Injeke Anatomy: Imisebenzi kunye nezifo

Le ndlala inkulu emzimbeni wethu - isibindi nepancreas. Anatomy of the amalungu eziphambili inkqubo yokwetyisa inomnye umsebenzi umdla. Ezi luqinisekisa kwakheka ngexesha nophuhliso umbungu eludongeni duodenum. Ke, ngokuthe ngcembe landayo Luyimfuneko ke ukuya kude kuyo.

Le yesibini ngobukhulu nobubovu ye wokugaya phecana lo injeke, anatomy, umsebenzi nezifo eza kuxutyushwa kweli nqaku. Kuyinto yesibini kuphela ubungakanani kwesibindi. Le injeke ibekwe ndzhendzheleko le duodenum, phambi kwayo - umphezulu esezantsi esiswini. Kungenxa kule ndawo intle lo mzimba, kwaye wafumana igama layo.

Le injeke iye zombini yonyango kunye nemisebenzi exocrine. Last enze acini avelisa enzyme ezizodwa. Ixabiso eliphezulu le enzyme amylolytic kwaye lipolytic kunye trypsin. Bona secreted ngohlobo luyeke ukusebenza uze ezivulwa acini ngesiqhelo kuphela em- le duodenum. Ngokumalunga umsebenzi yonyango, ekuso i nemisele pancreatic (okanye nemisele Langerhans).

Pancreas: Anatomy

Xa abantu, le umzimba nesinqumka-emise. Intloko yakhe eqinileyo, yaye inxalenye eliphakathi ngaphezulu okanye ngaphantsi prismatic. umsila yakhe iingqameko. Wena ke mhlawumbi kalukhuni ngqondweni apho injeke. Nokwakheka zomzimba kulo, ke, kufuna ingqalelo eneenkcukacha.

Thina abanomdla umzimba phezu kodonga ngomva esiswini ethile kwinqanaba le-2 kunye 3rd empontshwa omqolo. Le injeke side ulwalathiso tyaba ukuze umsila wayo egqitha udakada, kwaye intloko ibekwe yomtya le duodenum. KwaNdlunkulu kwicala anteroposterior noko eqinileyo. It has a umhlehlo hook-ezimilise, uyalele phantsi. Njengoko umzimba zepancreas, ngokohlobo oko bemilo ngunxantathu. Peritoneum ifihle ngaphambili kobuso ejongene kumphezulu ngasemva isisu yethu. Oku abazahlulayo ukusuka yokugqibela umngxuma emxinwa ezingxobo ebezithunyelwe. Nepancreas (komzimba kuya kuba kucace kuwe, ukuba ufunda iifoto thaca kweli nqaku) yi wadibana kumphezulu elingasemva ingaba adrenal kunye ngohlangothi eliphezulu kidney ngasekhohlo.

Ubude umntu omdala malunga 15-25 cm kunye Ebubanzini -. Malunga 2-8 cm Ihlaziya injeke ukususela kuma-65 ukuya 160 g benozuko fresh, sime phandle, ezipinki-hina. Ukugubungela philisi yakhe mncane kakhulu.

Siye ingqwalasela ngokwemigaqo ngokubanzi, isakhiwo pancreas. Nokwakheka kwayo, kunjalo - abaliqela izihloko ezibanzi. Sikunika ngakumbi ukuhlola lo mbuzo.

Yobisi kunye nempahla emithanjeni

A ezininzi iinqanawa emithanjeni kunye imibhobho excretory uye pancreas. nokwakheka kwayo kwaye sijonge nabaqheleneyo nabo. Le imibhobho eziphambili excretory, ezivame ezimbini umntu ubaleka ukusuka emsileni ukuya intloko zepancreas, zidlula axis yayo. Amajelo Main isendleleni yayo ukuthatha amasebe ezininzi nowenziwa le lobules mfihlakalo. Baya kuma ngokucacileyo ezimhlophe sizoku lwisana na parenchyma pancreatic, nto leyo iba umbala zizimvi ezipinki. E ekudibaneni main ductless duodenum ubukhulu yayo ifikelela 3.2 mm. Ngomsila nomzimba babonelelwa inani amasebe kwemithambo splenic.

nepancreas Anatomy kuphawulwa bubukho kuthungelwano oxineneyo neempahla emithanjeni, nto leyo ngokusondeleyo kunye nothungelwano duodenum, inyongo lwesinyi inyongo imibhobho. Nkovu ngawo nokuphuma ukuya ezininzi iindawo nkovu yengingqi, apho zifumaneka esiswini, isango isibindi, mesentery, udakada washiya ingaba adrenal.

Sithemba ukuba uya ukuqonda komzimba ngesimo zepancreas.

innervation

Innervation umdla kuthi njengoko umzimba parasympathetic novelwano. imicu bezempilo Non-esinamanzi kufakwa kuyo ngokusebenzisa plexus perivascular. Kwimithambo- abakulo zepancreas, plexus abunjwe Ebubanzini nomphambili wayo kunye nomphezulu angasemva. luvo ngaphakathi kuyo, ezifanelekileyo imibhobho, neempahla, nemisele ka Langerhans kunye acini.

Indima neemvakalelo-luvo ekumiseleni umsebenzi secretory

Ekubeni ukuhlola okwenziwa I. P. Pavlovym, oko yasekwa into yokuba isenzo secretory kuyasebenza inhliziyo parasympathetic. abese Nerve zidlala indima ebalulekileyo ummiselo umsebenzi secretory zepancreas. Ukuba kukho ukungavisisani le luvo vagus , okanye xa umntu esebenzisa parasimpatikotronnye ezithile izinto amayeza granules secretory ukunyibilika ngokukhawuleza uze ume ngaphandle iiseli acinar. Noko ke, kule meko, incindi pancreatic utyebile nezinto eziphilayo kunye nee-enzayim, ngoko limi kwindawo mali kunokuba omncinane.

Ngakumbi nzima indlela ye ntshukumo amaza novelwano. Ngokutsho kwezinye iingxelo, ukuba luvo splanchnic bako aphazamiseke eyeyomzuzwana kwenzeka inhibition of secretion pancreatic. Noko ke, xa oko ilula zovuselelo elide Wabona umphumela efanayo ukukhuthazwa luvo vagus. Kufuneka kuqatshelwe ukuba nangokukrola kwimithambo- splanchnic kwaye vagus ukuba innervate ngaba umbutho umdla kuthi, akukuthinteli ukwahlulwa enzyme-rich incindi pancreatic. Oku kungenxa yokuba nje iintshukumisa zabo ukuvuselela secretion zepancreas. Esebenzayo entsonkothileyo neurohumoral indlela ukubaluleka lalo ukuya secretin. Le hormone ethile yenziweyo duodenum (i endometrium).

umsebenzi pancreatic

indima yakhe ukutya kunye ukwetyisa iphezulu kakhulu. Lomqulu ijusi pancreatic kungena duodenum. Le juice iqulethe enzayim ezifana lipase, trypsin, yelactose, maltase, kunye nabanye. Zithe inxaxheba kwiinkqubo yokwetyisa. Omnye umsebenzi obalulekileyo zepancreas - imveliso emzimbeni (glucagon, lipokoina, insulin). glucagon evelisa kunye insulin zisiwa ngqo egazini, umzimba silawula exchange otyebileyo carbohydrate emzimbeni. Ezi hormone kube nomphumela. Insulin kwandisa kunye glucagon kuphakamisa amaqondo eswekile yegazi. Ukutshintsha kumgangatho kunokukhokelela kwizifo ezifana nesifo seswekile.

pancreatitis

Ezinye meko ukuzinkcinkca ebomini (kukuzingxala ngokutya, ukusebenzisa kakubi utywala) zibe nefuthe elibi kwimpilo zepancreas. Baya kuba negalelo ekuveleni kwezifo ezifana pancreatitis. Kukukrala zepancreas. Pancreatitis ingaba oyingozi okanye engapheliyo.

pancreatitis yayiyazi

Yena ivela ngesiquphe. eziphambili iimpawu zayo - iintlungu, ngamanye amaxesha ukugabha, urhudo, ukuqunjelwa, ukudinwa, emaciation. Xa pancreatitis etsolo iintlungu ziviwa ngokubanzi kwicala lasekhohlo. Kuyaphela angazenza isimilo "aluzunguleza" intlungu. Ngamanye amazwi, ukuba utshisa kwicala lonke ekhohlo, uye emva.

Ukuba ngaba uneempawu ze-pancreatitis etsolo kufuneka udibane nogqirha, ngenxa yokuba esi sifo ayilwamkeli ngokwalo. Ukongeza, kusenokubakho iingxaki kakhulu. pancreatitis Acute ibandakanya ukonganyelwa yezigulane, intshayelelo iziyobisi zakhe etofayo ukunciphisa intlungu kunye nokudumba.

pancreatitis ezingapheliyo

Lubonakala yi ukuqhubela intlungu ayayo. Ngapha koko, ukuba aqhele phindwa amaxesha ngamaxesha (emva kakubi utywala okanye iimpazamo kwizidlo). Isifo akuthethi ukuba kufuneka uqhaqho olungxamisekileyo. Noko ke, oku akuthethi ukuba akukho mfuneko ukunyanga. Xa pancreatitis ezingapheliyo, kwakunye nawuphi na ukophulwa imisebenzi umzimba umdla kuthi, ukusilela kwinkqubo ekugayeni lwenzeka. Oku kuchaphazela impilo eziphilayo.

iswekile osegazini

Esi sifo kakhulu ngaphezu pancreatitis. Ukuza kuthi ga ngoku, ngelishwa, iyeza nangoku akazi ukuba ukunyanga njani. Diabetes sinwenwa ngenxa ukuhluleka emzimbeni we hormone enjalo ebalulekileyo, insulin. Ngenxa yokunqongophala layo lokugaya egxobhekile. Ephilayo ngaphandle insulin awukwazi ukugaya iswekile, owona mthombo enkulu amandla. Ngenxa yoku, oko konyusa inqanaba igazi, yaye ancedisana lifinyele. Seswekile kufuna esweni rhoqo.

Ekuphetheni

lungu kubaluleke kakhulu ke pancreas. komzimba womntu ngempazamo ifakiwe kwikharityhulam yesikolo eziphilayo. Ngamnye wethu ufanele ukwazi ngayo umzimba wethu, indlela amalungu ezahlukeneyo abasebenza. Xa iimpawu lokuqala lwesifo kubhetele ukuba udibane nogqirha. Ngapha koko, uthintelo usoloko kulula ukumnyanga ixesha elide.

Okwangoku, lokufunyaniswa imeko amalungu amaninzi, kuquka nezo umdla kuthi, esebenzisa ultrasound. Ngoko komzimba pancreatic zimelwe ngokwegrafu kwikhusi. Ultrasound omzimba - enye isixhobo zophando ezibiza imali encinane kwaye zithembekile practice clinical mihla.
