What structures make up the large intestine?

The large intestine is primarily made up of the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anal canal. This structure plays a crucial role in the digestive system as it is responsible for absorbing water and salts from the remaining indigestible food matter and compacts it into feces.

The cecum is the starting point of the large intestine, where it connects with the ileum of the small intestine. The ascending colon travels upwards from the cecum, followed by the transverse colon that runs across the abdomen. The descending colon goes downward, leading to the sigmoid colon, which connects to the rectum where feces are stored before being expelled through the anal canal.

While the other choices mention various components of the digestive system, they do not pertain to the large intestine. The duodenum, jejunum, and ileum are all parts of the small intestine. The stomach and small intestine consist of different sections of the gastrointestinal tract, and the liver and gallbladder are organs involved in digestion but are not part of the large intestine. Understanding these distinctions is key in identifying the correct components of the large intestine.
