What are local intermittent segmentation contractions in the gut wall?
What are local intermittent segmentation contractions in the gut wall?
- Constrictions that occur every few centimeters in the gut wall, lasting only 5 to 30 seconds (correct)
- Constrictions that last for minutes at a time
- Constrictions that occur only in the large intestine
- Constrictions that occur randomly and unpredictably throughout the gut wall
What is the purpose of peristaltic and constrictive movements in the gastrointestinal tract?
What is the purpose of peristaltic and constrictive movements in the gastrointestinal tract?
- To prevent the contents of the gut from moving
- To chop and shear the contents of the gut
- To propel the contents of the gut (correct)
- To mix the contents of the gut
How do peristaltic and constrictive movements differ in different parts of the gastrointestinal tract?
How do peristaltic and constrictive movements differ in different parts of the gastrointestinal tract?
- They are faster in the small intestine than in the large intestine
- They are modified for proper propulsion and mixing in different parts of the gastrointestinal tract (correct)
- They are the same throughout the entire tract
- They are slower in the small intestine than in the large intestine
