Bile, produced by the liver acts as a surfactant to emulsify lipid or fat droplets.


Without too much technical detail, bile, emulsifies fats by aggregating around fat droplets and turning them into micelles which are slightly smaller droplets of fats. Bile prevent these micelles from coming together to form large fat droplets, thus maintaining a greater surface area (since size is inversely proportional to surface area) for pancreatic lipase (an enzyme) to act on the lipid droplets and digest it.
