108 LABOKATOBY MANUAL 



Directions: On the models and charts locate the 

 parts of the alimentary canal. 



A. Alimentary Canal. At the back of the mouth 

 note the funnel-shaped cavity, the pharynx or throat. 

 What other openings are there into this cavity? What 

 openings lead from this cavity? 



Note the gullet or esophagus, a small tube leading 

 from the pharynx to the stomach. 



What is the position of the stomach in the body? 

 Its approximate size and shape? 



Following the stomach is a long, very much coiled 

 tube, the small intestine. This tube connects with a 

 larger tube known as the large intestine. 



B. Glands. The salivary glands of the mouth, the 

 parotid, the sub-maxillary, and the sub-lingual were 

 studied in Exercise 71. 



In the internal walls of the stomach are small glands 

 known &s gastric glands. These discharge their secre- 

 tion into the stomach. 



Intestinal glands are located in the walls of the first 

 part of the small intestine. Other glands which pour 

 their secretions into the small intestine are the pancreas 

 and the liver. 



The pancreas is a long, lobulated gland lying 

 beneath the stomach. The liver, the largest gland in 

 the body, lies just beneath the diaphragm above and 

 to the right of the stomach. 



From the chart make a drawing of the alimentary 

 canal and glands, labeling parts.
