Sebopeho le mosebetsi wa trachea ho

Trachea - e le karolo ea bohlokoa haholo ea pampitšana matšoafo hore connects ho larynx ho bronchi ena. Ke hore a habonolo feta moea, hammoho le chelete e tse hlokehang bakeng sa oksijene. The trachea ke tubular sekoti lekala. Bolelele ba tube, ho ranges ho tloha disentimetara 8,5 ho 15, ho itšetlehile ka physiology ea phelang. Empa pele ho hlahloba mosebetsi o ka sehloohong oa trachea ho, e lokela ho ba tloaelane le human anatomy lona.

Beha trachea sebaka. The trachea qala ka lefufuru cricoid ka bang boemong ba botšelela vertebra cervical. E leng karolo ea boraro ea phaephe e ka boemo ba lesapo la mokokotlo cervical, 'me ba bang kaofela - le sebakeng thoracic, moo trachea fella ka boemo ba bohlano thoracic vertebra. Karolong ena ea trachea e arola ka bronchi tse peli, eaba ba etsa fereko - e ke bifurcation ntlha, e leng e lohellana le khoro aortic.

Ha re nahana ka karolo cervical ea 'mele, ka pel'a ho ke ke e le karolo ea thyroid tsoelesa e. Ho pholletsa le khutlela ho tracheal tube, e haufi le metso. Lehlakoreng ka leng ke neuro-vascular sosobaneng, e kenyeletsang likhoele tsa methapo ea kutlo vagus, hare jugular mothapo le mothapo carotid.

Trachea: sebopeho. Ha re nahana ka karolo sefapano sa trachea, ho ka bonoa hore na le le dikarolo 'maloa - the mucosa sebele, submucosa, lefufuru karolo le adventitia. tracheal mosebetsi, joaloka tse ling tse leha e le efe 'mele karolo itshetlehile mohaho, ka hona ho ke ke ho hlokahala hore ho nahana ka karolo ka' ngoe ka ho qaqileng le ho feta.

Mucosa - emeloang ciliated stratified epithelium hore larileng ka ka lera basal. lisele tse Cilia susumelletsa ikutloeleng larynx ena. Ea ho hlophisoa e boetse e akarelletsa lisele tsa epithelial bakoang le mopotjoana hore secrete e nyenyane ea mucus. Ho na le endocrine lisele hlahisa serotonin le norepinephrine. Kamoreng e ka tlaase lera na le e ngata oa likhoele rekere. Ho na le boreleli, myocytes motho di kenngoa ka lesakaneng la.

Submucosal lera - le fibrous, hlephileng connective dinama tse nyenyane tse. Ho ka lera lena ke bongata ba masela methapo ea kutlo 'me lijana tse nyenyane mali hore ba na le boikarabelo bakeng sa molao oa tsamaiso le ajoa mali.

Hyaline lera lefufuru Ho thehoa ho tswa lefufuru fella, e leng lula a mabeli ho ba bararo karolo e itseng ea sedikiso tracheal tube,. Cartilages amanang pakeng tsa lithapo tsa ka circumferential. palo ea lefufuru batho Range ho tloha 16 ho 20. The thehoa membranous morao leboteng leo adjoins le metso. Kahoo, temana ea bolus ha e kena-kenana le tsamaiso e hema.

Adventitia tsa trachea le - e tšesaane connective dinama tse nyenyane tse selateng sa hore koahela phala ho tswa ho ka ntle.

Joalokaha u ka bona, le human anatomy ba trachea e ha ho joalo rarahaneng.

Tracheal mosebetsi. Mosebetsi o ka sehloohong oa ho tracheal tube, - e jereng moea ho matšoafong. Empa sena ha se ea litšobotsi tsohle tsa trachea ena.

Joalokaha ho se ho boletsoe, ho lera mucous e koahetsoeng ka ciliated tracheal (ciliated) epithelium, mekhatlo tse laela ikutloeleng le larynx le molomo cavity. Ho phaella moo, lisele tse mopotjoana secrete mucus. Ka mor'a ho kopana le moeeng ka trachea tsa 'mele tse nyenyane tsoang linaheng tse ling tse kang lerōle, likaroloana le aparela mucus motsamao oa cilia e sutumelletsa khutlela larynx le fetisa ka' metso ea. Kahoo, trachea etsa mosebetsi e sireletsang. Tabeng ea ho kopana le e khōlō 'mele baditjhaba khohlela reflex qala, e leng nakong eo trachea e tsesaane haholo ka lumen ena.

E le o tsejoa, tlhoekiso le ho futhumala ha moea le hlaha ka ho nasal cavity, empa mosebetsi ona nka karolo le trachea. Ho feta moo, resonator trachea nakong puo hobane sutumetsa moea ho lithapo ka lentsoe.

Ho akaretsa, re ka bona hore, ho sa tsotellehe sebopeho batlang e le bonolo, e trachea na palo ya mesebetsi ea bohlokoa haholo ntle le tseo ho ba teng ha ea phelang batho ke ke ha khoneha.
