Ubume kunye nomsebenzi uqhoqhoqho

Uqhoqhoqho - siyinxalenye ebaluleke kakhulu phecana nokuphefumla lebhokisi kwingqula ukuya bronchi. Kungenxa ukuba kudlula ngokulula nomoya, kunye nemali efunekayo ye-oksijini. Uqhoqhoqho na ilungu tubular umngxuma. Ubude ityhubhu isusela ukusuka iisentimitha 8.5 ukuya 15, kuxhomekeke amalungu yento ephilayo. Kodwa phambi kokuba kucingwe nguwona msebenzi uqhoqhoqho, kufuneka babenolwazi kunye nokwakheka kwayo.

Beka indawo uqhoqhoqho. Uqhoqhoqho iqala kwi intlala cricoid malunga kwinqanaba lesithandathu vertebra wesibeleko. Isahlulo sesithathu ithumbu kwinqanaba yomqolo wesibeleko, yaye abanye - kummandla thoracic, apho uqhoqhoqho uphela kwinqanaba le vertebra yesihlanu thoracic. Kweli candelo uqhoqhoqho ihlukane bronchi ezimbini, ekusekeni ifolokhwe - oko kuyo bifurcation, nto leyo edibene Arch aortic.

Ukuba sicinga inxalenye wesibeleko lomzimba, phambi kwayo yinxalenye le ndlala lengqula. Kuyo yonke le umva ityhubhu tracheal ecaleni emphinjeni. Kwicala ngalinye a neuro nemithambo iinyanda, equka Imicu luvo vagus, ngaphakathi ndlela jugular kunye carotid umthambo.

Uqhoqhoqho: isakhiwo. Ukuba sicinga icandelo umnqamlezo uqhoqhoqho, kunokuthi kubonwe ukuba iqulathe lamanqanaba ezininzi - le isifo kanye, submucosa, intlala inxalenye kunye adventitia. umsebenzi tracheal, njengayo nayiphi na inxalenye yomzimba zixhomekeke isakhiwo, ngoko kuyimfuneko ukuba sihlole ingxenye ngokweenkcukacha.

Isifo - zimelwe epithelium wakubo ciliated ukuba ulala phezu ndizayo Uhlobo Lokuqala. iiseli isiliya aye kwingqula. Ukubunjwa kwakhona iquka iiseli Isiqu epithelial kunye engenamqheba ukuba cell ukuba kukho imali encinane yencindi yomlomo. Kukho iiseli ezidalwe avelisa serotonin kunye norepinephrine. Le inwebu elingaphantsi has a lot of imicu elastic. Kukho smooth, myocytes ngamnye afakwa kwisangqa.

Submucosal layer - a ezinezikhondo, izicwili okubi nokuqina. Kungenxa kule nwebu nguye isambuku luvo kunye imithambo yegazi ezincinane inoxanduva lokulawula kunye nokuhamba kwegazi.

Hyaline intlala layer amiliswe ukusuka intlala engaphelelanga, leyo abahlala sisibini esithathwini inxalenye umtya ojikeleyo tracheal ityhubhu. Cartilages enxulumene phakathi nezintya circumferential. Inani intlala ebantwini aqala ku-16 ukuya 20. Udonga membranous wabumba ngasemva leyo ekufuphi nebheyi emphinjeni. Ngenxa yoko, ngecala elingaphesheya bolus ayihambelani kuphazamisana inkqubo sokuphefumla.

Adventitia ye uqhoqhoqho - enomzimba nokuqina lisesingxobeni inyama esigquma umbhobho evela ngaphandle.

Njengoko ubona, indlela ezakhiwe ngayo uqhoqhoqho akukho kangaka nzima.

umsebenzi tracheal. Umsebenzi ophambili ityhubhu tracheal - oyiphetheyo umoya emiphungeni. Kodwa oku zonke iinkalo uqhoqhoqho.

Njengoko sele kukhankanyiwe, i inwebu yangaphakathi ligutyungelwe epithelium ciliated tracheal (ciliated), iintshukumo leyo ijoliswe kwingqula kunye kwisisu ngomlomo. Ukongeza, iiseli engenamqheba cell yencindi yomlomo. Emva ukuqhagamshelana umoya uqhoqhoqho lwemizimba ezincinane amazwe afana njengothuli, amasuntswana kunye yencindi nentshukumo Imvulophu ye isiliya utyhalelwa umva kungena kwingqula, badlulele emqaleni. Ngenxa yoko, uqhoqhoqho ezisebenza umsebenzi olukhuselayo. Xa wadibana nomntu elikhulu umzimba langaphandle khohlo reflex luqala, ngexesha apho uqhoqhoqho onciphileyo kakhulu le mithambo.

Njengoko yaziwa, ukucocwa Ukufudumala umoya lwenzeka kwi lweHo- ngeempumlo, kodwa lo msebenzi kuthatha inxaxheba kunye noqhoqhoqho. Ngaphezu koko, a uqhoqhoqho resonator kwintetho kuba pushes umoya imisipha.

Ukushwankathela, siyabona ukuba, nangona isakhiwo elula, uqhoqhoqho kukho inani imisebenzi ebalulekileyo kakhulu ngaphandle apho ubukho umzimba womntu akunakwenzeka.
