Kumvetsetsa Ntchito ya a Jejunum
Jejunamu ndi gawo lapakati la matumbo aang'ono, kulumikizana ndi duodenum ndi ileum. Utumbo wawung'ono uli pakati pa mamita 22 ndi mamita 25, ndipo umapangidwanso kangapo; jekisamu ndi pafupifupi mamita asanu ndi atatu pa wamkulu wamkulu.
Ntchito ya Jejunum
Jejunamu, pamodzi ndi ziwalo zina za m'mimba, zimayambitsa kudya zakudya zowonjezera m'magazi.
Jejunamu imatha kutenga zakudya izi chifukwa zimayikidwa ndi mapiritsi omwe amatchedwa villi. Villi imatenga zakudya monga mchere, electrolytes, ndi chakudya, mapuloteni, ndi mafuta omwe amadya ngati chakudya. Zakudyazi zimalowa m'magazi momwe angagwiritsire ntchito mphamvu ndi thupi lonse.
Jejunamu, komanso m'mimba mwazing'ono, zimathandiza kusintha chakudya mu mphamvu, kupatsa thupi ntchito zofunikira tsiku ndi tsiku. Popanda intestine yaing'ono, chakudya chikanadutsa m'thupi koma sitidzakhala ndi zakudya zokha, ndipo tidzakhala ndi njala.
About the Jejunum
Jejunamu imayamba pa mitsempha yowopsya ya duodenum. Minofuyi imasonyeza mapeto a gawo loyamba la matumbo aang'ono ndi chiyambi cha jejunum. Palibe chidziwitso chodziwika kuti duodenum chimatha ndi gawo lotsiriza la m'matumbo aang'ono, leamu ikuyamba.
Mofanana ndi matumbo ena onse, jejunamu imaphimbidwa ndi membrane yochepa yotchedwa mesentery. Kuwonjezera pa kuthandizira jejunamu, mcherewu umatsitsimutsa jaiyam, kumathandiza kuti ukhale wotentha. Minofu mu jejunum imathandiza kusunthira chakudya kudzera m'thupi.
Kusokonezeka kwa Jejunum
Monga gawo la matumbo aang'ono, jejunamu imakhala ndi mavuto ambiri.
Zina mwa izi, malinga ndi US Library of Medicine, zimati:
- Kusuta
- Matenda a Celiac
- Matenda
- Kansa ya m'mimba
- Kutsekera m'mimba
- Matenda owopsa a m'mimba
- Zilonda, monga zilonda zam'mimba
Matenda a Crohn, omwe amatenga kutupa kwa matumbo, akhoza kutenga mitundu yambiri kuphatikizapo Jejunoileitis. Mujjunoileitis, jejunamu ili ndi moto; Zizindikirozi zimaphatikizapo ziphuphu, ululu, ndi kutsekula m'mimba.
Udindo wa Jejunamu mu Opaleshoni Yopweteka Kwambiri
Kuchita opaleshoni yachipatala ndi njira yogwiritsira ntchito matenda osiyanasiyana koma amadziwika bwino ngati chida chochepetsa kuchepa kwa anthu olemera kwambiri. Roux-en-Y ikuphatikizapo njira yowonjezera yomwe imaphatikizapo imayamba ndi "kusinthanitsa m'mimba" kumene kukula kwakukulu kwa m'mimba kumachepetsedwa kwambiri. Kenaka, mimba yatsopano, yaing'ono imachotsedwa kumbali yoyamba ya intestine yaing'ono (duodenum) ndi kubwereranso ku junium.
Pali zotsatira ziwiri zofunika kuchokera ku mtundu uwu wa opaleshoni. Choyamba, thumba laling'ono la m'mimba lingakhale lochepa, motero kuchepetsa chiwerengero cha makilogalamu amalowa. Chachiwiri, pamene chimbudzi chikudutsa duodenum, kuchepetsa zakudya ndi zakudya zimakhala zochepa. "Malabsorptive" chimbudzi chimathandizanso kuchepa kwa thupi - komabe, imathandizanso kuchepetsa kuchuluka kwa zakudya zomwe zimapezeka thupi.
