Human Body & Health

Why does the body absorb more free fatty acids in the small intestine compared to the stomach, even though both organs experience peristalsis?

A)Gastric pH denatures more lipases
B)Bile emulsification increases surface area
C)Villi block absorption in stomach
D)Stomach peristalsis inhibits enzyme action

💡 Explanation

Bile emulsification increases surface area for lipase activity, leading to enhanced fatty acid absorption in the small intestine, because emulsification reduces fat globule size, increasing enzymatic access. Therefore, more absorption occurs in the small intestine, rather than the stomach, where emulsification is limited.
