Indlela Ama-hormone E-thyroid Asebenza Ngayo Emetabolism Ama-hormone e-thyroid aziwa njengenye yabalawuli ababalulekile bezinqubo ezahlukahlukene zomzimba emzimbeni womuntu. Lawa ma-hormone adlala indima ebalulekile ekulawuleni imetabolism, inqubo eqinisekisa ukuthi umzimba wakho uthola amandla owadingayo ukuze wenze imisebenzi yansuku zonke. Ukuqonda ukuthi ama-hormone e-thyroid asebenza kanjani emetabolism kungakunikeza ukuqonda okujulile… Funda kabanzi

Inqubo Yokugoba Kwegazi Nezici Eziyithintayo Ukugoba kwegazi, noma ukugoba kwegazi, kuyinqubo ebalulekile yezinto eziphilayo evimbela ukulahleka kwegazi ngokweqile lapho umthambo wegazi ulimele. Le nqubo ihilela uchungechunge lwezimpendulo eziyinkimbinkimbi nezixhumene ezibandakanya izingxenye ezahlukene zegazi namaprotheni. Lesi sihloko sizoxoxa ngenqubo yokugoba kwegazi ngokujulile nangokujulile… Funda kabanzi

Indlela Yokusebenza Engaba Khona Kumaseli Emizwa Isingeniso Amaseli emizwa, noma ama-neurons, ayisisekelo sesimiso sezinzwa futhi asebenza ukudlulisa ulwazi kuwo wonke umzimba. Enye yezindlela eziyinhloko ezenza lokhu kudluliswa kolwazi yikhono lokusebenza. Amandla okwenza isenzo ushintsho olusheshayo nolwesikhashana ku-voltage yolwelwesi lweseli lezinzwa oluvumela isignali kagesi ukuthi ihambe... Funda kabanzi

Isakhiwo Nomsebenzi Wenhliziyo: I-myocardium, noma imisipha yenhliziyo, iyisici esibalulekile sesimiso senhliziyo yomuntu. Umsebenzi wayo oyinhloko ukupompa igazi emzimbeni wonke, indima edinga ukusebenza kahle okukhulu nokukhuthazela, njengoba inhliziyo isebenza ngokungayeki empilweni yomuntu. Ukuze siqonde ubunzima bayo, ucwaningo lwesakhiwo sayo nomsebenzi wayo lubalulekile. Kulesi sihloko, sizo… Funda kabanzi

Indlela I-Alveoli Esebenza Ngayo Ekushintsheni Kwegesi Ama-Alveoli ayizakhiwo ezincane, ezifana nezikhwama emaphashini ezidlala indima ebalulekile ekushintsheni kwegesi phakathi kohlelo lokuphefumula lomuntu kanye nohlelo lokujikeleza kwegazi. Atholakala ekugcineni kwemigudu yomoya ye-bronchial, ama-alveoli yilapho umoya-mpilo ovela emoyeni ungena khona egazini, bese kuthi i-carbon dioxide evela egazini ikhishwe iye emgudwini womoya.

Ukubaluleka kwe-Asidi Yesisu Enqubweni Yokugaya I-Asidi yesisu, eyaziwa kakhulu kwezokwelapha ngokuthi i-hydrochloric acid (HCl), iyisici esibalulekile ohlelweni lokugaya ukudla komuntu. Nakuba ngokuvamile ibhekwa njengesici esibangela ubuhlungu nezinkinga ezifana nesilungulela kanye nezilonda, i-asidi yesisu idlala indima ebalulekile ekuqinisekiseni ukuthi ukudla esikudlayo kugaywa kahle.

Indima Ye-Adrenaline Empendulweni Yokulwa Noma Yokundiza Wonke umuntu, kusukela ezikhathini zasendulo kuze kube manje, ubhekene nezimo ezibangela ukucindezeleka noma izinsongo. Ezikhathini ezinjalo, umzimba unendlela ehlukile eyaziwa ngokuthi impendulo yokulwa noma ukundiza. Lokhu kuyimpendulo ehlelekile kakhulu yomzimba kanye neyengqondo, futhi yingxenye eyodwa ye… Funda kabanzi

Kungani Imisipha Ikhathala Ngesikhathi Sokuzivocavoca Uma umuntu enza umsebenzi womzimba, njengokuzivocavoca, imisipha yakhe isebenza njengenjini eyinhloko eshukumisa umzimba. Kodwa-ke, njengomshini, le misipha ingakhathala futhi idinga ukuphumula ngaphambi kokuba iphinde isebenze kahle. Isimo sokukhathala kwemisipha siyinkimbinkimbi futhi sithonywa yizici ezahlukahlukene, kusukela enkambisweni... Funda kabanzi

Ukulawulwa Komfutho Wegazi Yisistimu ye-Renin-Angiotensin: Izindlela Nemiphumela Yomtholampilo Isingeniso Ukucindezeleka kwegazi kuyisici esibalulekile sempilo esithinta inhlalakahle yethu iyonke kanye nempilo yethu. Ukulawulwa komfutho wegazi okufanele kubalulekile ekugcineni ukusebenza kwezitho ezibalulekile, ukuthuthukisa ikhwalithi yokuphila, kanye nokuvimbela izifo ezahlukahlukene zenhliziyo nemithambo yegazi. Enye yezindlela ezibalulekile zokulawula umfutho wegazi… Funda kabanzi

Isakhiwo kanye Nomsebenzi Wesistimu Yokuphefumula Yomuntu Uhlelo lokuphefumula lomuntu luyisistimu ebalulekile ephethe ukuhlinzeka nge-oxygen kuwo wonke umzimba kanye nokususa i-carbon dioxide njengomkhiqizo ongcolile. Lolu hlelo luqukethe izingxenye eziningana ezibalulekile ezisebenza ngokubambisana ukuqinisekisa ukuphefumula okuphumelelayo. Lesi sihloko sizongena ngokujulile... Funda kabanzi
