Umphumela Wokudla Okunoshukela Ophakeme Ekuphikisweni Kwe-Insulin Isingeniso Emashumini eminyaka amuva nje, ukusabalala kwesifo sikashukela sohlobo 2 kukhuphuke kakhulu emhlabeni jikelele. Esinye sezici eziyinhloko ezibangela ukwanda kwamacala esifo sikashukela ukudla okungenampilo, ikakhulukazi ukudla okunoshukela omningi. Ukusetshenziswa ngokweqile koshukela akuthinti nje isisindo somzimba kodwa futhi... Funda kabanzi
Indima Ye-Mitochondria Ekukhiqizweni Kwamandla Eselula I-Mitochondria ivame ukubizwa ngokuthi "izindawo zamandla" zamaseli, futhi indima yayo ekukhiqizweni kwamandla ayinakweqiswa. Lezi zakhiwo ziyizingxenye ezibalulekile zamaseli e-eukaryotic, okuqinisekisa ukuthi izinto eziphilayo zinokunikezwa kwamandla okwanele kwemisebenzi eyahlukahlukene yezinto eziphilayo. Lesi sihloko sizohlola ngokujulile ukuthi i-mitochondria inikela kanjani ku… Funda kabanzi
Umsebenzi Wama-Platelet Ekuvimbeni Kwegazi Ama-Platelet, avame ukubizwa ngokuthi 'ama-platelet' ngokwezokwelapha, ayisici esibalulekile segazi esihilelekile enqubweni yokuvimbezela igazi (ukujiya). Nakuba emancane kunamaseli egazi abomvu namhlophe, ama-platelet adlala indima ebalulekile ekuvikeleni umzimba ekulahlekelweni yigazi ngokweqile ngesikhathi sokulimala. Kulesi sihloko, … Funda kabanzi
Kungani Uhlelo Lwe-Lymphatic Lubalulekile Esistimu Yokuzivikela Emzimbeni Isingeniso Uhlelo lwe-lymphatic luyinethiwekhi eyinkimbinkimbi yama-lymph node, imithambo ye-lymph, kanye noketshezi lwe-lymph (i-spleen), okusebenza ndawonye ukugcina ibhalansi yoketshezi lomzimba, ukumunca amafutha emathunjini, futhi okubaluleke kakhulu, kudlala indima enkulu ohlelweni lokuzivikela komzimba. Ngaphandle kohlelo lwe-lymphatic olusebenza kahle, umzimba uzo… Funda kabanzi
Ukusebenzisana Phakathi Kwezinhlelo Ze-Endocrine Nezinzwa Isingeniso Umzimba womuntu ungumshini wezinto eziphilayo oyinkimbinkimbi kakhulu futhi ohlanganisiwe, lapho izinhlelo ezahlukene zisebenza ndawonye ukugcina i-homeostasis, noma ibhalansi yangaphakathi. Izinhlelo ezimbili ezibaluleke kakhulu nezisebenzisanayo yizinhlelo ze-endocrine kanye nezinzwa. Zombili zidlala indima ebalulekile ekulawuleni imisebenzi yomzimba, kusukela... Funda kabanzi
Inqubo Yokumuncwa Kwezakhamzimba Yithumbu Elincane Ukumuncwa kwezakhamzimba emzimbeni womuntu kungenye yezici ezibaluleke kakhulu zesimiso sokugaya ukudla. Ngemva kokuba ukudla kugaywe kube ama-molecule amancane, umsebenzi oyinhloko wesimiso sokugaya ukudla ukumuncwa kwezakhamzimba ukuze zisetshenziswe amaseli nezicubu zomzimba ezahlukahlukene. Amathumbu amancane adlala indima ebalulekile kule nqubo, njengoba iningi… Funda kabanzi
Ukulawulwa Kokushisa Komzimba yi-Hypothalamus Ukushisa komzimba womuntu kuyipharamitha ebalulekile yomzimba, ekhonza ukugcina ibhalansi ye-metabolic kanye nempilo iyonke. Ingxenye eyodwa ebalulekile yesistimu yokulawulwa kokushisa komzimba yi-hypothalamus, ingxenye yobuchopho edlala indima emisebenzini ehlukahlukene ye-homeostatic, okuhlanganisa nokulawula ukushisa komzimba. Lesi sihloko sizohlola ukuthi i-hypothalamus isebenza kanjani ekulawulweni… Funda kabanzi
Izindlela Zokuzivumelanisa Nezimo Ngesikhathi Sokuzivocavoca Ukuzivocavoca umzimba kuwumsebenzi obalulekile empilweni yomzimba neyengqondo. Ngokuzivivinya umzimba, imizimba yethu idlula ochungechungeni lwezimo ezisenza sikwazi ukusebenza kahle nangendlela ephumelelayo. Lokhu kuzivumelanisa nezimo kuhlanganisa izici ezahlukahlukene zezinhlelo zenhliziyo, zokuphefumula, zemisipha, kanye nezezinzwa. Ukuqonda lezi zindlela zokuzivumelanisa nezimo kubalulekile ekuklameni… Funda kabanzi
Umsebenzi Wamaseli E-Pancreatic Beta Ekukhiqizweni Kwe-Insulin Isingeniso I-pancreas iyisitho esisebenza ngemisebenzi eminingi esitholakala ngemuva kwesisu naseduze nengxenye engenhla yamathumbu amancane. I-pancreas inezindima ezimbili eziyinhloko: umsebenzi we-exocrine wokusiza ukugaya kanye nomsebenzi we-endocrine wokulawula amazinga kashukela egazini. Ngaphakathi kwe-pancreas kuneziqoqo zamaseli akhethekile aziwa ngokuthi iziqhingi zaseLangerhans. Kusukela … Funda kabanzi
Umehluko Phakathi Kwemithambo Nemithambo Uhlelo lokujikeleza kwegazi lomuntu luyinethiwekhi eyinkimbinkimbi equkethe inhliziyo, imithambo, imithambo kanye nama-capillary, asebenzisana ukuze ajikeleze igazi emzimbeni wonke. Imithambo nemithambo yizinhlobo ezimbili eziyinhloko zemithambo yegazi ezidlala indima ebalulekile kulesi simiso. Nakuba zombili zisebenza ukuthutha igazi, zine… Funda kabanzi
