Answer 1

5. Ans: Mechanical obstruction is the physical blockage of the intestine by a tumor, scar tissue, or another type of blockage that prevents intestinal contents from getting past the point of obstruction. One type of mechanical obstruction is caused by the bowel twisting on itself (volvulus) or telescoping into itself (intussusception). Mechanical obstruction can also result from hernias, fecal impaction, abnormal tissue growth, the presence of foreign bodies in the intestines, or inflammatory bowel disease (Crohn's disease).

Whereas Non-mechanical obstruction occurs when the normal wavelike muscular contractions of the intestinal walls (peristalsis), which ordinarily move the waste products of digestion through the digestive tract, are disrupted (as in spastic ileus , dysmotility syndrome, or psuedo-obstruction) or stopped altogether as in paralysis of the bowel walls (paralytic ileus)
