Lesson Background

Regurgitation and vomiting are two different processes in which the animal may appear to be “throwing up,” but these are two distinct processes. Regurgitation is quiet and involves undigested food matter as the food has not passed into the stomach yet. Vomiting is a more vigorous process so it can be heard, abdominal muscles can be seen in use, and the vomitus looks digested.

To diagnose what is going on, veterinarians may take radiographic images, in order to see what the organs of the animal looks like.

Activities

Students, in a drag and drop manner, will separate attributes by whether they pertain to vomiting or regurgitating. 

Common misconceptions and challenge points

The differences between regurgitation and vomiting may be difficult to understand. To combat this, emphasize the things that students can see and hear in these two process, and have them contrast them.

Students may also be confused about how to look at radiographs. Remind them that these are just to illustrate what a radiograph may look like, as it shows the insides of the animal, and that they do not need to be able to read them.

Assessment

Students will answer three short multiple choice questions to check what they have learned throughout this lesson.
