Your Digestive System and How It Works http://digestive.niddk.nih.gov/ddiseases/pubs/yrdd/
Topic: Digestion and digestive System
Introduction
system The digestive system is made up of the digestive tract—a series of hollow organs joined in a long, twisting tube from the mouth to the anus—and other organs that help the body break down and absorb food (see figure).
Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine—also called the colon—rectum, and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract.
Two “solid” digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver’s digestive juices until they are needed in the intestine. Parts of the nervous and circulatory systems also play major roles in the digestive.
Learning Tasks/ Learning Experiences
Activity
The students will view different video presentations regarding digestive system. After viewing the video presentations, they will then proceed to their respective group to have a small group discussion using the questions given to them. This will only be 5 minutes
After, doing the small group discussion, the information officer of the group will be called to give their opinion regarding the issues and concerns given to them through the guide questions. This will only be 3-5 minutes.
A group may compose of:
Madam Chair/ Young Master: serves as the leader and the lead discussant of the group.
Secretary: The one that will record the flow of the discussion.
Media man: The one that will deliver the information on what has been discussed.
The students will compose a song regarding the events of digestion and the structures and its functions of the digestive system. They will be presenting it in the class. Each group will be given 5-8 minutes to prepare their composition and 2 minutes presentation.
Analysis
There will be questions that will be given to the students before and after the video presentations, these questions will serve as their guide as they go along the way with their small group discussion.
Questions that will be given before viewing the video presentations
1. What are the structures and its functions involved in digestion?
2. What types of digestion that takes place in the mouth?
3. What are enzymes used to digest:
3.1 carbohydrates,
3.2 fats,
3.3 proteins?
4. Where does the digestion of;
4.1 carbohydrates
4.2 fats
4.3 proteins take place?
Question for the group
In one word, how could you describe digestive system in terms of; structures, functions in general and its importance?
Abstraction
For the students to really retain what are those insights that were given by the different group, the teacher will reiterate and condense all the ideas given by each group.
Application
In order to determine whether the students had able to attain the given objectives, the students will present their newly composed songs regarding the events in digestion and the structures involved.
There will also be sets of questionnaires and activity sheets that will be distributed to each of the group and each of the students.
Home Activity
The students will visit the blog created, Animal World. There are series of activities related to digestive system that are recently posted.
