Question

Dietary fat is predominately absorbed in what part of the gastrointestinal tract?

1: Ileum and colon
2: Stomach and duodenum
3: Distal jejunum and ileum
4: Duodenum and proximal jejunum

Answer 1

The majority of dietary fat is absorbed in the small intestine, with most absorption of carbohydrates and proteins occurring in the jejunum.

Step-by-step explanation:

Almost all ingested food, 80 percent of electrolytes, and 90 percent of water are absorbed in the small intestine. Although the entire small intestine is involved in the absorption of water and lipids, most absorption of carbohydrates and proteins occurs in the jejunum. Bile salts and vitamin B12 are absorbed in the terminal ileum.
