← Human Body & HealthWhy does the ileum, rather than the stomach, primarily absorb digested fats despite both being part of the digestive system?
A)Stomach acidity degrades fat transporters
B)Bile emulsification precedes ileum absorption✓
C)Stomach lacks adequate surface area
D)Ileum peristalsis prevents fat aggregation
💡 Explanation
Bile emulsifies fats in the duodenum, preparing them for absorption in the ileum; therefore, efficient fat absorption occurs there, because bile-facilitated absorption requires prior processing. The stomach's primary role is mechanical and chemical breakdown rather than absorption, rather than immediate fat uptake.
