Question

Sacculus Rotundus is present in
A. Duodenum of rabbit
B. Ileum of frog
C. Ileum of rabbit
D. Colon of rabbit

Answer 1

Hint: This part includes lymphoid tissue and the enlargement of the large intestine. The colon of a rabbit has upward, transverse and downward parts. The ascending colon, which occupies mainly the ventral abdomen, is very long.

Complete Answer:
- Rabbits are small mammals of the family Leporidae of the order Lagomorpha. Oryctolagus Cuniculus comprises the European rabbit genus and its relatives, the world's 305 domestic rabbit breeds. Sylvilagus contains 13 wild rabbit species, including seven varieties of cottontail.
- The rabbit has a simple and large stomach. The intestine of the rabbit functions similar to that of other animals, but anatomical differences exist. The caudal flexure of the duodenum is long, coiled and can be known as the transverse section of the duodenum. At the terminal end of ileum the sacculus rotundus occurs. It includes lymphoid tissue and the enlargement of the large intestine.
- The colon of a rabbit has upward, transverse and downward parts. The ascending colon, which occupies mainly the ventral abdomen, is very long. Taenia and haustra are in the first segment, while the second portion is organized in the dorsal segment of the abdomen. The transverse and descending colons are anatomically identical to other species.

Thus, the correct answer is option C. i.e., Ileum of rabbit.

Note: The rabbit is a herbivorous animal, so that its food channel is long enough to be fed vegetables. The food channel has a long, variable-diameter, coiled tube. It is suspended in the mesentery in the body cavity. It is composed of the mouth, tongue, teeth, cavity of the bucco-pharyngeal, esophagus, small intestines, stomach, large gut and anus.
