Amabali amangalisayo ngolusu lwethu (Ulusu Lomntu): Masifunde ngokulula!

Ngaba wakha wazijonga esipilini waza wacinga, 'Luhlobo luni lolusu? Kutheni lubaluleke kangaka kuthi?'? Mhlawumbi awuzange ube nexesha lokucinga ngalo. Kodwa, olu 'lusu' esinalo emizimbeni yethu luyinto emangalisayo ngokwenene. Namhlanje, masithethe ngolusu lwethu nezinto ezenzeka kulo, ngokungathi sithetha nomhlobo.

Ngoko ke, yintoni le 'sikhumba'?

Ngamafutshane, ulusu lolona lungu likhulu emzimbeni wethu. Ewe, ukuvile kakuhle oko, elona lungu likhulu! Cinga nje, umzimba wethu wonke ugqunywe lolu lusu. Kukho izigidi zeeseli ezincinci kwi-intshi nganye yolusu lwakho. Ayipheleli apho, kodwa ngaphakathi kolu lusu kukho amadlala okubila, amadlala avelisa ioyile, iziphelo zemithambo-luvo (njengee-antennae ezincinci ezithatha iimvakalelo), kunye nemithambo yegazi emininzi. Zonke ezi zinto zisebenza kunye ukwenza ulusu lusebenze.

Ngoko ke, zeziphi iingenelo esinazo olu sikhumba kuthi?

Ulusu lwethu aluyonto nje yokwambathisa imizimba yethu. Lusinika iinkonzo ezininzi. Makhe sijonge ukuba ziintoni.

• Ikhusela amalungu abalulekileyo emzimbeni: Cinga nje, onke amalungu ethu abalulekileyo njengentliziyo, imiphunga, nezintso angaphakathi emzimbeni. Ulusu lufana nesigqubuthelo sokukhusela ezi zinto. Yiyo loo nto nokuba kukho umkrwelo okanye inxeba elincinci alizitshabalalisi ngokuthe ngqo izitho zangaphakathi.
• Isebenza njengekhaka: Zingaphi iikhemikhali eziyingozi ezikwindawo esingqongileyo? Ngenxa yokuba sinesikhumba, ezi zinto azingeni lula emzimbeni. Zifana nesambatho esikhuselayo esiqinileyo emizimbeni yethu. Yiyo loo nto singaguli rhoqo.
• Ikhusela ekwenzakaleni: Xa sibaleka, sidlala, siwa, okanye singqubana nento ethile, ulusu lunceda ekukhuseleni izicwili ezibuthathaka ngaphakathi ekonakalisweni kakhulu. Ifana nomatrasi obamba ukothuka .
• Ilawula ubushushu bomzimba: Xa siziva sishushu, ukubila kuveliswa ziindlala zokubila eluswini. Njengoko ukubila kuphuma, umzimba uyaphola. Kwakhona, ngeentsuku ezibandayo, ulusu lusinceda sihlale sifudumele ngokunciphisa ukulahleka kobushushu bomzimba. Ayimangalisi loo nto?
• Ulawulo lwaManzi: Ulusu luthintela amanzi angaphakathi emzimbeni wethu ukuba angatshi. Ngaphandle koko, sinokuphelelwa ngamanzi ngokukhawuleza.

• Inika iimvakalelo: Siva ubushushu, ukubanda, intlungu yento esihlabayo, ukuchukumisa okuthambileyo komntu osichukumisayo... Konke oku kuviwa ziziphelo zemithambo-luvo ezikhethekileyo eluswini. Ezi zifana neenzwa ezincinci ezithumela ulwazi engqondweni. Kungoko ke sinokuphepha ingozi.

Ngoko ke, lenziwe njani le sikhumba? Zithini iileya zesikhumba?

Kulungile, ngoku makhe sijonge indlela olu sikhumba lumangalisayo olwenziwe ngayo. Kukho iileya ezintathu zesikhumba. Zifana nekhekhe elenziwe ngeeleya.

1. Umaleko ophezulu: `(Epidermis)`

2. Umaleko ophakathi: `(I-Dermis)` (Ulusu)

3.Umaleko ongezantsi: `(Izicubu ezingaphantsi kolusu)`

Ezi layers zintathu zisebenza kunye njengeqela ukwenza wonke umsebenzi esiwukhankanyileyo ngaphambili. Makhe sithethe ngezi layers nganye ngokweenkcukacha ezithe vetshe, kulungile?

I-Epidermis - umaleko okhuselayo wolusu esiwubonayo

I-`(Epidermis)` yinxalenye yolusu enokubonwa nguwe, mna, kunye nathi sonke. Le yingqimba ephezulu, ekhuselayo yolusu. Ifana nodonga olungaphandle lwenqaba. Incinci kakhulu kwezinye iindawo, njengeenkophe zethu, umzekelo. Kodwa, kwelinye icala, kwiindawo ezifuna ukhuseleko olungakumbi, njengeentende zethu kunye neenyawo zethu, le `(Epidermis)` ityebile.

Kuyamangalisa ukucinga ngendlela ulusu lwethu olutshintsha ngayo ukusuka kwenye indawo ukuya kwenye ngokuxhomekeke kwiimfuno zalo!

Enye into ekhethekileyo ngale `(Epidermis)` kukuba iqhubeka nokuvelisa iiseli ezintsha. Njengoko iiseli ezindala zisifa kwaye ziwa, iiseli ezintsha ziyavela kumaleko osezantsi ukuze zithathe indawo yazo. Le nkqubo iyonke, oko kukuthi, ithatha malunga neentsuku ezingama-28, okanye malunga nenyanga, ukuba iseli entsha ikhule, inyuke iye phezulu, kwaye iwele. Ngoko ke uyazi, ufumana ulusu olutsha phantse inyanga nenyanga!

Kukho iintlobo ezintathu eziphambili zeeseli kwi-epidermis, nganye kuzo inomsebenzi othile:

• `IiMelanocytes` - Ezo zinika umbala wolusu: Ezi seli zivelisa umbala ` (iMelanin) ` (iMelanin). Ulusu lwethu neenwele zethu zifumana umbala wazo ngenxa yale ` (iMelanin) . Abanye abantu banesikhumba esimnyama, abanye banesikhumba esikhanyayo, kwaye abanye banesikhumba esimhlophe. Isizathu soko bubungakanani be` (iMelanin) . Abo bane` (iMelanin) ` engaphezulu banesikhumba esimnyama, kwaye abo banesikhumba esincinci banesikhumba esikhanyayo. Xa siphuma elangeni, xa sichatshazelwa lilanga, ezi seli ` (iMelanocytes) ` ziyakhuthazwa kwaye zivelise okungakumbi ` (iMelanin) . Yiyo loo nto xa siphuma elangeni, ulusu lwethu luba mnyama kancinci, okanye abanye abantu baba namabala. Oku kuyinto eyenziwa lusu ukuzikhusela kwimitha yelanga eyingozi.
• IiKeratinocytes - Amandla nokhuselo lolusu: Ezi seli zivelisa uhlobo oluthile lweproteni ebizwa ngokuba yiKeratin . Iinwele zethu kunye nezinzipho zenziwe ngale proteni inye . Yile proteni enika ulusu amandla nokuqina, kwaye isebenza njengekhaka lokukhusela ulusu kwiintsholongwane zangaphandle kunye nokwenzakala okuncinci.
• Iiseli zeLangerhans - Amajoni omzimba okuzikhusela eluswini: Ezi seli ziyinxalenye yenkqubo yomzimba wethu yokuzikhusela. Njengamajoni amancinci, zinceda ekuboneni nasekulweni neentsholongwane ezizama ukungena emzimbeni ngesikhumba.

I-Dermis - Isikhungo esixakekileyo sesikhumba

Ngaphantsi kwe-epidermis, umaleko ophakathi wolusu, kukho i- dermis . Le dermis ityebile kune-epidermis. Kulapho uninzi lomsebenzi obalulekileyo wolusu lwenzeka khona. Kufana nesixeko esixakekileyo.

Le `(Dermis)` yenziwe kakhulu ziintlobo ezimbini zeefayibha:

• ` ( I-Collagen): Yile nto inika ulusu amandla nokuqina. Oku kubaluleke kakhulu ekugcineni ulusu lubonakala lulutsha.
• ` (Elastin) ` (Elastin): Oku kunika ulusu ukuguquguquka. Oko kuthetha ukuba xa ulusu lutsalwa kwaye lukhululwa, lubuyela kwimo yalo yokuqala, kwaye yiloo nto ` (Elastin) ` enceda ngayo. Ifana nebhendi yerabha.

Njengoko sikhula, ukuveliswa kwe- ``Collagen`` kunye ne-`` Elastin``` kuyehla. Yiyo loo nto ulusu luqala ukushwabana nokuwa njengoko sikhula.

Ayizizo ezi fiber kuphela, kukho nezinye izinto ezininzi ezibaluleke kakhulu ngaphakathi kwi-`(Dermis)`:

• Imithambo yegazi: Le mithambo yegazi inika umaleko ongaphezulu, i-epidermis, izondlo kunye neoksijini. Esi sondlo sibalulekile ekukhuleni kweeseli ezintsha kwi-epidermis. Ngamanye amaxesha, xa sineentloni okanye sisoyika, ubuso bethu bujika bube bomvu kuba le mithambo yegazi iyavuleka.
• Iziphelo zemithambo-luvo: Njengoko sele sixoxile, yonke into esiyivayo, njengentlungu, ubushushu (obushushu/obubandayo), uxinzelelo, ukuchukumisa, njl.njl., yenziwa ibe nokwenzeka ziziphelo zemithambo-luvo kwi-`(Dermis)`. Ngaphandle kwezi, besingayi kuva nto.
• Iindlala zokubila: Ezi ndlala zivelisa ukubila, okunceda ekulawuleni ubushushu bomzimba. Xa ukubila kuphuma eluswini, kuyawupholisa umzimba.
• Iifollicle zeenwele: Zonke iinwele emzimbeni wethu ziqala kwifollicle encinci kwidermis. Ingcambu yeenwele ilapha.
• Ii-sebaceous glands - Abavelisi beoyile yolusu: Ezi glands zivelisa into enamafutha ebizwa ngokuba yi-sebum . Le sebum igcina ulusu luthambile kwaye lufumile. Ikwanceda ukugcina ulusu lungangeni manzi. Ngamanye amaxesha, i-sebum eninzi inokubangela i-acne.

`(Izicubu ezingaphantsi kolusu)` (izicubu ezingaphantsi kolusu) - ukhuseleko kunye nobushushu bomaleko onzulu

Ngoku sifika kumaleko onzulu, okanye asezantsi, eluswini. Oku kubizwa ngokuba yi-" Subcutaneous tissue" okanye ngamanye amaxesha yi-"Hypodermis". Ilele phantsi kwe-"Dermis", ngqo ngaphezu kwemisipha namathambo.

Olu maleko lwenziwe ngamafutha ikakhulu. Olu maleko lunamafutha lusinika iingenelo ezininzi:

• Ukhuseleko olufana nomqamelo: Ukuba siwa okanye sibethe into ethile, iyayifunxa loo ngxaki ngaphandle kokuyonakalisa ngqo amathambo okanye amalungu angaphakathi, isinika ukhuseleko olufana nomatrasi.
• Igcina umzimba ufudumele: Olu maleko wamafutha lusebenza njenge-'insulator', luthintela ubushushu bomzimba ukuba bungaphumi, lusinceda ekusikhuseleni ekubandeni nasekusigcineni sifudumele. Yiyo loo nto izilwanyana kumazwe abandayo zinomaleko omkhulu wamafutha emizimbeni yazo.
• Ukugcina amandla:Amandla agcinwa kolu maleko njengamafutha ukuze asetyenziswe xa kufuneka. Kulapho umzimba ufumana khona amandla xa singatyi.

Ngoko ungabona indlela ezi zinto zintathu zolusu ezibaluleke ngayo, nendlela ezidibene ngayo, nendlela ezisebenza ngayo emizimbeni yethu.

Ngoko ke, yintoni umyalezo esiwuthathayo kwizinto esizifundileyo namhlanje?
