Location of Brunner’s Glands
Brunner's gland which produces alkaline secretions are present in:
- Submucosa of Duodenum — Correct Answer
- Submucosa of Jejunum
- Mucosa of Duodenum
- Submucosa of Ileum
Explanation:
Correct Answer: Submucosa of Duodenum
Brunner's glands are unique submucosal glands found exclusively in the submucosa of the duodenum. They secrete an alkaline, bicarbonate-rich mucus that neutralizes the acidic chyme (pH 2) arriving from the stomach, protecting the duodenal wall and creating an optimal pH for pancreatic enzyme activity.
Small Intestine — Digestive Roles
| Segment | Key Feature/Role |
|---|---|
| Duodenum | Brunner's glands (submucosa); receives bile and pancreatic juice; main site of protein absorption in non-ruminants |
| Jejunum | Main site of fat absorption (proximal jejunum); active nutrient absorption |
| Ileum | Protein absorption in ruminants; bile salt reabsorption |
Digestion Comparison — Ruminant vs Non-Ruminant
| Nutrient | Ruminant end product | Non-ruminant end product |
|---|---|---|
| Carbohydrate | VFAs (absorbed via ruminal wall) | Glucose (absorbed in small intestine) |
| Protein | Amino acids (absorbed in ileum) | Amino acids (absorbed in duodenum & jejunum) |
| Fat | Fatty acids (proximal jejunum) | Fatty acids (proximal jejunum) |
