'Ole a me ka hana ana o ka trachea

Trachea - He mea nui loa o ka naehana'āpana e hoʻohuiʻia ka larynx i ka bronchi. He no ia, e hiki wawe ka hele i ka lewa, a me ka mea i koi 'nui o ka oxygen. Ke trachea mea he omo puha hui,. Ka lōʻihi o ka Tube papa koa mai ka 8.5 hiki i 15 mau kenimika, ke kaumaha ma muli o ka physiology o ka meaola. Akā, ma mua o ka papa hana o ka trachea noonoo, e e maʻa a me kona'anatomia.

E kau trachea wahi. Ke trachea hoʻomaka i ka cricoid cartilage ma e pili ana i ke kiʻekiʻe o ka ono cervical vertebra. Ke hapakolu o ka Tube mea ma ka pae o ka cervical spine, a me ka poe i koe - i loko o ka thoracic'āina, kahi a ka trachea welau i ka pae ana o ka lima thoracic vertebra. Ma keia pauku o ka trachea i hookaawale ai i loko o nā bronchi, ho okumu i kekahi ke'ō - ka mea, o ka bifurcation wahi, a ua intertwined me ka aortic e pio.

Inā ka cervical hapa o ke kino, ua noonoo, o ka mua o ia i kekahi hapa o ka thyroid gland. Ma ke kua i ka tracheal şarkı mea e pili i ka esophagus. Ma kēlā me kēiaʻaoʻao o ka neuro-vascular puapua, i nā olona, o ka vagus nā aʻalolo, kūloko ma jugular aa koko a me ka carotid artery.

Trachea: 'ole. Inā ka pauku kea o ka trachea mākou noonoo, ka mea hiki ke ike i ka mea he o kekahi mau papa - ka maoli mucosa, submucosa, cartilage kuleana, a me ka adventitia. tracheal papa, e like kekahi 'ē kino hapa hilinaʻi ma luna o ka' ole, no laila hoi e pono e noonoo kēlā me kēia 'ana i loko o hou au mamuli.

Mucosa - poe ciliated stratified epithelium e moe ana ma ka basalʻili lahilahi. Cilia keena neʻe i ke larynx. Ka haku mele 'ana i ka loaʻa o epithelial anei i keena a me ka poepoe lā ia e pee no he uuku nui o ka mucus. Aia i endocrine aeee i paka serotonin a me ka norepinephrine. Ka hale ilaloʻili lahilahi i ka hailona o laholio olona. Aia nō i laumania, kanaka myocytes i hoonoho iho i loko o ka kaiapili.

Submucosal, ahu iho - he fibrous, e wehe ai i connective'aʻaʻa. Ia mea i loko o kēia ahu iho o ka bulk o ke aʻalolo olona, a me ka mea uuku ipu koko i ka mea kuleana i ka rula a me ke koko holo.

Hyaline cartilage, ahu iho ua hana mai kāpili cartilage, i lilo ai elua-hapakolu hapa o ka tracheal şarkı anapuni. Cartilages e pili ana ma waena o na kaula i ka circumferential. Ka helu o ka cartilage ma ka hopena o ka ÷ 16 a hiki i 20. Ka hana membranous hope paia i adjoins ka esophagus. Penei, o ka hooholo ana o ka bolus, aole ia i ālai ia 'aʻe i ka ÷ naehana hanu kaʻina.

Adventitia o ka trachea - he lahilahi connective'aʻaʻa wahi e uhi i ka paipu, mai ka waho.

E like me 'oe ke ike, i ka'anatomia o ka trachea ua ole no laila, huikau.

Tracheal kuleana pili i. O ka papa kuhikuhi hana o ka tracheal şarkı - e hali ana i ke ea i ka ia maʻiʻaʻai. Akā, i kēia mea,ʻaʻole i nā hiʻona o ke trachea.

E like me ua oleloia, ua uhiia i ka mucousʻili lahilahi me ciliated tracheal (ciliated) epithelium, neʻe i i kauohaia i ka larynx a me ka moʻolelo lua. Eia hou, i ka poepoe lā ia keena pee mucus. Ma hope o hui 'ana me ka lewa i loko o ka trachea o liʻiliʻi haole kino e like me ka lepo, (particles) a me Hoamakeikekula mucus holo o ka cilia ua pahu hoʻi i loko o ka larynx, a hele aku i loko o ka puu. Penei, trachea hanaʻia he aiiay kuleana pili i. I Ina o ka hui 'ana me ka nui o nā haole kino cough reflex hoʻomaka, oiai i ka trachea mea nuiʻololī i loko o ka lumen.

E like me ua ikeia, hoʻomaʻemaʻeʻiaʻana a me ka mehana ponoʻana aʻe o ka ea ia lŘlŘ i loko o ka nasal lua, akā, i kēia kuleana pili i kuleana, a me ka trachea. Eia hoʻi, he resonator trachea i olelo no ka mea, pushes lewa i na kaula vocal.

E hōʻuluʻulu manaʻo, ua hiki ke ike ia, hoʻowahāwahā ka kŘpa a na mea 'ole, ka trachea i ka helu o ka mea nui i hana' ole i ke ola ana o ke kanaka meaola mea hiki ole.
