Miscarile la nivelul intestinului subtire sunt contractii de amestec si contractii propulsive. Contractile de amestec fragmenteaza chimul determinand amestecarea progresiva a particulelor alimentare solide cu secretiile din intestinul subtire. Frecventa de fragmentare este:
-
9-10 ori pe minut
-
6-8 ori pe minut
-
8-12 ori pe minut
-
5 pe minut
That's Correct!
It's Wrong!
The correct answer is "8-12 ori pe minut". The explanation is that the movements in the small intestine consist of mixing contractions and propulsive contractions. Mixing contractions fragment the chyme, allowing for progressive mixing of solid food particles with secretions in the small intestine. The frequency of these contractions is 8-12 times per minute.
