Which of the following statements is incorrect?

Options

A. Faecal accumulation in the rectum initiates a neural reflex causing an urge for its removal
B. Reflex action for vomiting is controlled by medulla
C. Irregular bowel movements cause constipation
D. In diarrhoea absorption of food is increased

Answer

To determine which statement is incorrect regarding the process of digestion and absorption, we need to analyze the provided statements one by one.

1. **Understanding Fecal Accumulation**: The first statement mentions that fecal accumulation in the rectum initiates a neural reflex causing an urge for its removal. This statement is correct. When feces accumulate in the rectum, stretch receptors are activated, sending signals to the brain that create the urge to defecate.

2. **Evaluating Other Statements**: Since the question does not provide additional statements to evaluate, we can infer that the task is to identify any potential misconceptions or errors in the understanding of the rectum's role in the defecation reflex.

3. **Conclusion**: Based on the analysis, if there were other statements provided, we would compare them against established physiological facts. However, since the only statement discussed is correct, we can conclude that if there were any incorrect statements, they would likely contradict the established understanding of the rectum's role in initiating the urge to defecate.

4. **Final Answer**: Without additional statements to evaluate, we cannot definitively identify an incorrect statement. However, if other statements were provided, we would look for contradictions to the established physiological processes.
