Yog vim li cas cov dej ntws hauv mob ntsws Circuit Court txo ? lub xeev tawg ntawm lub ntsws menyuam hauv plab ua rau muaj kev tiv thaiv siab thiab ntshav siab hauv mob ntsws Circuit ces ntshav nyob rau hauv lub mob ntsws lub cev ntws dhau ntawm ductus rau hauv aorta qhov uas ntshav siab qis dua.
Ntawm no, yog vim li cas lub pulmonary ncig txo nyob rau hauv tib neeg fetus?
Nrog thawj qhov ua pa ntawm lub neej, lub ntsws pib nthuav dav. Raws li lub ntsws nthuav dav, alveoli hauv lub ntsws raug tshem tawm ntawm cov kua. Qhov nce ntawm tus menyuam cov ntshav siab thiab qhov loj txo hauv mob ntsws siab txo qhov xav tau rau ductus arteriosus kom tshem tawm cov ntshav. Cov kev hloov pauv no pab kaw qhov kaw.
Ib yam nkaus, yuav ua li cas menyuam hauv plab tso ntshav kom hla dhau lub ntsws quizlet? Lub sijhawm fetal kev loj hlob, lub foramen ovale tso cai ntshav kom dhau los ntawm sab xis atrium mus rau sab laug atrium, hla qhov tsis ua haujlwm menyuam hauv plab thaum lub fetus tau nws cov pa los ntawm lub tsho me nyuam. Yog li, nws tso cai cov pa ntshav los ntawm txoj hlab ntshav mus rau hla lub siab.
Tom qab, lo lus nug yog, dab tsi yog qhov pulmonary ncig txo nyob rau hauv lub cev xeeb tub tib neeg fetus?
Feem ntau ntawm cov ntshav uas tawm ntawm txoj hlab ntshav sab xis hauv fetus bypasses lub ntsws los ntawm qhov thib ob ntawm ob qho ntxiv fetal kev sib txuas hu ua ductus arteriosus. Lub ductus arteriosus xa cov ntshav tsis txaus oxygen mus rau cov kabmob hauv qis ib nrab ntawm fetal lub cev.
Dab tsi yog peb tus menyuam hauv plab tsis xav tau ntxiv thaum tus menyuam yug los thiab ua pa?
Sai li qhov menyuam yug los , lub foramen ovale, ductus arteriosus ductus venosus thiab umbilical hlab ntsha yog tsis xav tau lawm.

Qhov no txhais tau hais tias thaum lub voj voog ib zaug, cov ntshav mus ob zaug hauv plawv. Qhov kev faib ua ob zaug no tseem ceeb heev vim nws ua kom muaj cov pa oxygenated rau cov leeg thiab tsis sib xyaw ntawm cov pa oxygen thiab de-oxygenated ntshav. Yog li, qhov system no ua kom muaj txiaj ntsig zoo ntawm cov ntshav oxygenated rau cov leeg
