It secretes juices containing enzymes that are capable of digesting all major types of food -- carbohydrates, fats and proteins. The pancreas is the first organ to begin digesting fats. It secretes pancreatic lipase, esterase and phospholipase, which break down chemically complex fats into simple, easy-to-absorb fats. Similarly, trypsin and carboxypolypeptidase break down proteins, and pancreatic amylase breaks down carbohydrates.
The stomach is an organ of the digestive system. The inner wall of the stomach contains small pores called gastric pits. These pits contain cells that secrete chemicals that digest food. The two main types of exocrine secretory cells of the stomach are parietal cells and chief cells.Parietal cells secrete hydrochloric acid and chief cells secrete digestive enzymes such as pepsin.These cells secrete their products when activated by signals from the body such as hormones and neurotransmitters.hief Cells. The other type of exocrine secretory cell in the stomach is the chief cell. Chief cells secrete digestive enzymes that cleave the proteins in food into smaller pieces. The main enzyme secreted by chief cells is pepsin. Pepsin is secreted as an inactive enzyme called pepsinogen.
