Mouth |
The beginning of the digestive tract, where mechanical digestion takes place |
|
Esophagus |
Located in your throat near your trachea (windpipe), this structure receives food from your mouth when you swallow. |
|
Peristalsis |
The involuntary constriction and relaxation of the muscles of the Esophagus, intestines and canals along the digestive tract, creating wave like movements that push the contents of the canal foward. |
|
Stomach |
When the contents of this structure are sufficiently processed, they are released into the small intestine. Cells in the lining of this structure secrete a strong acid and powerful enzymes that are responsible for the breakdown process. |
|
Liver |
Its main function within the digestive system is to process the nutrients absorbed from the small intestine. This structure detoxifies potentially harmful chemicals. It breaks down and secretes many drugs. |
|
Gallbladder |
Stores and concentrates bile, and then releases it into the duodenum to help absorb and digest fat
|
|
Pancreas |
Secretes digestive enzymes into the duodenum that break down protein, fats, and carbohydrates. It also makes insulin.
|
|
Large Intestines
|
Also known as the colon .Stool is first in a liquid state and made into a solid form because of the water removal
|
|
Small intestines |
Made up of the duodenum, jejunum, and ileum. Breaks down food using enzymes released by the pancreas and bile from the liver.

Celiac disease
|
Autoimmune disorder that can occur in genetically predisposed people where the ingestion of gluten leads to damage in the small intestine.
|
|
Colitis
|
digestive disease causing inflammation of the large intestines.No exact cause
|
|
Chemical digestion
|
uses certain enzymes to break down nutrients, such as carbohydrates, proteins, and fats, into smaller molecules
|
|
Mechanical Digestion
|
physically breaking down food substances into smaller particles to more efficiently
