Sakhiwo umsebenzi uqhoqhoqho

Kuqhoqhoqho - ingxenye ebaluleke kakhulu yobufakazi ipheshana zokuphefumula exhumanisa amalaka kuya bronchi. Kuyinto ukuba ukudlula kalula emoyeni, kanye lemali edingekayo umoya-mpilo. Uqhoqhoqho kuyinto isitho ijabulise eziyize. Ubude tube zokhahlamba kusuka amasentimitha 8.5 kuya ku-15, kuye ngokuthi izitho zomzimba umzimba. Kodwa ngaphambi kokufunda umsebenzi oyinhloko uqhoqhoqho kumele ayejwayele nokwakheka kwayo.

Beka kuqhoqhoqho indawo. Uqhoqhoqho liqala uqwanga cricoid cishe ezingeni lesithupha vertebra wesibeletho. Ingxenye yesithathu tube kuyinto ezingeni yomgogodla wesibeletho, kanye nabo bonke abanye - esifundeni thoracic, lapho kuqhoqhoqho uphela ezingeni lesihlanu vertebra thoracic. Kulengxenye uqhoqhoqho ihlukane bronchi ezimbili, ukwakha ekuphambukeni - ke iphuzu bifurcation, okuyinto zithandelana lwaleli yomthambo i-aorta.

Uma sicabangela ingxenye wesibeletho yomzimba, ngaphambili it is a ingxenye indlala yegilo. Kuwo wonke emuva tube tracheal eyakhelene emphinjeni. On Uhlangothi ngalunye iyisixha Neuro-semithambo, okubandakanya Imicu emsipheni vagus, yangaphakathi umthambo jugular futhi carotid Umthambo.

Kuqhoqhoqho: isakhiwo. Uma sicabangela Ingxenye evundlile uqhoqhoqho kungabonwa ukuthi siqukethe izingqimba eziningana - le mucosa langempela, submucosa, uqwanga ingxenye futhi adventitia. tracheal umsebenzi, njenganoma iyiphi enye ingxenye yomzimba zincike isakhiwo, Ngakho-ke kubalulekile ukuba sihlole ingxenye ngayinye ngokuningiliziwe.

Mucosa - emelelwa ciliated epithelium wakubo ukuthi amanga on ulwelwesi basal. Cilia amaseli iphokophele amalaka. Ukwakheka sihlanganisa EPITHELIAL stem cells futhi goblet ukuthi secrete esincane isikhwehlela. Kukhona amaseli endocrine ezikhiqiza serotonin futhi norepinephrine. Ulwelwesi engaphansi has a lot of imicu enwebekayo yezicubu. Kukhona bushelelezi, myocytes ngabanye ezibekwe umbuthano.

Submucosal ungqimba - a lunemicu okuxekethile ezicutshini. Kuyinto kule ungqimba kuyinto omningi walo izinzwa nezitsha ezincane igazi ukuthi banesibopho nemithethonqubo kanye kwegazi.

kwakhiwa Hyaline uqwanga ungqimba kusukela uqwanga akuphelele, okuyinto hlala ezimbili kwezintathu ingxenye selilonke tracheal tube. Cartilages exhunywe phakathi izintambo circumferential. Isibalo uqwanga kubantu isukela 16 kuya 20. Le kwakhiwa membranous kususwa udonga lwangemuva okuyinto adjoins emphinjeni. Ngakho, ukudlula bolus kungaphazamisi inqubo zokuphefumula.

Adventitia we kuqhoqhoqho - a mncane zezinzwa izicubu emgodleni ihlanganisa ipayipi kusukela ngaphandle.

Njengoba ubona, anatomy we kuqhoqhoqho akunjalo nzima.

umsebenzi Tracheal. Umsebenzi oyinhloko we-tube tracheal - Siyanda emoyeni emaphashini. Kodwa lokhu akulona zonke izici uqhoqhoqho.

Njengoba sekushiwo, ulwelwesi lwamafinyila embozwe ciliated tracheal (ciliated) epithelium, ukunyakaza okuyinto baqondiswa ekufezeni amalaka futhi ngalo ingaphakathi ngomlomo. Ngaphezu kwalokho, amaseli goblet secrete isikhwehlela. Ngemva ukuxhumana emoyeni kuqhoqhoqho zemizimba encane angaphandle ezifana nothuli, izinhlayiya kanye wasibekela isikhwehlela ukunyakaza cilia bephushelwa emuva ku amalaka, badlulele emphinjeni. Ngakho, kuqhoqhoqho eyenza umsebenzi zokuzivikela. Uma ukuxhumana elikhulu nomzimba angaphandle ukukhwehlela reflex iqala, phakathi kwesikhathi lapho kuqhoqhoqho iyincane kakhulu mafutha anciphisa isikhala esingaphakathi.

Njengoba yaziwa, ukuhlanzwa kanye Ukushisa air kwenzeka ngaphakathi komgodi acinene, kodwa lo msebenzi uthatha ingxenye kanye kuqhoqhoqho. Ngaphezu kwalokho, i-kuqhoqhoqho elalinembobo ngesikhathi inkulumo ngoba odlulela emoyeni ukuze yezwi.

Kufinyeta, singakwazi ukubona ukuthi, naphezu isakhiwo elula, uqhoqhoqho enezinto eziningi imisebenzi ebaluleke kakhulu ngaphandle lapho ukhona umzimba womuntu akunakwenzeka.
