Funda mayelana nezingxenye ezisinda kakhulu zomzimba wakho

Isitho ngasinye emzimbeni womuntu sakhiwe iqembu lezicubu ezisebenza ndawonye ukuze zenze umsebenzi othile emzimbeni, njengokugaya imisoco noma ukukhiqiza izithunywa zamakhemikhali ezenza amangqamuzana obuchopho akwazi ukuxhumana. Nakuba ososayensi benemibono ehlukene ngokuthi yini ngempela ebaluleke njengesitho, inani lezitho ezicashunwe kakhulu emzimbeni womuntu zingama-78, okuhlanganisa izingxenye eziyinhloko zokusebenza ezifana nobuchopho nenhliziyo, kanye nezitho zomzimba ezincane, njengolimi.

Ngokwe-Live Science, izitho zomzimba womuntu ziza ngazo zonke izinhlobo nobukhulu ukuze zibonise inqwaba yemisebenzi ebalulekile eziyenzayo. Kodwa iyiphi ingxenye yomzimba enesisindo esikhulu? Ungase umangale uma wazi impendulo yalo mbuzo, kanje:

isikhumba

Isikhumba sithwele umqhele wesitho esinzima kunazo zonke emzimbeni womuntu, kodwa kukhona ukungqubuzana kokuthi sinesisindo esingakanani ngempela. Eminye imithombo ibonisa ukuthi abantu abadala bathwala isilinganiso se-3.6 kg yesikhumba, kanti eminye imithombo ithi isikhumba sakha cishe i-16% yesisindo somzimba sabantu abadala, kulokhu uma umuntu enesisindo esingama-77 kg, isibonelo, isikhumba sakhe sizoba nesisindo esingaba ngu-12.3 kg. XNUMX kg.

Ngokombiko we-1949 kuyi-Journal of Investigative Dermatology, isilinganiso esiphezulu sibala i-pannus adipose, ungqimba lwezicubu ezinamafutha ezitholakala phakathi kwezingqimba ezingaphezulu zesikhumba kanye nezicubu ezingaphansi, njengengxenye yesikhumba, kuyilapho lolu ngqimba lwezicubu lubalwa. ngokwehlukana ezilinganisweni zesisindo esiphansi.

Ababhali balo mbiko baphikisana nokufakwa kwe-pannus adipose futhi ngaleyo ndlela baphetha ngokuthi isikhumba sakha cishe u-6% wesisindo somuntu omdala. Kodwa umbhalo wakamuva wereferensi yezokwelapha, i-Primary Care Notebook, uthi izicubu ze-adipose ziyingxenye yesikhumba sesithathu nesingaphakathi, i-hypodermis, okubonisa ukuthi kufanele ibalwe.

Ithambo lethanga

Uhlaka lwamathambo luwuhlelo lwemvelo, noma iqoqo lezitho ezihlangene zenza imisebenzi ethile yomzimba. Uhlaka lwamathambo lungolunye lwezinhlelo zesitho ezinkulu kakhulu emzimbeni womuntu, futhi lungaba nesisindo esicishe sibe amaphesenti ayi-15 esisindo somzimba womuntu omdala, ngokusho kokubuyekezwa kwango-2019 okushicilelwe ku-International Journal of Biological Sciences.

Uhlaka lwamathambo abantu abadala ngokuvamile luqukethe amathambo angu-206, nakuba abanye abantu bengase babe nezimbambo ezengeziwe noma ama-vertebrae. I-femur, ephakathi kwedolo ne-hip, inzima kunazo zonke. Ngokwesilinganiso, i-femur inesisindo esingamagremu angu-380, kodwa isisindo sayo esiqondile siyahlukahluka kuye ngeminyaka, ubulili kanye nesimo sezempilo.

isibindi

Ngokusho kwe-American Liver Foundation, isibindi sinesisindo esingamakhilogremu angu-1.4 kuya ku-1.6 futhi siyisitho sesibili esinzima kakhulu emzimbeni womuntu. Isibindi siyisitho esimise okwekhoni esitholakala ngenhla kwesisu nangaphansi kwe-diaphragm, okuyisisipha esimise okwedome ngaphansi kwamaphaphu. Isibindi sisiza ukudiliza ubuthi futhi sigaye ukudla, phakathi kweminye imisebenzi ebalulekile. Ngokwe-Johns Hopkins Medicine, isibindi sibamba cishe ingxenye yelitha legazi ngaso sonke isikhathi, okungamaphesenti angaba ngu-13 egazi elitholakala emzimbeni.

ubuchopho

Kusukela ekucabangeni kuya ekulawuleni ukunyakaza, ubuchopho bomuntu benza inqwaba yemisebenzi ebalulekile emzimbeni, futhi isisindo sabo sibonisa ukubaluleka kwabo. Ngokombiko wephephabhuku i-PNAS, ubuchopho bubalelwa ku-2% wesilinganiso sesisindo somzimba womuntu omdala.

Isisindo sobuchopho sincike eminyakeni yobudala kanye nobulili bomuntu. Lapho eneminyaka engu-1.4 ubudala, ubuchopho bomuntu buba nesisindo esingu-65 kg. Lapho eneminyaka engu-1.3, yehla ibe ngu-10 kg. Ngokwe-Encyclopedia of the Human Brain yezemfundo, ubuchopho besifazane buba nesisindo esingaphansi ngamaphesenti ayishumi kunobuchopho bowesilisa, kodwa ngokukamagazini i-Intelligence, lapho kucatshangelwa isisindo somzimba wonke, ubuchopho bamadoda buvame ukuba ngamagremu ayikhulu kuphela.

iphaphu

Amaphaphu aphakathi kwezingxenye ezisinda kakhulu zomzimba womuntu. Iphaphu langakwesokudla livamise ukuba nesisindo esingaba ngu-0.6 kg, kanti iphaphu lesokunxele lincane kancane futhi linesisindo esingaba ngu-0.56 kg. Amaphaphu amaduna amadala nawo asindayo kunalawo ezinsikazi.

Kuyathakazelisa ukuthi amaphaphu anesisindo esingamagremu angu-40 lapho ezalwa. Amaphaphu akhula ngokugcwele lapho i-alveoli yakheka eneminyaka emibili, lapho amaphaphu enesisindo esingamagremu angu-170.

inhliziyo

Inhliziyo yomuntu iphakathi nendawo yesimiso sokujikeleza kwegazi futhi impompa igazi ngokungakhathali emzimbeni, ithumela umoya-mpilo nezakhi ezicutshini. Imicu yemisipha esindayo eqhuba ukushaya kwenhliziyo ilandisa ingxenye enkulu yesisindo sayo. Inhliziyo inesisindo esingamagremu angu-280 kuya ku-340 kwabesilisa abadala kanye namagremu angaba ngu-230 kuya ku-280 kwabesifazane abadala.

izinso

Izinso zikhipha ubuthi nokungcola komzimba. Lo msebenzi obalulekile wenziwa ama-nephron, okuyizakhiwo ezincane ezisebenza njengezihlungi phakathi komjikelezo wegazi nesinye. Inso ngayinye inezigidi zama-nephron, okwenza lesi sitho esibalulekile sibe esinye sesisindo somzimba. Inesisindo esiphakathi kuka-125 kuya ku-170 amagremu kwabesilisa abadala kanye ne-115 kuya ku-155 amagremu kwabesifazane abadala.

ubende

Njengoba iseduze kwama-pancreas, i-spleen ikhipha amangqamuzana egazi abomvu amadala nalimele egazini, ilawula amazinga ajikelezayo amangqamuzana amhlophe egazi, futhi ikhiqize amasosha omzimba nama-molecule omzimba asiza ukulwa nezifo. Ubende lunesisindo esingamagremu ayi-150 kubantu abadala, kepha ngokusho kokubuyekezwa kwesayensi kwango-2019 okushicilelwe ephephabhukwini elithi Surgery, isisindo siyahlukahluka kumuntu nomuntu.

amanyikwe

Amanyikwe alawula amazinga kashukela egazini futhi akhiphe ama-enzyme asiza amathumbu amunce imisoco ekudleni okugayiwe. Kanye ne-spleen, i-pancreas iyisitho esinzima sokugaya ukudla. Amanyikwe ngokuvamile anesisindo esingamagremu angama-60 kuye kwayi-100 kumuntu omdala. Kungaba nesisindo esingafika ku-180 amagremu kwabanye abantu.

Indlala yegilo

Indlala yegilo itholakala entanyeni futhi idlala indima enkulu ekulawuleni ukusetshenziswa kwamandla emzimbeni. Isisindo sabo siyahlukahluka phakathi kwabantu, kodwa ngokuvamile banesisindo esingamagremu angu-30. Indlala yegilo ingase ibe nzima ngesikhathi sokuya esikhathini nokukhulelwa. I-Hyperthyroidism, isimo sezokwelapha esibangela ukuthi indlala yegilo ikhiqize amahomoni amaningi kunalokho okudingwa umzimba, ingabangela ukuba ikhule futhi ikhule ngosayizi.

i-prostate gland

Naphezu kobukhulu bayo obuncane, obungafaniswa nobukhulu be-walnut, i-prostate ingenye yezitho ezisinda kakhulu emzimbeni womuntu. Isilinganiso sesisindo se-prostate esikhulile singamagremu angu-25, kodwa isisindo sayo singahluka kumuntu nomuntu. Ngokusho kweNyuvesi yase-Utah, i-prostate ekhulisiwe ingakhula ibe ngaphezu kokuphindwe kathathu kobukhulu obujwayelekile nesisindo sibe cishe amagremu angu-80.
