Daim duab 01: Lub Plawv Lub Plawv

Mitral valve thiab tricuspid valve tswj cov ntshav ntws los ntawm atria mus rau ventricles thaum aortic valve thiab pulmonary valve tswj cov ntshav ntws tawm ntawm lub ventricles. Lub plawv li qub yog nyias nyias. Lawv qhib thiab kaw kom raug.

Sphincter yog dab tsi?

Sphincter cov leeg yog cov leeg zoo li lub nplhaib nyob rau hauv cov kabmob hollow. Cov leeg no nyob ib puag ncig ntawm lub cev los yog qhov qhib. Sphincters tuaj yeem cog lus lossis so kom txaus. Ib tug sphincter nquag pab ntws mus rau hauv ib qho kev taw qhia los ntawm kev so thiab nquag tawm tsam ntws mus rau qhov tsis sib xws los ntawm kev cog lus. Nyob rau hauv peb lub qhov quav kwj dej, muaj cov leeg sphincter raws li lub qhov quav sphincter thiab sab nraud qhov quav sphincter txhawm rau tiv thaiv kom tsis txhob plam plob tsis so tswj. Kev puas tsuaj hauv cov leeg sphincter ua rau faecal incontinence. Lwm qhov sphincter tseem ceeb hauv peb lub cev yog sphincter pylori uas tuav cov zaub mov hauv plab kom txog thaum nws sib xyaw nrog cov kua txiv hmab txiv ntoo. Ntxiv mus, sphincter urethrae yog lwm qhov sphincter tseem ceeb uas tswj kev tso zis.
