 Bile salt from the gall  bladder  mix with  fats to further  break  them  down  in a process  called emulsification


Explanation

Emulsification  involve breakdown   of large  fat  globules into tiny droplet  in  the duodenum.  This provide  a large surface area  on  which  the enzyme  pancreatic lipase  can act to  digest  the fats  into  fatty   and  qlycerol. Emulsification  is assisted  by  action of bile salt  where  the secreted bile  in the liver  and stored  in the  gallbladder  is released  to the duodenum .
