Final answer:
Paralytic ileus affects the muscular layer of the alimentary canal, leading to symptoms like abdominal pain, bloating, and inability to pass stool due to impaired smooth muscle contractions necessary for digestion and movement of food.
Step-by-step explanation:
Sadaf is suffering from a condition called paralytic ileus, which affects the muscular layer of the alimentary canal. This layer is essential for the propulsion of food through the digestive tract by means of coordinated contractions known as peristalsis in the small intestine and large intestine. Due to the paralysis of the smooth muscle in these areas, Sadaf may experience symptoms such as abdominal pain, bloating, nausea, vomiting, and inability to pass stool or gas, which are indicative of a stalled digestive process. Additional complications may include malnutrition and dehydration if the condition persists without medical intervention.
Segmentation helps in mixing the food with digestive juices while slow peristalsis in the small intestine allows for increased nutrient absorption. However, since the muscular layer's contractions are halted in the paralytic ileus, these critical digestive functions are impaired, leading to the symptomatic effects Sadaf is experiencing. Immediate medical attention is required to address the underlying causes and provide supportive care to minimize complications from this condition.
