Lysozyme is another salivary enzyme, which helps to keep the mouth free from germs. Saliva also contains mucus, which coats the food and enables each bite to travel smoothly through the digestive tract. Share on Facebook
5 Organs That Secrete Digestive Juices
BY CHIDAMBARAM SUNDER VALLIAPPAN • AUG. 14, 2017
The five major organs that secrete digestive juices are the salivary glands, stomach, pancreas, liver and small intestine. Each of these organs synthesizes its mixture of digestive juices that breaks down food into smaller pieces that can be absorbed into the body.
Salivary Glands
The main salivary glands are found in the cheeks, under the tongue and around the jaw. They secrete about 1 quart of saliva each day. Amylase, also called ptyalin, is an enzyme in saliva that breaks down starches or complex carbohydrates -- such as bread, rice and potatoes. Lysozyme is another salivary enzyme, which helps to keep the mouth free from germs. Saliva also contains mucus, which coats the food and enables each bite to travel smoothly through the digestive tract.
Stomach
The stomach produces gastric juice which is comprised of HCl, water and enzymes. HCl works with the main gastric enzyme called pepsin to aid the digestion of protein-rich foods like eggs, meat etc. The production of acid is increased by a hormone known as gastrin, which is made by specific cells lining the stomach. The stomach also produces gastric lipase, which assists in digesting fats. Intrinsic factor, an enzyme-like compound which helps the small intestine absorb vitamin B12, is also produced in the stomach by oxyntic cells.Pancreas secrete proenzymes and pancreatic amylase.Liver secretes bile which helps in emulsification of fats.bile has no enzymes.Small intestine helps in breakdown of food into simplest components amino acids, monosaccharides fatty acids.
