Qhov sib txawv tseem ceeb ntawm monogastric thiab polygastric digestive system yog raws li cov yam ntxwv ntawm lub plab. Qhov ntawd yog; Lub Monogastric digestive system muaj ib leeg-chambered plab thaum lub polygastric digestive system muaj plaub-chambered plab.
Lub plab zom mov yog qhov tseem ceeb uas sib txawv ntawm cov ruminants los ntawm cov tsis yog ruminants. Ruminants yog cov tsiaj uas muaj plaub-chambered plab. Nyob rau hauv sib piv, non-ruminants yog cov tsiaj uas muaj ib tug yooj yim lub plab nrog ib tug chamber. Cov ruminants raug kev zom zaub mov ntev dua. Yog li ntawd, qhov yuav tsum tau ntawm lub plab multi-chambered yog ib qho tseem ceeb heev nyob rau hauv ruminants.
Monogastric Digestive System yog dab tsi?
A monogastric digestive system yog ib qho system uas muaj lub plab ib leeg. Cov kab mob xws li nees, luav, dev, npua thiab tib neeg muaj lub plab zom mov monogastric. Nyob rau hauv ib tug monogastric digestive system, secretion ntawm gastric kua txiv thiab digestive enzymes yuav siv sij hawm qhov chaw nyob rau hauv ib tug ib-chambered plab. Tsis tas li ntawd, cov kab mob nrog lub plab zom mov monogastric tsis tuaj yeem zom cov cellulose. Txawm li cas los xij, vim muaj cov kab mob cellulose-degrading plab, cov kab mob monogastric tuaj yeem zom cov cellulose. Yog li, microbial fermentation tshwm sim nyob rau hauv monogastric herbivores.
Daim duab 01: Monogastric Digestive System
A monogastric digestive system pib nws txoj haujlwm tam sim ntawd thaum nkag ntawm cov zaub mov rau hauv lub qhov ncauj. Cov qog secreting digestive kua yog stimulated thaum nkag ntawm cov zaub mov. Thaum thawj zaug txhua yam thiab tshuaj digestion tshwm sim nyob rau hauv lub qhov ncauj, cov zaub mov nkag mus rau hauv lub plab los ntawm esophagus. Cov zaub mov digestion tshwm sim nyob rau hauv lub plab, thiab thaum kawg, cov hnyuv me absorbs as-ham rau hauv cov hlab ntsha. Tom qab ntawd, cov khoom noj uas tsis tau digested raug tshem tawm ntawm lub cev los ntawm egestion. Tag nrho cov txheej txheem yuav tshwm sim los ntawm kev koom tes ntawm ntau yam digestive enzymes thiab secretions.
Polygastric Digestive System yog dab tsi?
A polygastric digestive system yog ib qho system uas muaj plaub-chambered lossis ntau lub plab. Daim ntawv no ntawm lub plab zom mov muaj ntau ntawm cov ruminants xws li nyuj, yaj thiab mos lwj. Plaub chav hauv plab yog hu ua rumen, reticulum, omasum thiab abomasum. Tsis tas li ntawd, lub xub ntiag ntawm plaub chav kuj tso cai rau kev zom tag nrho ntawm cov khoom noj uas muaj cellulose uas tau noj los ntawm ruminants.
Daim duab 02: Polygastric Digestive System
Cov kab mob uas muaj cov kab mob hauv plab zom mov tsis ua rau muaj kev zom zaub mov thiab tshuaj lom neeg hauv lub qhov ncauj. Hloov chaw, lawv nqos lawv cov zaub mov ntau heev, tso cai rau ib feeb zom cov txheej txheem. Thaum lub sij hawm, lawv yuav ruminate los yog nqa rov qab cov zaub mov nqos, ntxiv zom nws thiab nqos dua. Lub npas ntawm cov zaub mov uas nqa tuaj thiab rov zom dua yog hu ua cud.
Ntxiv mus, cov kab mob rumen ua lub luag haujlwm tseem ceeb hauv kev zom cov cellulose. Lawv koom nyob rau hauv tag nrho digestion ntawm cellulose, converting cellulose rau volatile fatty acids. Cov omasum thiab cov abomasum feem ntau koom nrog hauv kev sib tsoo ntawm cov khoom noj.
Dab tsi zoo sib xws ntawm Monogastric thiab Polygastric Digestive System?
- Ob leeg muaj cov qauv xws li qhov ncauj, plab, plab hnyuv, plab hnyuv loj, qhov quav thiab qhov quav.
- Lawv tau txais cov khoom noj khoom haus holozoic.
- Ntxiv mus, ob lub tshuab zais ntau yam enzymes thiab tshuaj rau cov txheej txheem ntawm kev zom zaub mov.
- Cov tshuab no muaj nyob rau hauv kev txiav txim siab dua eukaryotes uas yog lub nceeg vaj Animalia.
- Ob lub tshuab muab lub zog thiab cov khoom noj tsim nyog rau kev loj hlob.
- Ntxiv mus, ob lub tshuab yog kho los ntawm ob qho tib si lub cev thiab tshuaj lom neeg zom zaub mov.
Qhov txawv ntawm Monogastric thiab Polygastric Digestive System yog dab tsi?
Qhov sib txawv tseem ceeb ntawm monogastric thiab polygastric digestive system yog tus naj npawb ntawm cov khoom hauv plab. Cov kab mob Monogastric muaj ib lub plab hauv plab thaum cov kab mob polygastric muaj ntau lub plab. Txawm hais tias tsis yog-ruminants koom rau hauv pawg monogastric, ruminants koom rau pawg polygastric. Vim muaj kev hloov pauv ntawm lawv lub plab zom mov, txoj hauv kev uas lawv tau ua tiav cov txheej txheem digestive thiab lawv cov khoom digestive kuj sib txawv.
Cov hauv qab no qhia txog qhov sib txawv ntawm monogastric thiab polygastric digestive system.
Summary – Monogastric vs Polygastric Digestive System
Monogastric thiab polygastric digestive systems yog ob pawg tseem ceeb ntawm kev zom zaub mov raws li lawv cov yam ntxwv ntawm lub plab. Yog li, lub plab zom mov monogastric dais ib lub plab hauv plab. Hauv kev tawm tsam rau qhov no, polygastric digestive system bears lub plab plaub-compartment. Qhov tseeb, qhov no yog qhov sib txawv tseem ceeb ntawm cov ruminants thiab non-ruminants. Tsis tas li ntawd, lawv lub peev xwm zom cov cellulose kuj txawv ntawm ob hom kev zom zaub mov. Txawm hais tias monogastric digestive system tsis tuaj yeem zom cellulose kiag li, lub plab zom mov polygastric tuaj yeem zom cov cellulose tag nrho. Yog li, qhov no qhia txog qhov sib txawv ntawm monogastric thiab polygastric digestive system.
