I-thermoregulation eyenziwa njani emzimbeni?

Umzimba womntu unokuhlala usebenza kwiindawo ezincinane zokushisa - ukusuka kwi -25 ukuya kuma-43 degrees. Ukukwazi ukuyigcina ngaphakathi kwezi mida kwanokuba utshintsho olukhulu kwiimeko zangaphandle lubizwa ngokuba yi-thermoregulation. Isiqhelo somzimba sikule meko kuluhlu oluvela kuma-36.2 ukuya kuma-37 degrees, ukuphambuka kwawo kubonwa njengophulaphulo. Ukufumana izizathu zolu hlobo lwezifo, kuyimfuneko ukwazi indlela ukuqhutyelwa kwe-thermalgulation eyenziwa ngayo emzimbeni, yiziphi izinto ezichaphazela ukutshintshwa kwamaqondo okushisa kwangaphakathi, nokuchonga iindlela zokulungiswa kwazo.

Kutheni ukutshatyalaliswa komzimba kwenziwa emzimbeni womntu?

Indlela echazwe ngayo ihamba ngeendlela ezi-2:

1. Ukufudumala kweMichiza yinkqubo yokuvelisa ukushisa. Iveliswa yizitho zonke zomzimba, ngakumbi xa igazi lidlula kubo. Uninzi lwamandla luveliswa kwisibindi kunye nemisipha.
2. Ukufudumala kwimoya yinkqubo yokukhululwa kweshushu. Yenziwa ngokutshintshisa ngokutsha ngokubhekiselele kumoya okanye izinto ezibandayo, imirhumo ye-infrared, kunye nokuqhuma kwe-sweat ebusweni lolusu kunye nokuphefumula.

I-thermoregulation igcinwe njani emzimbeni womntu?

Ulawulo lokushisa kwangaphakathi lubangelwa ngenxa yobuzwe beempawu ezizodwa zemitha. Inxalenye yazo inxalenye yesikhumba, iphepheni yokuphefumula kunye neembumba zomlomo zomlomo.

Xa izimo zangaphandle zihamba ngokuqhelekileyo, i-thermoreceptors ikhiqiza imiphumo ye-nerve engena emgodini womlanjana, emva kwee-bumps, i-hypothalamus, i-pituitary gland kunye ne-cortex ye-cerebral. Ngenxa yoko, ukuvakalelwa komzimba kubanda okanye kubushushu kubonakala, kwaye isikhungo sokufudumala siphucula iinkqubo zokuvelisa okanye ukukhulula ubushushu.

Kubalulekile ukuba uqaphele ukuba kwindlela echazwe ngayo, ngokukodwa-ukwakheka kwamandla, kwabandakanyeka ii-hormone ezithile. I-Thyroxin iqinisa umthambo, okwandisa ukuveliswa kobushushu. I-Adrenaline yenza ngendlela efanayo ngokuphucula iinkqubo zenkxaso. Ukongezelela, kunceda ukunciphisa imithana yegazi kwesikhumba, okuthintela ukukhululwa kweshushu.

Iimbangela zokuphulwa komzimba

Izinguqu ezincinci kumlinganiselo wokuveliswa kwamandla ashushu kunye nokutshintshwa kwendawo yangaphandle kwenzeka ngexesha lomzimba. Kule meko, oku akusiyo i-pathology, njengoko i-processor thermoregulation yabuyela ngokukhawuleza, ngexesha lokuphumla.

Uninzi lwezophulo ezicatshangelwayo zizifo zesistim, zihamba neenkqubo zokuvuvukala. Nangona kunjalo, kwiimeko ezinjalo, ukwanda kwomeko lokushisa komzimba kungabizwa ngokungafanelekanga ngokusesikweni, kuba umkhuhlane kunye nomkhuhlane uvela emzimbeni ukucima ukwanda kwamaseli e-pathogenic (ii-virus okanye ibhaktheriya). Enyanisweni, le ndlela yindlela ekhuselekileyo yokukhusela.

Ukuphulwa okwenyaniso kwe-thermoregulation kuhamba nomonakalo kwizitho ezijongene nokuphunyezwa kwayo, i-hypothalamus, i-pituitary gland, intambo yomgudu kunye nengqondo. Oku kwenzeka ngoomatshini ukuxhwaleka, ukubola, ukubunjwa kwezidumbu. Ukongezelela, izifo ze-endocrine kunye ne-cardiovascular disease, izifo ze-hormonal, i- hypothermia ngokomzimba okanye ukugqithisa komhlaba kunokunyusa ukukhubazeka.

Unyango lokuphulwa kwe-thermoregulation evamile emzimbeni womntu

Kunokwenzeka ukubuyisela inkqubo efanelekileyo yeendlela zokuvelisa nokubuyela kobushushu kuphela emva kokugqiba izizathu zenguqu zabo. Ukuze wenze ukuxilongwa, kufuneka uvakashele i-neurologist, uthathe inani leemvavanyo zesebhoratri kwaye wenze izifundo zesebe ezinikezelweyo.
