Torso Digestive System Lab

Torso Digestive Lab Objectives:

• Disassemble and reassemble the torso • Identify the major organs of the digestive tract • Identify the cavities and locations where the organs for the digestive tract are. • Discuss the functions of the organs of the digestive system

Materials:

• Mini torso • Labeling tape • Dissecting probe • Camera to take pictures of the organs both assembled and dissassembled

Instructions: Using the labeling tape, write the following on individual pieces: stomach oral cavity small intestine esophagus salivary glands duodenum tongue large intestine jejuneum pharynx appendix ilium pancreas abdominal cavity rectum liver cardiac sphincter gall bladder pyloric sphincter

Find a diagram of the internal organs in your anatomy textbook. Carefully point out the major organs visible without taking the model apart. Use the dissecting probe to accomplish this task, NOT YOUR PEN. Carefully disassemble the model starting at the most superior point. Remove the organs and place the labels on the appropriate organ or in the cavity. Please note where the organs came from as you will have to put the organs back in the cavities when you are finished. Have instructor check your work when you are finished. Remove labels and reassemble the model.

Questions 1) What are the types of digestion occurring in the oral cavity?

2) What is the process the esophagus uses to move food from the oral cavity to the stomach?

3) What prevents food from leaving the stomach and reentering the esophagus?

4) What is the function of the rugae in the stomach?

5) What are the three parts of the small intestine?

6) What is the function of the villi and microvilli in the small intestine?

7) What is the function of the liver?

8) What is the function of the gall bladder?

9) What are some major functions of the small intestine?

10) What does the pancreas secrete?

11) What is the primary function of the large intestine?

12) What is the function of the rectum? There are three basic food types, carbohydrates, proteins, lipids

A) What organ does carbohydrate digestion start? B) What organ does protein digestion start? C) What organ does lipid digestion start D) What organ does all food digestion end?

Label the diagram below using the terms found on page one of the lab. Some lines will not be used. You will need to draw in the gall bladder. You will also need to add some leader lines to some of the organs.
