Components of the GI tract
Mouth
Esophagus
Stomach
Liver
Pancreas
Gallbladder
Spleen
Aorta
Bladder
Uterus
Illiac Arteries
The Mouth
Located in the head
Mechanically breaks down food and begins the chemical breakdown of food with saliva
The Esophagus
Located substernal in the epigastric region
Moves food from the mouth to the stomach
The Stomach
Located in the left upper quadrant and the epigastric region of the abdomen
Mechanically and chemically breaks down food and turns it into chyme
The Liver
Located in the upper right and center of the abdomen
Produces bile; assists with carbohydrate, protein, and fat metabolism; stores vitamins/manufactures vitamins; detoxifies blood; eliminates waste
The Pancreas
Located posterior to the stomach
Produces enzymes for protein, carbohydrate, and fat breakdown within the duodenum but also produces insulin, somatostatin, and glucagon
The Gallbladder
Located on the inferior surface of the liver
Stores bile
The Spleen
Located in the left upper abdomen
Filters blood and recycles dead red blood cells
The Aorta
Located in the central upper abdomen
The main artery supplying blood to the lower body
The Bladder
Located in the suprapubic area
Stores urine
The Uterus
Located in the suprapubic area
Part of the reproductive system
The Illiac Arteries
Located in the central abdomen and lower right and left quadrants
Supplies blood to the lower legs
The Duodenum
Located in the central umbilical region
Site for chemical breakdown of food; site for water, fat, protein, carbohydrate, and vitamin absorption
