Lesson Plan: The Digestive System Biology
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the major components of the digestive system and their adaptations.
Objectives
Students will be able to
- describe the digestive system as an organ system where different organs work together to digest food,
- identify the main organs within the human digestive system,
- describe the adaptations of the digestive system, including the role of villi in the small intestines, the role of hydrochloric acid in the stomach, the purpose of bile, and the purpose of enzymes released by the pancreas and the small intestine,
- recall that food that cannot be digested is removed as feces from the body,
- describe how digested nutrients are absorbed into the transport systems of the body.
Prerequisites
Students should already be familiar with
- the fact that energy for key processes is obtained from food,
- the fact that the human body is comprised of organs and organ systems.
Exclusions
Students will not cover
