Digestive System Function Facts

We eat about 500kg of food per year. 1.7 liters of saliva is produced each day.

The esophagus is approximately 25cm long. Muscles contract in waves to move the food down the esophagus. This means that food would get to a person's stomach, even if they were standing on their head.

An adults stomach can hold approximately 1.5 liters of material.

Every day 11.5 liters of digested food, liquids and digestive juices flow through the digestive system, but only 100mls is lost in faces.

In the mouth, food is either cooled or warmed to a more suitable temperature.

Hundreds of different kinds of enzymes are needed to properly digest food. Cooking destroys food enzymes, forcing the body to make its own. Over time the body may tire of this extra work, leaving room for possible indigestion.

STOMACH: secretes some enzymes and hydrochloric acid (HCL) to break down protein. Within 2-6 hours, all food is emptied into the small intestine.

SMALL INTESTINE: over 90 percent of digestion and absorption takes place in the small intestine. The acid of the stomach is neutralized and food is mixed with enzymes, bile and pancreatic juices.

LIVER: aids in digestion and detoxification of food impurities and inspects nutrients before allowing them into the bloodstream.

GALL BLADDER: stores bile used to break down dietary fat.

PANCREAS: produces digestive juices and helps control blood sugar.

Digestive problems cost Americans $50 billion each year in both direct costs and absence from work.

70-year-olds may produce as little as half the enzymes they produced when they were 20.

By age 50, many people will produce only 15% of the HCL they released at age 25, and about a third of all people over the age of 65 secrete Digestive System1. For every 2 weeks, the human stomach produces a new layer of mucous lining, otherwise the stomach will digest itself.

4. The Liver is the only organ of the body, which has the capacity to regenerate itself completely even after being removed almost completely.

5. Liver cells take several years to replace themselves.

6. A healthy liver processes 720 liters of blood per day.

7. The human stomach contains about 35 million small digestive glands.

8. The human stomach produces about 2.5 liters of gastric juice everyday.

9. In an average person, it takes 8 seconds for food to travel down the food pipe, 3-5 hours in small intestine and 3-4 days in the large intestine.
