Describe the pathway that food takes through the digestive system (starting with mouth and ending with excretion out of the body).

Digestive system:
·     The mouth-the start of digestion, where the food is chewing and breaking ·     The pharynx- receives the food from the mouth
·     The esophagus- a muscular structure which carries food to the stomach via contractions
·     The stomach- sac-like organ which serves as the mixer and grinder of food, secretes acids and enzymes
·     Small intestine (the duodenum, jejunum, and ileum)-here, the food is broken down using enzymes released by the pancreas and bile from the liver ·     Large intestine (the colon, rectum, and anus)- for processing and excretion of waste.
