What do all the organs in the digestive system do and explain them in detail. 20 POINTS

The main function of the digestive system is to break down food into simple chemicals that can be easily absorbed by the body. Basically, all the organs in the digestive system break down food to absorb it's nutrients. The organs that make up the alimentary canal, or gastrointestinal tract, which are the mouth, esophagus, stomach, small intestine, and large intestine. The mouth chews food to mash it into a substance which the esophagus carries into the stomach, which mashes and churns the food with enzymes and acids. Then, the stomach contents are transported into the small intestine, where they are broken down and then absorbed into the bloodstream by villi, which are fingerlike objects. Then, food is transported into the large intestine, where the colon absorbs extra water in the food and then it is transported into the rectum and removed from the body as solid waste, which is what happens when you use the restroom. Although the liver, pancreas, and gallbladder are not part of the alimentary canal, they still help with digestion. The liver creates bile, which is a yellow liquid used to break down fats, and is stored in the gallbladder and is released into food. The pancreas releases enzymes in the small intestine to digest food and creates hormones like insulin.

Sorry if my answer was too long.

Digestion is the process of breaking down chemicals from food into forms that the body can use!

The process of digestion begins in your mouth. When you chew and break up your food with your teeth, this is known as physical digestion. Chemical digestion is the process of chemically breaking down the food/nutrients with enzymes, which is a chemical that speeds up the process of digestion. Enzymes in the saliva (which is produced by the salivary glands) break down the carbohydrates in the food into sugars. The saliva also moistens and softens the food which makes it easier to swallow. The tongue moves the food around and rolls it up into a soft ball that's swallowed and then travelling down a muscular tube called the esophagus.

The esophagus transports food to your stomach through a process called peristalsis.

The stomach is muscular pouch that stretches when full and folds up when empty.  Glands in the stomach release hydrochloric acid that kills many harmful organisms in the food and also begin breaking down proteins. Some other glands make and release enzymes that also help digest the proteins. The walls of the stomach contract and relax to mix the food with the enzymes. The stomach lining is covered with mucus, so the hydrochloric acid doesn't eat up your stomach. After your stomach is finished digesting after several hours, it becomes a pasty-mixture called chyme. The stomach squeezes a bit of the mixture into a long tube called the small intestine.

The small intestine has glands in the walls of it that continue the breakdown of carbohydrates and proteins. A different organ, the pancreas, releases enzymes into the small intestine that help speed up the process.  The liver makes bile (a fluid that breaks fats into small droplets) which can be digested. The gall bladder is practically a storage unit for the bile. When digestion is completed in the small intestine, the food materials are in thin, liquid forms that can be absorbed through the bloodstream.

Food that is not absorbed through the small intestine goes into a wide tube called the large intestine that contains bacteria. The bacteria breaks down plant fibers into glucose. Vitamins, minerals,  and water from digestive fluids are absorbed by blood vessels in the large intestines' walls.

The remaining, unabsorbed materials are in the form of solid waste, and then the large intestine passes the wastes out of the body through the anus.

Primary Organs (Food goes through these): Mouth, esophagus, stomach, small intestine, large intestine, and anus.

Accessory Organs (Food doesn't go through these): Salivary glands, liver, gall bladder, and pancreas.
