Mechanisms of Food Movement in GIT
View Complete Answer & Explanation
Question (English)
Food in the GIT is moved forward by:
- Peristalsis only
- Segmentation only
- Pendular movement only
- All of the above — Peristalsis, Segmentation, and Pendular movement ✓ Correct
Explanation:
Correct Answer: All of the above
Food movement through the gastrointestinal tract (GIT) involves three types of motility patterns:
Types of GIT Motility
| Type | Nature | Primary Role |
|---|---|---|
| Peristalsis | Progressive wave contractions moving aborally (mouth to anus) | Main propulsive force — moves food forward |
| Segmentation | Ring-like local contractions dividing intestinal contents into segments | Mixing (digestion and absorption) — some forward movement |
| Pendular movement | Back-and-forth swinging movements | Mixing of intestinal contents |
Mastication and Rumination
- Normal ruminal motility in cattle: 3 cycles per 2 minutes
- Regurgitation initiates in the reticulum (not rumen)
- Eructation: Elimination of rumen gases through mouth
