Final answer:
A stool sample is used to obtain a specimen for bowel elimination, allowing healthcare providers to diagnose potential infections, conditions, and the presence of blood in the stool. The large intestine plays a key role in this process, and multiple diagnostic methods and treatments are available based on the findings.
Step-by-step explanation:
A specimen for bowel elimination can be obtained using a stool sample. During a microscopic examination of stool, typically performed over several days, healthcare providers can search for the presence of pathogens, such as bacteria and parasites, or check for the presence of blood, which could indicate certain types of infections or conditions.
The large intestine is an organ involved in excretion that helps to process waste materials. As undigested food material enters the colon, most of the water is reabsorbed; the intestinal flora within aid digestion, and the semi-solid waste is moved through the colon by peristaltic movements to the rectum. Finally, it is eliminated through the anus.
Other methods of diagnosing issues related to bowel elimination include breath tests, detection of antibodies in blood, and stool O&P exams. Depending on the condition suspected, treatments might vary and can include medications like metronidazole or specific antibiotics to target identified pathogens.
