What is terminal ileum?
The terminal ileum is the most distal segment of the small intestine and hosts many toxic substances, including bacteria, viruses, parasites, and digested food. Therefore, it is lined by a specialized lymphoid tissue of the immune system.
What is ileal resection?
Ileocecal resection is the surgical removal of the cecum along with the most distal portion of the small bowel—specifically, the terminal ileum (TI). This is the most common operation performed for Crohn disease, though other indications also exist (see below).

What is peristalsis 1m?
Explanation: Peristalsis results from involuntary contraction and relaxation of muscles present in the alimentary canal or some other tube-like structure in the body.

What is peristalsis quizlet?
What is peristalsis? the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wavelike movements that push the contents of the canal forward.

peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.
What are villi for Class 7?
Villi (singular villus) are finger-like outgrowths on the inner walls of the small intestine. The villi increase the surface area for absorption of the digested food.
Which part of the brain controls peristaltic movement?
The process of peristalsis is controlled by the medulla oblongata.
Which muscles play role in peristaltic movement?
Smooth muscles (non-striated muscles) help in bringing about involuntary movement in body such as peristalsis (movement of food in alimentary canal). These muscles are found in posterior part of oesophagus, stomach and intestine which undergo peristaltic movement in gastrointestinal tract.
