So, there you are, sitting at lunch, enjoying some grilled chicken pizza and a few orange wedges. When you’re finished, you take a last drink of milk, wipe your mouth, and head to your next class. In a few minutes you're thinking about the capital of Oregon or your science fair project. You've completely forgotten about that pizza lunch you just ate. But it's still in your stomach – sort of like a science experiment that happens all the time!
Your digestive system started working even before you took the first bite of your pizza. And the digestive system will be busy at work on your chewed-up lunch for the next few hours - or sometimes days - depending upon what you've eaten. This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat. So, let's find out what's happening!

Goals
During this module, you will:
- Discover what organs makeup the digestive system
- Identify the functions performed by those organs
- Demonstrate an understanding of what happens as a bite of food is digested
Outcomes
After completing this module, you will be able to:
- Identify the specific parts of the organs within the digestive system.
- Explain the movement of food through the digestive tract.
- Organize the parts of the digestive system in order.
- Explain the structures and functions within the digestive system.
- Demonstrate an understanding that regulation of an organism’s internal environment involves sensing the internal environment and changing physiological activities to keep conditions within the range required to survive.
