Hais txog qhov no, qhov twg yog cov kua txiv zom tau tsim?
Cov kua txiv zom tau tsim thoob plaws hauv cov hnyuv thiab hauv pancreas , thiab kua tsib yog tsim nyob rau hauv daim siab. Cov kua tsib thiab kua txiv pancreatic khoob rau hauv nruab nrab ntawm duodenum los ntawm sphincter ntawm Oddi. Kev zom zaub mov cuam tshuam nrog kev tawg los ntawm cov enzymes ntawm cov zaub mov molecules rau hauv lawv cov khoom yooj yim molecules.
Tsis tas li ntawd, cov kua txiv hmab txiv ntoo yog dab tsi? Digestive enzymes
| Digestive kua txiv thiab enzymes | Cov tshuaj zom | Cov khoom tsim |
|---|---|---|
| Gastric kua txiv Protease (pepsin) thiab hydrochloric acid | Cov protein | Ib nrab zom cov protein |
| Pancreatic kua txiv Proteases (trypsin) Lipases Amylase | Proteins Fats emulsified los ntawm cov kua tsib Starch | Peptides thiab amino acids Fatty acids thiab glycerol Maltose |
Qhov tseeb, cov kua txiv hmab txiv ntoo muaj dab tsi?
Rhuav tshem Gastric Juices Cov kua txiv hauv plab yog tsim los ntawm dej, electrolytes, hydrochloric acid, enzymes, mucus, thiab qhov tseem ceeb. Hydrochloric acid yog cov kua qaub uas zais los ntawm cov cell parietal, thiab nws txo qis koj lub plab pH mus rau ib puag ncig 2.
Cov qog dab tsi tsim cov kua txiv digestive?
Cov enzymes digestive yog secreted los ntawm cov qog exocrine sib txawv xws li:
- Cov qog salivary.
- Cov kab mob hauv plab hauv plab.
- Cov kab mob zais cia (islets) hauv cov txiav txiav.
- Cov qog secretory hauv cov hnyuv me.
