Accessory Organs, Facilitate the Digestive System

Liver – largest Gland (accessory organs of the digestive system)

The liver is the largest gland in the body and is the accessory organs of the digestive system of this digestive system.

Food that is chewed in the oral cavity then consumed ends up in the gut where it is further digested so its nutrients can be absorbed in the small intestine. The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion perform key roles in the digestive procedure. Every one of these organs either secretes or stores chemicals that pass through ducts into the alimentary canal.

1. Saliva Moistens Food and Begins the Chemical Digestion Process

Six salivary glands, (accessory organs of the digestive system), located around the oral cavity, secrete saliva. This substance moves out of the glands to the oral cavity via ducts. Saliva is 99% water, but also contains enzymes and proteins that lubricate the nasal tissues and start chemical digestion of meals. There are 3 pairs of salivary glands (parotid, submandibular, and sublingual glands) and two ducts (Stensen’s and salivary ducts) on either side of the oral cavity.

2. The Liver Secretes Bile to Emulsify Fats from the Small Intestine

The liver (accessory organs of the digestive system) is one of the largest organs in the body and it is always producing bile. Bile flows from the liver to the left and right hepatic ducts. In the common hepatic ducts, and toward the small intestine to aid with digestion and the absorption of fats.

3. The Gall Bladder Stores Bile

If bile isn’t immediately necessary for digestion, then it flows up the cystic duct to the gall bladder. Long that stores and concentrates excessive bile secretion by the liver. Bile is released by the gall bladder as needed to the gut.

4. Pancreatic Juice Breaks Down Protein, Fats, and Carbohydrates

The pancreas (accessory organs of the digestive system) secretes pancreatic juice, a mix of digestive enzymes, water, buffers (bicarbonates), and electrolytes produced by acinar and pancreatic cells. Pancreatic juice drains throughout the major pancreatic duct (duct of Wirsung). That into the common bile duct and then into the small intestine. There it buffers stomach acids also breaks down protein, fats, and carbs.
