Final answer:
The 13th step of a SOAP SUDS ENEMA likely involves observing and reporting on the effects of passing food items through tubing representing the intestines, as part of a lab activity to understand digestion.
Step-by-step explanation:
The 13th step of a SOAP SUDS ENEMA in a classroom lab setting involves a simulated activity to understand the digestive process. From the provided information, it seems the experiment has a series of steps where students use a section of tubing to simulate the intestine, with simulated chyme representing the partially digested food, and additional food items to study the movement through the intestinal tract. By this stage in the experiment, students would likely be observing and reporting the results of the earlier steps such as the insertion and passing of food items through the tube and the activity's effect on the simulated chyme, as well as cleaning and storing of lab materials.
The 13th step of a SOAP SUDS enema is to drain the liquid from the rectum. After the enema has been administered and the liquid has been held in the rectum for a specified amount of time, the next step is to release the contents of the rectum. This removes any waste materials or impurities that were loosened and softened by the enema solution.
