Hungry? Is your stomach making noises? Did you catch a whiff of fresh cut fruit, and now your mouth is watering?
Then your digestive system is primed and ready to go to work breaking down food into smaller molecules so nutrients can be easily absorbed. Here’s some food for thought:
The digestive system is complicated. It has multiple organs; both mechanical and chemical processes are in play; a full complement of enzyme/substrate reactions takes place; and water and nutrients are absorbed to keep cells functioning. Take a look at our free digestive system infographic to help students visualize the structures and functions of the system.
Do you need a three-dimensional manipulative model of the digestive system? Carolina offers an almost life-size model that includes all of the structures from the mouth to the rectum. If you want your students to have an in-depth look at the stomach, consider this stomach model that is dissectible into 2 parts to show internal and external anatomy.
The microscopic tissue structure of the organs within the digestive system are linked to their specific functions. Students can examine the various digestive system tissue types with tissue models, Carolina’s digestive system slide set, or an intestine tissues self-study slide set. For a hands-on investigation of chemical digestion and the role gastric and intestinal enzymes play, we offer a digestion lab kit in which students investigate the effects of pH, temperature, and enzyme concentration on food digestion.
Build on the unit
We have a free activity that breaks the digestion pathway and enzyme content into chunks, making it easier for students to review the biochemistry of the process. Includes an answer key:
Essential Question: What are the locations, enzymes, and functions of the glands and organs in the digestive system?
Objective: Review digestive system structure and function for test preparation.
