Which of the following is not a part of the large intestine?

The jejunum is not a part of the large intestine; it is actually a section of the small intestine. The small intestine consists of three main parts: the duodenum, jejunum, and ileum. Each of these sections plays a crucial role in the digestion and absorption of nutrients.

In contrast, the large intestine includes sections such as the ascending colon, transverse colon, and descending colon. These parts are involved in the absorption of water and electrolytes, as well as the formation and storage of feces. Understanding the anatomy of the digestive system is important, as it highlights the distinct roles and functions of both the small and large intestines.
