Digestive System

#4 Esophagus:It uses rhythmic muscle movements (peristalsis) to force food from the throat into the stomach.

#3 Pharynx:Commonly called the throat; recieves food from the mouth to swallow.

#1 Mouth:Food is broken down by chewing and by the chemical action of salivary enzymes.

#2 Salivary Glands:Produce saliva, that contains enzymes that break down carbohydrates into smaller malecules.

#5 Liver:It filters toxins from the blood, and makes bile (breaks down fats) and some blood proteins.

#6 Stomach:Both chemical and mechanical digestion takes place in the stomach. When the food enters the stomach, it is churned in a bath of acids and enzymes.

#7 Gall Bladder:It stores and releases bile (a digestive chemical which is produced in the liver) into the small intestine.

#11 Anus:The opening at the end of the digestive system from which waste exits the body.

#8 Pancreas:An enzyme-producing gland; enzymes from the pancreas help in the digestion of carbohydrates, fats, and proteins in the small intestine.

#10 Large Intestine:Some of the water and electrolytes (chemical like sodium) are removed from the food. Alot of the bacteria help in the digestion process. The first part is the cecum (appendix is connected to it). Food then travels upward in the ascending colon. Teh food travels across the abdomen in the transverse colon, goes back down the other side to the descending colon, and then through the sigmoid colon.

#9 Small Intestine:Food enters the duodenum, then moves down to the jejunum an dthen the ileum. In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and the other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.
