In the stomach during the fed state, the primary type of contraction is/are _____________ and is responsible for ____________. Question 7 options: Tonic contractions; moving chyme forward Migrating myoelectrical complexes; moving chyme forward Peristalsis; retropulsion Segmentation; mixing chyme Segmentation; moving chyme forward Migrating myoelectrical complexes; mixing chyme

• Segmentation; mixing chyme

Explanation:

In the fed state, the small intestine exhibits two main contractile patterns which are mixing and propulsion. During mixing, the contractions are described as segmentation and which repeatedly divide the intestinal loops into equal divisions and allows the movement of contents inside the intestines to both directions. These contractions are therefore important because they separate and churn the chyme to ensure maximum digestion and absorption of nutrients.
