Digestive System

Digestive System

The digestive system is a group of organs working together that takes food into the body which breaks food down and convert the food into energy into basic nutrients to feed the entire body.

How does it work?

Food enters through the mouth and then your salivary glands produce enough digestive juice to break down chemically. After that It will travel through the esophagus and into the stomach. Gastric juice in the stomach starts protein digestion. After some time (1-2 hours) for the food to break down into a thick liquid, the liquid will go through a pyloric value and into the first section of the small intestine. In your small intestine, digestion continues as the liquid mixes with variety of digestive juices from your pancreas, liver, and gallbladder. In the second section of the small intestine, it's further broken down into smaller molecules of nutrients that can be absorbed. Then it will move into the longest section of the small intestine, where all the remaining nutrients are absorbed through the lining of the ileum's wall.

As the remaining part passes through the colon, nearly all of the water is absorbed. Muscles in the wall of your colon separate the waste into small segments that are pushed into your lower colon and rectum.

How does the Digestive system relates to other systems in the body?

  • The Nervous system controls the Digestive system by stimulating it to digest.
  • The Circulatory system maintains constant blood flow to the digestive system.
  • The small intestine absorbs all the nutrients that digestive system produces.
  • The large intestine absorbs water from the food, then the waste food leaves the body.

Medication Problems

Constipation- The nerve and the muscle activity in the large intestine, resulting in the slow and difficult passage of stool

Peptic Ulcers- By disrupting a protective layer of mucus, that bacterium causes ulcers, which are sores in the lining of the stomach or first stretch of the small intestine.

Lactose Intolerance- Lack of enzyme that needs to digest the main sugar in milk. These usually happens 30 minutes to two hours after eating or drinking a dairy product.

Gastroesophageal reflux disease- A band of muscle at the end of your esophagus does not close properly. This allows stomach contents to leak back, or reflux, into the esophagus and irritate it.

How can we improve our lifestyle habits to prevent these health-related problems?

  1. A balanced diet
  2. Stay hydrated
  3. Manage stress

Interesting Facts

  • The average male will eat about 50 tons of food during his lifetime in order to sustain a weight of 150 pounds.
  • It takes your mouth, esophagus, stomach, small intestine, large intestine, gallbladder, pancreas and liver just to digest a glass of milk..
  • 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
  • The small intestine is about 22 feet long
  • The liver is the largest organ in the body and performs more than 500 functions.
