Why 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.
