How it worksThe digestive system

is a long and intricate process. It starts in when the food goes into the mouth, down the esophagus, in the stomach, through your small intestines, around your large intestines, and back out the rectum.

Each step plays an important role in digesting the food and gathering nutrients.

The BeginningThe Mouth & Esophagus

The mouth is where food is taken in.

The saliva and teeth work together to begin to break down the food for the stomach to digest.

Each type of tooth in the mouth has a different job

After the mouth has properly began the digestion process, the food then travels down the esophagus to the stomach.

The muscles in the esophagus systematically squeeze the food down the esophagus

In The FireThe Stomach

It is a hollow muscular J-shaped organ

Holds food for 3-4 hours When the food is brought into the

stomach it then releases gastric acid called HCL (Hydrochloric Acid)

Has 3 parts: Fundus, Body, and Pylorus

ProcessorThe Small Intestine

This is where the food gets absorbed into the blood stream

The food travels through the duodenum to get from the stomach to the small intestine

The small intestine is nearly 20 feet long

The Final StepThe Large Intestine

This is where all the fluids are absorbed and the wastes are made into solids

The large intestine is nearly 5 feet long and travels around the outside of the small intestine

The large intestine has 3 parts: The transverse colon, the ascending colon, and the descending colon

HelpersPancreas and the Gallbladder

The pancreas is located behind the stomach.

It helps the body digest the food.

The pancreas also produces insulin

It is a small hollow sac that is attached to the bottom of the liver.

It releases any bile in the liver into the small intestine to help digest a fatty meal.

More HelpersAppendix and Liver

The appendix’s functions are not know.

Scientists think it used to be used more often when human ate more raw meats

The liver is the largest gland in the body.

It also helps to control the amount of proteins and sugars in the body by changing and storing excess amounts.
