The digestive system breaks down food and extracts nutrients and energy. It begins with the mouth, where food is chewed and enzymes begin breaking it down. The esophagus then transports the food to the stomach through peristalsis. The stomach further breaks down the food before sending it to the small intestine for additional digestion and absorption of nutrients. Other organs like the liver, pancreas, and gallbladder produce enzymes and bile to help with digestion. The rectum stores waste before it exits through the anus.

1. Diorella Rosario 8-17 Digestive System

2. Introduction Breaking down food into smaller particles Breaks it down into digestive juices Without it we can’t get rid of waste Can’t produce energy to build and nourish cells without this system

3. Mouth Where the system starts Turns food mushy Breaks it down with chewing and uses enzymes in our body

4. Esophagus Connects the mouth to the stomach Moves through by peristalsis Peristalsis is a series of muscle contractions that move down

5. Stomach Provides basics of early digestion ex. holding meals for a long time Where the food is liquefied Once it’s liquefied it moves down to the small intestine

6. Liver Produces sugar from fatty substances Stores specific vitamins and processes fat Filters out toxic wastes in your body

7. Pancreas Makes hormones called insulin and glucagon Insulin helps regulate the blood glucose level An organ including enzymes that make cells

8. Gallbladder A small pouch in your body Produces bile which helps to digest fats in the foods you eat Releases it into the duodenum to help absorb fats

9. Rectum Only 5 cm long Where the feces is stored right before excretion Connects to the anus
