaki ukubaluleka kokulondoloza ibhalansi… Funda kabanzi
Indlela Ubuchopho Obuchaza Ngayo Ubuhlungu Ubuhlungu buyinto evamile wonke umuntu azoyizwa ngesikhathi esithile empilweni yakhe. Uma usika umunwe wakho, uthola ukushisa okubangelwa ukushisa epanini elishisayo, noma uzwa ubuhlungu bezinyo, umzimba wakho uphendula ngokuthumela izimpawu zobuhlungu. Kodwa-ke, indlela ubuchopho obuchaza ngayo lobo buhlungu inqubo eyinkimbinkimbi kakhulu… Funda kabanzi
Izindlela Zokwelapha Amanxeba kanye Nendima Yamaseli Amhlophe Egazi Inxeba liwumonakalo ezicutshini zomzimba, ngokuvamile obangelwa yinto ebukhali, ukusha, ukutheleleka, noma okunye ukulimala ngokomzimba. Uma kwenzeka inxeba, umzimba usebenzisa indlela yokwelapha eyinkimbinkimbi kakhulu futhi elawulwayo ukulungisa izicubu ezonakele. Ingxenye eyodwa ebalulekile kule nqubo amaseli amhlophe egazi… Funda kabanzi
Ukubaluleka Kwe-Calcium Empilweni Yamathambo I-Calcium iyiminerali ebalulekile edlala indima ebalulekile emzimbeni womuntu. Omunye wemisebenzi yayo eyinhloko ukunikeza amandla nesakhiwo emathanjeni. Ngaphezu kwama-99% e-calcium emzimbeni womuntu agcinwa emathanjeni nasemazinyweni, okwenza kube yingxenye ebalulekile yokugcina uhlelo lwamathambo olunempilo. Lesi sihloko sizohlola ngokujulile ukuthi... Funda kabanzi
Umehluko Phakathi Kwe-Plasma Ne-Blood Serum Igazi liyingxenye ebalulekile yomzimba womuntu, lithutha umoya-mpilo, izakhamzimba, ama-hormone, nezinye izinto kuzo zonke izitho nezicubu. Igazi lakhiwe yizinto ezahlukahlukene ezivumela izinhlelo zomzimba ukuthi zisebenze kahle. Kunezingxenye ezimbili eziyinhloko zegazi eziwuketshezi ezivame ukuxoxwa ngazo kwezokwelapha nasocwaningweni… Funda kabanzi
