Dr. William Beaumont discovered gastric acids in the 1820's and is known as the "Father of Gastric Physiology". He published his book "Experiments and Observations on the Gastric Juice, and the Physiology of Digestion" in 1838.

It takes the body about 2 1/4 hours to digest some types of lettuce, such as iceberg. Some quickly digesting foods that take only 1 3/4 hours are grapes, mangoes, raspberries, and avocados.

Stomach and small intestine are the two most important. The large intestine is pretty important too since it absorbs water and nutrients so that they don't get excreted. But they are all important.

The food would be stuck in your esophagus

It is called intestinal lining. Simple.

The Digestive System is vital to the human body becasue it breaks down all of the food we eat into molecules. These molecules can then be absorbed into the bloodstream eventually to be used by the cells. The digestive system is made up of many different organs, all of which help with the process of taking the nutrients out of the food we eat, and turning it into energy for our bodies cells. Once all the nutrients has been transfered into energy and stored into the cells of the body, the undigestable food is then passed through the anus as faeces.

so your body can absorb as much nutrients as it can from the food you eat.

The digestive system may be broken into two parts: a long, winding, muscular tube accompanied by accessory digestive organs and glands. That open-ended tube, known as the alimentary canal or digestive tract, is composed of various organs. These organs are, in order, the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The rectum and anus form the end of the large intestine. The accessory digestive organs and glands that help in the digestive process include the tongue, teeth, salivary glands, pancreas, liver, and gall bladder.

Saliva breaks down your food as you chew, softening it and making it smaller. It also lubricates the esophagus.

The mouth makes the food more chewed up so that it can go down easier through the esophagus. The chemical processes in the stomach work better when the food is chewed and able to soak up the stomach acid. The mouth also secretes enzymes in the saliva to help break down starches that are in the food.

What is a fatty substance found only in animal tissues

our teeth break down food physically which is called mechanical break down

The alimentary canal consists of the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. In adults, the alimentary canal is about 30 feet long.

Other names for the alimentary canal include the gastrointestinal (GI) tract, digestive tract, alimentary tract, and nourishment canal.

Starch is being digested.

The liver is the organ the makes the liquid bile. It helps digest fats and lipids.

Fibre is a carbohydrate that the body cannot break down.

It is very important for functionality of the digestive system and to control glucose absorption and other functions that we are learning about.

Fibre is in a form of soluble and insolubles. Both are needed and beneficial to our bodies

Chewing food takes from 5-30 seconds

Swallowing takes about 10 seconds

Food sloshing in the stomach can last 3-4 hours

It takes 3-6 hours for food to move through the small intestine

The remaining water in the food is sucked up by the large intestine can last 18-24 hours

The waste of the food is then stored in the colon, where they remain,

usually for a day or two, until the feces are expelled by a bowel

movement through the rectum.

I know that it takes about 8 hours to get through both the stomach and the small intestine. And most digestion occurs in the small intestine. So, probably about 2-3 hours. Remember, the stomach only has the enzyme to digest proteins, so why on earth would a lot of digestion occur in it?

It is a hormone which controls the quantity of pancreatic juice and bile in small intestine. It causes the release of digestive juices into the intestine by controlling sphincter of oddi (valve between ampulla of vater and small intestine). Ampulla of vater is formed by the union of common bile duct and pancreatic duct.
