Qhov Tseem Ceeb Qhov Sib Txawv - Kev zom hauv tib neeg vs Ruminants
Kev zom zaub mov hauv cov tsiaj yog ib qho tseem ceeb hauv cov ntsiab lus ntawm kev zom cov zaub mov noj rau hauv cov ntaub ntawv yooj yim uas tuaj yeem nqus tau yooj yim los ntawm lub cev hlwb. Qhov no muab tag nrho cov ntsiab lus tseem ceeb uas xav tau los ntawm lub cev rau lub neej thiab kev loj hlob ntawm cov kab mob nyob. Cov txheej txheem digestive sib txawv tau hloov zuj zus raws li ntau hom, lawv cov qauv pub, thiab lawv qhov chaw nyob. Ruminant hom ciaj sia tsuas yog ntawm cov nroj tsuag. Lawv yog cov tsiaj txhu. Yog li ntawd, lub digestive system ntawm ruminants yog evolved nrog lub xub ntiag ntawm ib tug rumen uas yog ib tug complex plab nrog plaub sib txawv compartments. Tib neeg yog omnivorous uas nyob ntawm cov nroj tsuag thiab tsiaj txhu, yog li, lawv lub plab zom mov tsim ntawm ib lub plab. Qhov no yog qhov sib txawv tseem ceeb ntawm kev zom ntawm tib neeg thiab ruminants.
Kev digestion yog dab tsi?
Tib neeg yog omnivorous hom uas nyob ntawm cov tsiaj thiab cov nroj tsuag. Lawv lub plab zom mov txawv ntawm lwm hom. Tib neeg tsis muaj enzyme cellulase. Yog li ntawd, lawv tsis tuaj yeem zom cov teeb meem cellulosic. Tib neeg digestive ib ntsuj av kuj hu ua gastrointestinal ib ntsuj av. Nws yog tsim los ntawm cov qog ua ke sib txawv uas suav nrog lub siab, lub gallbladder, pancreas, qog nqaij hlav thiab tus nplaig. Tib neeg lub plab zom mov yog tsim los ntawm lub qhov ncauj thiab lub plab kab noj hniav, txoj hlab pas, plab, plab hnyuv, plab hnyuv loj, qhov quav, thiab qhov quav.
Mechanical digestion ntawm cov zaub mov tshwm sim nyob rau hauv lub buccal kab noj hniav. Cov qaub ncaug yog zais los ntawm cov qog qaub ncaug thiab sib xyaw nrog cov khoom noj. Nrog kev pab ntawm tus nplaig, cov khoom noj khoom haus tau hloov pauv mus rau hauv cov kua liquefied bolus kom yooj yim nqos. Kev zom cov zaub mov kuj tseem pib ntawm cov kab noj hniav vim tias qaub ncaug muaj salivary amylase. Hauv lub plab, cov enzymes sib txawv ntawm cov txiav thiab cov qog nqaij hlav raug tso tawm thiab cov zaub mov noj tau txais cov tshuaj lom neeg digested.
Daim duab 01: Tib neeg digestion
Cov hnyuv me yog lined yog tsim nrog thaj chaw siab dua rau kev nqus cov as-ham. Feem ntau ntawm cov as-ham yog absorbed nyob rau hauv cov hnyuv me mus rau hauv cov hlab ntsha. Dej feem ntau absorbed los ntawm txoj hnyuv loj. Cov khoom noj uas tsis tau digested raug tshem tawm ntawm lub cev los ntawm lub qhov quav uas cov khoom khaws cia nyob rau hauv lub qhov quav ib ntus.
Ruminant's Digestion yog dab tsi?
Tsiaj txhu xws li nyuj, yaj, thiab tshis suav hais tias yog hom tsiaj ruminant. Ruminant hom tuaj nyob rau hauv qeb, herbivorous tsiaj. Lawv tsuas yog nyob ntawm cov nroj tsuag. Herbivores, suav nrog cov ruminants, muaj cov kab mob ntau dua uas muaj cellulose enzyme zom cov cellulosic tebchaw hauv cov nroj tsuag. Ruminant hom muaj ib tug complex digestive system thaum piv nrog tib neeg. Lawv raug hu ua ruminant hom vim muaj cov rumen. Lub rumen yog lub plab nyuaj uas muaj plaub qhov sib txawv uas suav nrog Rumen, Reticulum, Omasum, thiab Abomasum. Tag nrho plaub qhov chaw sib txawv rau ib leeg hauv cov qauv thiab cov haujlwm uas lawv ua. Tawm ntawm plaub qhov chaw, rumen yog qhov loj tshaj plaws thiab muaj cov neeg coob dua ntawm cov kab mob uas muaj enzyme cellulose thiab ua rau muaj kev sib txawv fermentative.
Lub plab zom mov ruminant pib los ntawm qhov ncauj thiab kab noj hniav. Nws muaj 32 cov hniav uas koom nrog kev zom zaub mov ntawm kev noj cov nroj tsuag rau hauv cov kua qaub uas tov nrog qaub ncaug kom nqos tau yooj yim. Ib nrab chewed bolus pib nkag mus rau hauv rumen thiab undergoes fermentation rau lub sij hawm luv luv. Thaum tus tsiaj nyob so, nws muaj peev xwm hnoos tau qee qhov chewed zaub mov rov qab rau hauv kab noj hniav thiab zom nws tag nrho los ntawm lwm cov khoom noj. Qhov no yog qhia mus rau lwm lub compartments. Nyob rau hauv reticulum thiab abomasum, enzymatic digestion tshwm sim thiab cov as-ham uas yog digested, yog absorbed nyob rau hauv cov hnyuv. Nyob rau hauv omasum, dej thiab minerals uas muaj nyob rau hauv lub bolus yog absorbed rau hauv cov hlab ntsha. Cov abomasum thiab cov hnyuv me zoo ib yam li tib neeg. Cov zaub mov undigested bolus ces nkag mus rau hauv lub qhov quav thiab tawm hauv lub cev raws li fecal teeb meem. Herbivore fecal teeb meem tshwm hauv cov xim ntsuab thiab muaj cov feem pua ntawm cov dej ntau dua.
Dab tsi yog qhov zoo sib xws ntawm kev zom zaub mov hauv tib neeg thiab tsiaj txhu?
- Ob leeg koom nrog kev zom zaub mov noj.
- Mechanical digestion nyob rau hauv ob hom tshwm sim nyob rau hauv lub buccal kab noj hniav.

Summary – Kev zom hauv tib neeg vs Ruminants
Txiv tsiaj muaj ntau hom kev zom zaub mov. Cov txheej txheem digestive sib txawv tau hloov zuj zus raws li ntau hom, lawv cov qauv pub, thiab lawv qhov chaw nyob. Ruminant hom ciaj sia tsuas yog ntawm cov nroj tsuag. Lawv yog cov tsiaj txhu. Yog li ntawd, lawv lub plab zom mov yog hloov zuj zus nrog lub xub ntiag ntawm rumen uas yog lub plab nyuaj nrog plaub qhov sib txawv. Tib neeg yog omnivorous uas nyob ntawm cov nroj tsuag thiab tsiaj txhu. Lawv digestive system tsim los ntawm ib lub plab. Hauv ob qho tib si, cov khoom noj khoom haus tsis raug tshem tawm raug tshem tawm raws li qhov quav. Qhov no yog qhov txawv ntawm kev zom ntawm tib neeg thiab ruminants.
