Yiyiphi indima kulusu thermoregulation: Ziphumo awohluke zenkqubo

Isikhumba ilungu elikhethekileyo komzimba womntu. Yaba yena okhonza nje umqobo yendalo kunye nokudibana phakathi kwayo kunye ngexesha elinye yonke imiba yokusingqongileyo. Kweli nqaku siza kujonga yintoni indima isikhumba kwi thermoregulation. Kwaye yintoni ke iimpawu ezifanayo kwesakhiwo, kufuneka ukuba enze lo msebenzi?

isikhumba Human: iimpawu zezakhiwo

Ewe, isikhumba - eneneni umzimba. Ngaphezu koko, le inkulu emzimbeni womntu. ubunzima wawo omdala emithathu kg, kwaye yendawo square metres emibini. Kodwa ububanzi encinane ulusu - 5 mm. Kwaye iindawo ezahlukeneyo eli xabiso ungahluka. Kuxhomekeke umthwalo. Apho inkulu, isikhumba ziyatyeba kunye coarser. Umzekelo, kwi iintende zeenyawo. Kwaye apho kukho ukukhuhlana sakugcina - thinner. Isikhumba nayo okuthathwa avela kulo. Xa abantu, oko iinwele kunye nezikhonkwane.

Ulusu wenza imisebenzi ebalulekileyo. Ba yokhuselo, izifo, excretory, yokucolwa kunye zokwenziwa. Kodwa ukuze siqonde ukuba yintoni indima kwesikhumba thermoregulation, kuyimfuneko ukuba siqwalasele iimpawu eziphambili ubume komzimba.

sangaphandle

Umaleko engaphandle yesikhumba kuthiwa sangaphandle. Oku abunjwe ngokupheleleyo tyaba inyama epithelial. Lo maleko iquka iinxalenye ezimbini. Eyokuqala kuthiwa uphondo. It is a lot of iiseli abafileyo ukuba sloughed usuku ngalunye. Ke isikhumba sokurhuqa ngexesha elifanayo kungenzeki. Kwaye kwenzeka ngenxa yokuba sesigodlo ibekwe phantsi nwebu yesibini sangaphandle - Ekudubuleni. Le live, iiseli rhoqo ukulahlula ukuba ibe yinkqubo eqhubekayo yesikhumba kutsha.

eneneni isikhumba

Ngaphantsi sangaphandle lo dermis, okanye isikhumba ngokwayo. Le kwizicwili esixineneyo, oyinxalenye sisiseko ulusu yonke. Le nto ndiyibhalayo imicu collagen. Ngenxa kule inkalo, isikhumba elastic akafuni kwaphula phantsi nayiphi na intshukumo. Kukho izinto ezenza ukuqonda ngaphandle kwebala, iintlungu kunye notshintsho lobushushu, igazi kunye nkovu nempahla, iingxowa iinwele, ukubila kunye namadlala sebaceous.

inyama ongama adipose

Umaleko sinzulu isikhumba liquka izihlunu adipose phakathi imiqadi, okanye iiseli ngamnye. Nge olwenzeka ebonakalayo izondlo emzimbeni ubukhulu kwale maleko angandiswa ukuya ngokweesentimitha eziliqela. iinkqubo Thermoregulation, okunqanda umonakalo, ukunikwa ukutya ngexesha ethile - ezi mpawu ziphambili kwamafutha ongama.

Yintoni na le thermoregulation umzimba

Umntu sisilwanyana ezinegazi elishushu. Oku kuthetha ukuba ubushushu umzimba wakhe rhoqo kwaye luzimele utshintsho phantsi kweemeko zokusingqongileyo. 36.6 degrees - imigaqo izinga kwaziwa abantwana. Iimpawu thermoregulation oluntu kwaye rhoqo kwesi salathisi kunye nobushushu eshushu, nengqele kakhulu. Njani kunokwenzeka oku? Umzimba usoloko kudla izinto eziphilayo eziyinxalenye ekutyeni. Bona baphuke phantsi, yaye isiphumo energy thermal. Le nkqubo ubuyisela bume yayo kuthatha indawo ngokunxulumene nemithetho physics. Iqondo lobushushu umoya idla ngaphantsi kunolo umzimba. Ngoko ke, ubushushu uvela kummandla kunye zinga liphezulu hi ndlela leyi hambaneke. ie ubushushu unika umzimba. Ngenxa yoko, abantu kunye lobushushu lihlala rhoqo. Yintoni indima kwesikhumba thermoregulation? Yiyo lo mzimba imisela ngobunzulu yenkqubo. Kwimeko lobushushu ulusu nyangatseka iqala thermoreceptors reflex ukulondolozwa reaction ubushushu. Nantsi indlela yokwenjenjalo: iimpahla yegazi akhiwe dermis, ukuba iingqameko, nokuphuma igazi ngaphantsi sehlise izinga transfer ubushushu.

Kwiqondo lobushushu eziphakamileyo, ngexesha umthambo thermoregulation Indlela wenziwa ngokwahlukileyo. Kulo mzekelo, umzimba kufuneka ukuba ahlawule isixa esithile ubushushu ukuthintela nobushushu yayo. Kwiimeko ezinjalo, i receptors enezo olunye uhlobo. Bebona ubushushu, nto leyo luvo ngokwentshukumisa kwenzeka kwaye esihambelanayo reflex reaction. Ihlala isibakala sokuba iimpahla zithambe eluswini, isikhumba lifumana imali eninzi egazini kunye nokudluliselwa nobushushu rate ukunyuka. Ngoko ke, umzimba womntu usoloko ezimbini iinkqubo malungana yenzeke. Eyokuqala kwezi kuthiwa isizukulwana ubushushu. Kungenxa cleavage organic izinto macromolecular. Yesibini - ubushushu. It uwugcinayo ulusu kunye isixokelelwano sokuphefumla. Umahluko phakathi kwezi nkqubo zimbini kuthiwa thermoregulation.

Yintoni ukubaluleka thermoregulation

Ixabiso ngokuba ukusebenza thermoregulation yomzimba zibalulekile. Khawucinge ukuba iqondo lobushushu emzimbeni wethu kuxhomekeka kokusingqongileyo. Ngoko, kwi bubushushu obukhulu umzimba nje ukubulawa ngenxa iproteni into lisenza kutshatyalaliswa a lobushushu + degrees 42. Phantsi kwezi meko, inkqubo yenkxwaleko yabo - ukunyhashwa ingqibelelo yezinto asidi acid. Kungenjalo igazi bekuya nje engumkhenkce kwiinqanawa ngenxa yaso into intercellular - plasma, 99% amanzi. Kodwa oku akwenzeki ngomsebenzi ulusu elungelelanisiweyo luvo. Kodwa kuphela lobushushu kuchaphazela thermoregulation. Ngokuqinisekileyo bonke imincili uviwo ebila neentende zezandla kuphela. Kutheni le nto isenzeka? Eyona nto kukuba urhulumente unamadlala ezidalwe uloyiko hormone kumlanjana igazi, akhokelela vasodilation kwaye, ngenxa yoko, ukunyusa transfer ubushushu.

Siye sahlolisisa yintoni indima ulusu kwi thermoregulation emzimbeni. Le umzimba ilinganisa irisithi nobushushu output, kuqinisekiswe rhoqo lobushushu emzimbeni eziphilayo ezinegazi elishushu.
