Bile and pancreatic juice enter the duodenum
A photomicrograph of the endocrine and exocrine portions of the pancreas
An illustration depicting the exocrine pancreatic acini, where the acinar cells produce inactive enzymes stored in zymogen granules
The activation of pancreatic juice enzymes
Intestinal hormones stimulate secretion of pancreatic juice and bile Food Molecules are digested by hydrolysis reactions and absorbed Carbohydrates are digested into monosaccharides Proteins are digested into amino acids Triglycerides are transported by the lymphatic system
The action of pancreatic amylase
The digestion and absorption of proteins
The digestion of triglycerides Pancreatic lipase digests fat (triglycerides) by cleaving off the first and third fatty acids This produces free fatty acids and monoglycerides
Fat digestion and emulsification
The hypothalamus regulates hunger and metabolic rate 1.Basal metabolic rate (BMR) 2.Adaptive thermogenesis 3.Physical activity
The absorption of fat
