QUESTION 15

  1. Put the steps in the processes of fat digestion and absorption in order

    Chylomicrons are expelled into the interstitial fluid on the basal side of the jejunal epithelium, and then pass into the lacteals.Triglycerides are resynthesized inside of jejunal epithelial cells, and are packaged into chylomicrons.Mechanical digestion in the stomach breaks up injested food into smaller pieces. Large globules of injested fat entering the duodenum are emulsified by bile salts.The ester linkages in triglycerides found within micelles are broken down by pancreatic lipases to produce fatty acids.Fatty acids diffuse into jejunal epithelial cells.
