Final answer:
A "twisting" of the bowel causing obstruction is called a volvulus, which can lead to a serious medical emergency. In the context of the alimentary canal, propulsion refers to the movement of food, and the cecum is the part of the large intestine attached to the appendix. Intestinal wall inflammation is known as diverticulitis.
Step-by-step explanation:
A "twisting" of the bowel causing obstruction is called a volvulus. This condition occurs when a loop of intestine twists around itself and the mesentery that supports it, leading to a bowel obstruction. It's a serious condition that can cut off the blood supply to the affected part of the intestine and requires immediate medical attention.
If we're talking about the processes occurring in the alimentary canal, propulsion is the correct answer which refers to the movement of food through the digestive tract.
Regarding the part of the large intestine that attaches to the appendix, the answer is the cecum.
When the wall of the intestine becomes inflamed, this condition is known as diverticulitis, similar to how inflammation of the appendix is called appendicitis.
