Pancreatic kua txiv: hauj lwm, muaj pes tsawg leeg, muaj nuj nqi thiab nta

Pancreatic kua txiv - ib tug ua kua uas yog ua los ntawm lub pancreas. Nws nco alkaline, ntshiab tsis muaj kob kua. Lub caj pas nyob qab lub peritoneum, thiab txuas mus rau lub caj qaum ntawm lub 1 thiab 2 nyob rau hauv lub lumbar vertebrae. Roughly, rau ib tug neeg laus, nws loj yog 80 grams, thiab 22 cm ntev. Lub txiav muaj ib lub taub hau, lub cev thiab tus Tsov tus tw. Nws muaj glandular cov ntaub so ntswg thiab excretory ducts. Raws li qhov tseeb kev kho pancreatic kua txiv mus rau hauv lub duodenum. Yuav ua li cas ib feem ntawm nws yog, thiab dab tsi yog qhov muaj nuj nqi ntawm lub cev? Qhov no yog tam sim no thiab yuav tsum tau tham.

Muaj pes tsawg leeg ntawm pancreatic kua txiv

Muaj pes tsawg leeg ntawm pancreatic kua txiv muaj xws li cov nram qab no Cheebtsam:

• creatinine;
• uric acid;
• urea;
• ntau yam txoj lw ntsiab.

Ib tug neeg ib hnub twg ua txog 1.5-2 liv cov pancreatic kua txiv. Tso pa tawm ntawm lwm yam uas lub paj hlwb thiab endocrine systems. Nrog ib tug loj tus naj npawb ntawm pancreatic kua txiv, uas allocates hlau tsim mob thiab ntev pancreatitis theem. Nrog ib tug tsis muaj pa ntawm ib tug neeg poob ceeb thawj sai sai, txawm hais tias nws muaj ib tug muaj zog qab los noj mov, thiab noj ib tug ntau. Qhov no yog vim lub fact tias cov zaub mov yog tsis zoo digested cov nyob rau hauv lub cev. pancreatic kua txiv plays ib qho tseem ceeb luag hauj lwm nyob rau hauv lub plab zom mov ntawm cov zaub mov. Nws muaj feem ntau muaj xws li dej. Yog li, hais txog 98 feem pua yog cov nyob rau hauv nws thiab 2 feem pua ntawm qhov seem uas organic Cheebtsam.

Pancreatic kua txiv thiab enzymes

Cov enzymes ntawm pancreatic kua txiv yog muab faib ua ob pawg: organic thiab inorganic. Organic muaj xws li:

• chymotrypsin;
• trypsin;
• phospholipase;
• elastase;
• carboxypeptidase thiab lwm yam enzymes nyob rau hauv daim ntawv ntawm cov zymogens, muaj cov cuab yeej ntawm cleaving cov nqaijrog, nqaijrog thiab carbohydrates nyob rau hauv tus txheej txheem ntawm kev zom.

Los ntawm inorganic enzymes muaj xws li:

• amylase;
• maltase;
• lactase;
• lipase.

Pancreatic enzymes no txhoj puab heev txaus. Yog li ntawd, lub caj pas ua trypsin inhibitor los mus tiv thaiv nws tus kheej-kev zom cov hlwb.

Pancreatic kua txiv: muaj nuj nqi

Rau tib neeg txiav nws yog ib yam uas tseem ceeb heev thiab ua ntau pab zog. Ua ntej ntawm tag nrho cov, nws ua ib tug dej uas yuav tsum tau mus zom zaub mov. Nrog xws zog zaub mov nkag mus rau hauv lub plab, nws yog siv rau yam uas tom qab faib thoob plaws hauv lub cev. Ua tswj ntawm digestive pancreatic kua txiv. Hais tias nws muaj tag nrho cov tsim nyog enzymes zom. Nws yog ib qho tseem ceeb uas lub acidity ntawm cov pancreatic kua txiv yog tsis qis tshaj li 7, pH 5 thiab saum toj no pH 8.5. Pancreatic kua txiv (pancreatic kua txiv) yog tsim nrog txhua yam khoom noj kom tsawg mus rau hauv lub plab thiab yuav tseem ceeb nyob rau hauv tus txheej txheem ntawm kev zom.

Tshwj xeeb tshaj yog zoo plab zom mov

Pancreatic kua txiv mus rau sawv tawm nyob rau hauv coob txaus, thiab cov plab zom mov txheej txheem yog ceev thiab ntseeg nkaws, nws yog tsim nyog los ua raws li kom thiab noj qab nyob zoo noj cov zaub mov, sim kom tsis txhob noj ntsim, kib thiab zaub mov. Cov khoom noj ua rau ib tug muaj zog load rau hauv cov hnyuv thiab plab, uas yuav cuam tshuam rau unfavorable ua hauj lwm ntawm lub pancreas.

Nta kua txiv uas ua lub pancreas

Muaj peb lub ntsiab theem ntawm kev loj hlob ntawm pancreatic kua txiv:

Paj hlwb. Nws yog raws li nyob rau hauv ib tug nyob ntawm thiab unconditional reflexes. Yog xav thov zwj ceeb:

• lub visibility ntawm cov zaub mov;
• nws tsis hnov tsw;
• ua noj ua haus cov txheej txheem;
• hais los ntawm lub zaub mov qab.

Nyob rau hauv cov ntaub ntawv no, lub pancreatic kua txiv yog tso tawm nyob rau hauv tus ntawm paj impulses uas los ntawm tus cortex rau lub caj pas. Yog li ntawd, qhov no yog hu ua conditioned reflex.

Los ntawm unconditioned reflex los muaj xws li cov zus tau tej cov pancreatic kua txiv thaum lub sij hawm stimulation ntawm khoom noj khoom haus lub caj pas thiab lub qhov ncauj kab noj hniav.

Lub hlwb theem luv luv-lived thiab nws ua me ntsis kua txiv, tab sis ib tug loj tus naj npawb ntawm enzymes.

Pais plab. Qhov no theem raws li nyob rau hauv lub stimulation ntawm lub receptors ntawm cov zaub mov uas nkag mus rau hauv lub plab. Los ntawm no pog neurons thiab secretory fibers nkag mus rau prostate, qhov twg lub kua txiv yog tso tawm nyob rau hauv tus ntawm tshwj xeeb lawm gastrin. Lub pais plab theem nyob rau hauv lub kua txiv ib tug me ntsis ntsev thiab dej thiab ntau organic enzymes.

Plab hnyuv. Nws kis tau nyob rau hauv tus ntawm humoral thiab paj impulses. Nyob rau hauv cov kev tswj ntawm pais plab muaj pes tsawg leeg tso tawm rau lub duodenum thiab cov khoom ntawm tsis tiav zom cov zaub mov cov as-ham, cov kis mem tes tshwm sim nyob rau hauv lub paj hlwb, thiab ces lub caj pas, li no pib zus tau tej cov pancreatic kua txiv.

Nyhuv ntawm cov zaub mov nyob zus tau tej cov pancreatic kua txiv

Thaum lub sij hawm so lub pancreas tsis tsim pancreatic kua txiv. Thaum lub sij hawm noj mov thiab tom qab xaiv yuav nruam. Pancreatic kua txiv, tus nqi, ua nyob rau hauv kev sib raug zoo mus rau lub plab zom mov ntawm cov zaub mov, thiab qhov ntev ntawm tus txheej txheem nyob rau qhov tseem ceeb ntawm zoo ntawm cov zaub mov thiab nws cov qauv. Ib tug loj tus naj npawb ntawm pancreatic kua txiv yog tsim nrog rau kev siv cov mov ci thiab bakery cov khoom. Ib me ntsis tsawg nqaij, thiab heev me ntsis khoom noj siv mis. Pancreatic kua, uas sawv tawm rau lub processing ntawm nqaij thiab nqaij, ntau alkaline tshaj ib tug uas yog generated los ntawm lwm yam khoom. Thaum txoj kev siv cov zaub mov kua txiv nyob rau hauv nws muaj pes tsawg leeg muaj peb lub sij hawm ntau li ntau lipase (piv nrog cov tais nqaij).

Center ntawm lub digestive system muaj ib tug complex qauv, nws Cheebtsam yog pom nyob rau hauv ntau qhov chaw ntawm lub paj hlwb. Lawv muaj tag nrho cov interconnected nrog txhua lwm yam. Digestive Center muaj ntau nta. Peb yuav paub qhov txawv ntawm lawv xws li:

• muab kev koom tes nyob rau hauv cov kev cai ntawm lub cev muaj zog, absorptive thiab secretory kev ua;
• Pib ntsais koj teeb ntawm kev tshaib kev nqhis, satiety thiab nqhis dej.

Tshaib plab - yog lub xub ntiag ntawm ncus tshwm sim los ntawm qhov yuav tsum tau rau cov zaub mov kom tsawg. Nws yog raws li nyob rau hauv lub unconditioned reflex yog kis tau mus rau lub pancreas ntawm poob siab system. Nws yog zoo dua rau noj me me mov noj tsib zaug ib hnub twg. Tom qab ntawd, txiav yuav ua kom thiab tsis muaj kev txhaum.

Saib xyuas ntawm koj tus kheej thiab noj qab nyob zoo!
