Answer to Question 1

ANS: B
Villi are small finger-like projections that extend from the small intestinal mucosa and increase its absorptive surface area. The ileum and jejunum are suspended in loose folds from the posterior abdominal wall by a peritoneal membrane called the mesentery. The lamina propria (a connective tissue layer of the mucous membrane) lies beneath the epithelial cells of the villi and contains lymphocytes and plasma cells, which produce immunoglobulins. The splenic vein drains the stomach and is not involved in absorption.

Answer to Question 2

ANS: C
The vermiform appendix is attached to the cecum. The vermiform appendix is not attached to the duodenum, the ileum, or the sigmoid.
