What are the three accessory organs of the digestive system?

Explanation

Solution

The gastrointestinal tract, as well as the digestive organs that support it, make up the human digestive system. From the mouth to the anus, the GI tract is made up of a succession of hollow organs connected by a long, twisting tube. Food is broken down into smaller and smaller components during digestion until it can be absorbed and incorporated into the body.

Complete answer:
The mouth cavity, throat, oesophagus, stomach, small intestine, and large intestine make up the gastrointestinal system. The teeth, tongue and glandular organs such as the salivary glands, liver, and pancreas are accessory organs.
Saliva is produced by the salivary glands, and it keeps the mouth and other areas of the digestive system wet. It also aids in the digestion of carbohydrates (through salivary amylase, formerly known as ptyalin) and lubricates food transit from the oro-pharynx to the oesophagus and stomach.
The liver is the biggest gland and internal organ in the human body. It has a variety of purposes, but as an auxiliary organ of the digestive system, it generates bile, which emulsifies fats and other lipids for better digestion. The gallbladder stores bile generated by the liver. When fat-containing food is present, the gallbladder contracts and releases bile into the duodenum.
The pancreas' exocrine glands produce a variety of enzyme precursors and enzymes, including trypsinogen, chymotrypsinogen, and procarboxypeptidase, which are activated by enteropeptidase in the small intestine; active alpha-amylase; lipases and colipase, which act on triglycerides and phospholipids. Some other enzymes in pancreatic juice are ribonuclease, elastase and collagenase.

Note:
Digestive glands are generally exocrine in nature. Enzymes, ions, water, mucins, and other chemicals are secreted into the digestive system via exocrine glands. The glands can be found inside or outside the gastrointestinal system, in the walls of the stomach and intestines (salivary glands, pancreas, liver). Nerves and hormones are in charge of secretion.
