What does the large intestine consist of?

The large intestine is primarily made up of the ascending colon, transverse colon, descending colon, and sigmoid colon, leading to the rectum. Each of these segments plays a significant role in absorbing water and electrolytes, and in the formation and storage of feces. The structure of the large intestine allows for the efficient handling of waste material after the digestion of food has occurred in the small intestine.

Focusing on the other options, the rectum and anus are parts of the digestive tract that relate to the elimination process but do not encompass the entirety of the large intestine. The duodenum and jejunum are parts of the small intestine, which is where most of the nutrient absorption occurs, not the large intestine. Additionally, the stomach is involved in the initial digestion of food and is not part of the large intestine itself. Thus, the correct answer accurately reflects the key components and structure of the large intestine.
