Cecum: marongerwo kunovaka uye chikuru basa mumuviri

Tisati tataura pamusoro basa cecum nomuviri womunhu, zvakakodzera kuti ajekese chii. Saka cecum kunoonekwa sechinhu chikuru muura dhipatimendi pasi bofu bhegi serin'i mugove, wakareba zvinosiyana munzvimbo 3-8 masendimita Zviri cylindrical, dzinenge -. Cone mune rehurukuro. Pane chaizvo inonzwisisika mubvunzo aripiko bofu dumbu? Zvinofanira yakajekeswa kuti rusvingo rwaro undovakira inonyatsoenderana zvakasimba tsandanyama ari abdominal mhango (psoas uye iliacus), uyewo rusvingo mberi, akavapindurawo, ndiyo yakabatana Anterior abdominal pamusoro. Chete mhedziso: asi cecum nokushingaira anosimudzira zvomudumbu kwendangariro.

Kana isu kutaura kuonekwa kuti muitiro mhando ichi, zvinofanira kutaurwa kuti cecum akapoteredzwa kumativi ose nokuda peritoneum, uye rine honye-kufanana maatomu akafanana (okuwedzera), izvo zvinokosha chezvinonhuwira masoja kudzivirira. Izvi "chaikosha" iri ruzhinji kunotoda kurapwa mifananidzo iri mugwara iliac fossa, asi kunogonawo yekudyidzana dzinofamba mukati pelvic mhango. Vazhinji okuwedzera rine mesentery, kubatanidza pamwe ndege yacho cecum uye pose rokupedzisira ileum, uye mhango waro izere zvakawanda lymphoid zvinyama, zviri nevakawanda kwazvo nokuda kutapata.

Zvinofanira kucherechedzwa kuti nezera, kuti cecum yekudyidzana ikachinja chitarisiko. Somuenzaniso, mune vakwegura hazvina elongated uye rine rusvingo kusimba, uye vaduku vose kwazvo, uye "muitiro" kunoratidzwa kukura zviduku uye gobvu masvingo. Uyezve, sezvo makobvu, rine taenia caecum uye haustra, sezvamakaropafadzwa kuchinja kuchembera wechipiri kufumura muviri nokuti muviri ari muduku ivo kwakaratidza zvakajeka kupfuura vakwegura.

Zvakakosha kuziva kuti cecum racho histological Murongerwo haasi rakasiyana muura parusvingo, uye ayo mucous nokuumba pazvirugu duku, zvikurukuru, maviri kurova-rova-akafanana neboka predominance kuti tsandanyama fibers, uye imwe chete. Uyezve, mucosal akatonga Liberkyunovy shwanu uye masero wakanwa uye pasi zviri tunica submucosa, uko kunomiririrwa unzenza connective zvinyama, zvinosanganisira mafuta uye cellular Zvivako mvere tsandanyama fibers.

Achitaura pamusoro kugadzwa cecum, zvakakodzera kujekesa kuti avepo nedanho kugaya. Ziva kuti zvii chaizvo mashandiro ari cecum.

Sezvo chikazozikamwa, huru kubvisa kugaya uye mimwe kutsemura zvinhu zvakananga chinokurira iri ura duku uye cecal achiri kwazvinogumira enzymatic kugaya, asi saturation pamusoro pezvakaitwa kwakadaro hakusi kudaro chinokosha.

Nechekare nesayenzi nekusimba kuti anenge 3% kubva makabhohaidhiretsi uye mapuroteni ozeyewa uye kunakidzwa muura uye cecum ndiyo chete anokonzera Absorção de Água mvura asunungurwa kupinda ari ura duku panguva zvakananga kugaya. Liquid intestinal zviri muna uplink uye cecum rinova mukobvu, uye transverse muura fecal diffraction kuva nekuumbanidzwa kusachinja-chinja, kunatsiridza ari distal muura ari kupfuura batana. Kana isu nezvazvo dzayo indispensability, zvakakodzera ratidza chokwadi kuti basa rinokosha mumuviri womunhu cecum hakuiti kutamba, asi rinokosha zvikuru muviri chinhu - okuwedzera, lymphoid follicles izvo dzinoshanda anodzivirira kwendangariro. Ndosaka zvokurapa zvinyorwa zvakawanda akashuma kuti okuwedzera ari mhando Reserve kuti zvirwere.

Zvakakosha kuyeuka kuti cecum, kunyange zvayo kukura kwete vasingakoshi, pasi pathological urongwa, izvo kazhinji kunotoreva zvirwere zvakakomba.
