Functions Of Liver In Digestive System – Did you know that digestion is a north-south process? It starts in your brain and ends in your ass. Digestion requires two main activities related to the mechanical and chemical breakdown of food: grinding food into the smallest possible particles so that the body can absorb nutrients easily and efficiently. These nutrients are critical to every function of your body and are used by every cell, organ and system for fuel and energy!
It is amazing that just the sight and smell of food awakens our salivary glands and causes them to start producing saliva. Saliva is essential for digestion because it contains water and solutes. Solutes are enzymes, in this case amylase, that help break down carbohydrates. All of this happens before we even finish chewing. When we say something is good for the mouth, that’s why!
Functions Of Liver In Digestive System
The mouth is the entrance to the digestive system through which all nutrients enter. Along with the physical action of chewing, chemical (enzymatic) breakdown of food occurs here, resulting in a bolus (a ball of chewed food).

When we swallow, the bolus enters the esophagus, preparing to pass into the stomach. It goes to a small valve called the cardiac sphincter. When the digestive system is in good working order, this little valve opens (and closes when needed) to allow the bolus to pass down into the stomach and prevent it from returning.
Once the bolus reaches the stomach, it mixes with gastric juice and becomes chyme (from the Greek khūmos “juice”). If digestion is working properly, the stomach secretes gastric juice from millions of tiny glands in the lining. Here, an optimally functioning digestive system will produce HCl (hydrochloric acid) and pepsin. Unfortunately, many of us are out of balance and do not have these important digestive secretions. Without adequate levels of acid in the stomach, chyme cannot be broken down until it enters the small intestine. Food remains in the stomach, where it can cause acid reflux, H. pylori, GERD, and other digestive problems.*
When the stomach completes its task of breaking down the bolus into chyme, it opens a valve at the bottom of the stomach, allowing the chyme to enter a chamber known as the duodenum. The duodenum is the first and shortest segment of the small intestine that receives chyme from the stomach and plays a vital role in the chemical digestion of chyme in preparation for absorption in the small intestine. It is in the duodenum that the highly acidic chyme is “cooled” and further broken down by bile and pancreatic juice. It is necessary for emulsification and absorption of fat.
Note. The liver, gallbladder and pancreas are called bile ducts. Food particles do not pass directly through the bile ducts. Instead, bile (produced in the liver and stored in the gallbladder) plus digestive juices, enzymes, and bicarbonates (produced by the pancreas) enter the digestive tract through ducts in the duodenum. In other words, while the liver, gallbladder, and pancreas do not “digest food,” they are critical to all digestion (as are the valves/sphincters).

The largest organ in the body, the liver performs over 500 functions, including producing bile and filtering toxins. Bile is a fluid that helps break down fat and remove toxins that the liver filters from the body. Bile also lubricates the intestines, preventing constipation. Without well-functioning bile, the body cannot properly absorb fats and the fat-soluble vitamins A, D, E, and K.
The gallbladder is a gland that stores bile produced by the liver. When fats are consumed, the gallbladder releases bile into the duodenum, where it mixes with pancreatic juice to break down the food into molecules that can be absorbed in the small intestine.
The pancreas is the gland that produces digestive juices, a mixture of bicarbonate and pancreatic enzymes that further digest fats, proteins, and carbohydrates. When bile from the gallbladder breaks down fat into specific microscopic particles, pancreatic digestive lipase enzymes can further break down fat for absorption in the small intestine. The pancreas produces insulin, which converts sugar into energy and stores excess sugar as fat. And the pancreas helps the digestive system by producing hormones. Pancreatic hormones help regulate blood sugar and appetite, stimulate stomach acidity, and tell the stomach when to empty it.
The small intestine is the part of the intestine where 90% of food is digested and absorbed. (The other 10% is found in the stomach and colon, in addition to accessory organs such as the liver, pancreas, and gallbladder.) The main function of the small intestine is the absorption of nutrients and minerals from food.
Organs And Function Of The Digestive System
The colon recycles water and waste that nourishes the colon cells. It captures the lost nutrients still present (with the help of gut microbes) and converts the nutrients into vitamins K, B1, B2, B12. Then butyric acid is produced and it’s time to go to the bathroom! Size of this preview: 720 × 600 pixels. Other resolutions: 288 × 240 pixels | 576×480 pixels | 922×768 pixels | 1200 × 1000 pixels.
English: The image differs from the original in that the small intestine is divided into the duodenum, jejunum, and ileum, and a closed epiglottis is added. Like no other illustration I know of, it offers the idea that the duodenum and jejunum are short sections of the small intestine, and the ileum makes up the bulk of the small intestine. You may be interested to know that the digestion of food, i.e. proteins, carbohydrates and fats, is completed before the leading edge of the food reaches the ileum. In the case of proteins and carbohydrates, this is because the duodenum and jejunum are “loaded” with membrane-bound enzymes and additional active transporters necessary for efficient absorption of the amino acids and monosaccharides that are produced by the enzymes. This is also due to the fact that the pancreas “dumps” a rich supply of soluble enzymes into the duodenum when food enters the duodenum. This is also due to the fact that the physical chemistry of the environment in the small intestine is controlled so that the enzymes can be most active. Fat digestion is different, but fat (triglycerides and phospholipids) is also removed from the small intestine before it reaches the ileum. The ileum functions to absorb nutrients that are not actively transported into the body. The absorption of most drugs depends on the ilium. In many cases, absorption continues after the substance has passed into the colon.

It breaks down food into chemicals that can be absorbed into the bloodstream. From the bloodstream, nutrients enter the liver, which is a kind of chemical factory for the body. The liver adjusts the nutrients so that the mixture meets the needs of the body.
Gastric acid is injected into the stomach. Basically, it’s dilute hydrochloric acid. It is highly reactive and has a pH level of 1.5 to 3.5.

The digestive system also gets rid of waste. The gastrointestinal tract begins with the lips and ends with the anus. Animals such as worms, insects, mammals, birds, fish, and humans all have a digestive system.
The digestive system is not only the intestines, but also other organs that help us digest food. For example, digestive enzymes are needed to break down carbohydrates and meat into digestible substances.
Food does not pass through these organs. But they help the intestines digest food. They have other things to do. For example, the pancreas, thyroid, liver, and parathyroid glands are also endocrine glands that produce hormones such as insulin.
There are a lot of diseases that affect the gastrointestinal tract. Doctors who study the gastrointestinal tract are called gastroenterologists.
