Duct Thoracic: uphawu

является основным ее сосудом. Thoracic duct emithanjeni nkqubo usisitya yayo ephambili. Oko abunjwe ngeendlela ezininzi. Esiza kuxubusha ngayo ngokweenkcukacha oko duct thoracic.

nokwakheka

Eludongeni isitya zezi inwebu ezintathu: endothelial, izihlunu-fibrotic kunye yangaphandle. In kwemithambo zokuqala 7-9 langoku enkulu semilunar. Iintungu ezinezikhondo esingxotyeni ke emlonyeni sphincter. Adventitia (elingaphandle) ibambelela pleura, aorta kunye umqolo. Ukususela ekuqaleni kweli bile na esiswini ekwanti, thoracic, isebe wesibeleko. Le yokugqibela imelwe ngohlobo i arc, yaye ezimbini zokuqala - ngokohlobo inqanawa ngamaso ende ihamba aorta ukwehla. isabelo ngenzolo aortic udlula kulo lisikwe kwi uvalo kuloo ndawo ibinomthwebeba esifubeni. проходит по левой боковой плоскости нижних позвонков сзади от нисходящей аорты. Apha, i duct thoracic uhamba nxamnye kwicala lasekhohlo moya ka amathambo asezantsi emva aorta ukwehla. Ngaphezu koko, ukuba baphambuke kufutshane emphinjeni. Kule ndawo ziphatha 2-3-th thoracic iphuma kuvuleke iminxunya (udini lwalo ngasekhohlo). Waza emva eqhelekileyo kunye imithambo subclavian ayanyuka abe phezulu emngxunyeni. Okulandelayo, inqanawa iya ngeenxa phezulu umva kwicala lasekhohlo lwe pleura. в венозный угол либо ветви, формирующие его, - плечеголовную, подключичную, внутреннюю яремную. Apha, akha arc, duct thoracic ungena iengile lwemithambo okanye amasebe iyilwe nguye, - brachiocephalic, subclavian, jugular lwangaphakathi. Kwesi siza ngesitya wambumba valve semilunar kunye sphincter. в длину достигает 1-1,5 см, в редких случаях 3-4 см. ubude duct Thoracic ifikelela 1-1.5 cm, kwiimeko ezinqabileyo, 3-4 cm.

ukubunjwa

образуется: duct Thoracic ukhandwa:

1. Ekuhlanganisweni isisu, empontshwa okanye zombini, kunye nezinye emigodini kumacala omabini.
2. Ukwenziwa amasebe chylocyst. Kulo mzekelo, i duct thoracic ikhangeleka ampullar, ukwanda etsobhileyo.
3. Hlanganisa kuphela empontshwa kunye iziqu emathunjini.

может образовываться и как сетевидное начало в форме петлистого крупного сплетения из чревных, поясничных, брыжеечных ветвей и выносящих сосудов. duct Thoracic nazo kuyilwa njenge reticular-ezimile petlistogo phezulu plexus enkulu celiac, empontshwa, amasebe mesenteric kunye neempahla efferent.

Ezi nkcukacha lwesakhiwo

Ngokufuthi, ubume kunye nesimo sendawo lula ukumisela ubonisa. Ngokukodwa, ziphawuleka:

1. Ukuphinda thoracic okanye ukubunjwa imibhobho ezongezelelweyo (enye okanye ngaphezulu).
2. iinketho ezahlukeneyo intsebenziswano kunye pleura, aorta, imithambo ezinzulu wesibeleko, emphinjeni.
3. Intlanganisela in lwemithambo (jugular) angle, brachiocephalic, iphuma subclavian okanye umphanda enye ngaphezulu.
4. Imfundo ampule isabelo phambi kokungena iimpahla.
5. Nokungena nagaxeleka ezilingweni kwikona ndlela jugular okanye uyenze ngokwakho.

duct Thoracic: ekunene duct emithanjeni

Le element kwakhona uqwalasele ngeendlela ezahlukeneyo:

1. Ekudibaneni kwe subclavian, jugular, iziqu broncho-mediastinal. . Oku kwenza duct elifutshane kunye ngokubanzi thoracic. Le meko uyaqapheleka 18-20% yamatyala.
2. channel Ekunene kungangabikho. Sheaths ukuba ifomu yalo ukuvula ngqo kwi jugular okanye engile nempahla yaso candelo. Le meko uyaqapheleka 80-82% yamatyala.
3. Kukho ukwahlukana elifutshane kakhulu, ngokubanzi umjelo ekunene ngaphambi kokungena kwikona ku 2-3 kunye ngaphezulu eziqwini. Le kuvulwa kuthiwa ifomu reticular.

eziqwini

Bangabantu ezintathu:

1. esiqwini Jugular. Kuye kwasekwa ngokuzisa nezitya wesibeleko. Baya kuphuma kwiindawo ezinzulu lateral. Le isiqu ihamba Kusenjalo lwangaphakathi jugular ukuya ekoneni. Kweli candelo ayajika kuwo okanye igazi nempahla, iyilwe nguye, okanye ukuthatha inxaxheba ekubunjweni ijelo ekunene.
2. esiqwini Subclavian. Imbonakalo yayo ngenxa uhlangane izitya efferent lweendawo axillary. Umgqomo ubanjwa kufuphi Kwangale subclavian, kwaye isivingco sphincter. Kuvula okanye izitya lwemithambo kunye angle, oko kusenziwa okanye Isitishi ekunene.
3. esiqwini Bronhomediastinalny. It amiliswe empahleni efferent bronchopulmonary, tracheal, iindawo mediastinal. Kule kwathela kukho lwezivalo. Kuvula kungena ijelo ekunene, okanye engile jugular lwemithambo, okanye ezityeni, iyilwe nguye. Le yokugqibela ziquka brachiocephalic, subclavian, ndlela jugular.

iimpahla efferent Ekhohlo vula kungena duct thoracic. Ukususela tracheobronchial eliphezulu neendawo mediastinal ukuze engekabili ekujikeni lwemithambo. Komboko emithanjeni, njengoko kwi bile, kukho imifinya ezintathu: adventitia, kwimisipha endothelial-elastic.

imithambo yegazi imiphunga kunye ezalathelwe uphuhliso

Le emithanjeni zezilwanya networks ezimbini. One - ubuso - ifumaneka kwi pleura visceral. Okwesibini - anzongonzongo - luqokelelane malunga lobules pulmonary alveoli ezingqonge nempahla kunye namasebe omthi inyumoniya. network Surface imelwe indibanisela emithanjeni ezivaliweyo ububanzi. Yena umaleko ube mnye. plexus Capillary thaca kwi ifomu yaye yathunyelwa kuzo zonke iindawo kwi pleura visceral. Deep kuyinto inethiwekhi-ntathu. Njengoko inxalenye eyintloko yalo ezivelileyo plexus lobular. Bathumela izalathiso 2nd nkovu. Yena engena iimpahla pulmonary plexus kunye iityhubhu inyumoniya, kwaye kungena kuthungelwano pleural. amasebe Inzuzo zakheka kwinqanaba ceke, zingena portal kunye nokulingana. Baya kuphuma kwemiphunga, kunye imithambo kunye evulekileyo visceral kwi macandelo alandelayo:

1. Bronchopulmonary. Zahlula-hlulwe intraorganic kunye vneorgannye. Eyokuqala ise kwi equity kunye segmental bronchi, okwesibini - engunozala kwemiphunga.
2. phezulu Tracheobronchial kunye ezantsi. Baya kulala ngasentla ngezantsi bifurcation tracheal.

iimpahla Efferent iyangena sobuKristu mediastinum kunye tracheobronchial ezalathelwe. Kwezi, ukuba zivulwe buti bronhomediastinalny. Kwiimeko ezinqabe kakhulu, iimpahla ukuze kweyela duct thoracic kunye engile jugular lwemithambo.
