Verified step by step guidance

Step 1: Begin by understanding the primary function of the large intestine. The large intestine is responsible for absorbing water and electrolytes from indigestible food matter, forming and storing feces, and housing gut bacteria.

Step 2: Break down the anatomy of the large intestine into its main parts: the cecum, colon, appendix, and rectum. Each part has distinct roles in digestion and absorption.

Step 3: Focus on the colon, which is the longest part of the large intestine. The colon is divided into four sections: ascending colon, transverse colon, descending colon, and sigmoid colon. Its primary function is to absorb water and salts from the remaining food matter.

Step 4: Compare the colon's function to the other parts of the large intestine. The cecum primarily receives chyme from the small intestine, the appendix is a vestigial structure with no significant role in water absorption, and the rectum stores feces before elimination.

Step 5: Conclude that the colon is the part of the large intestine primarily responsible for absorbing water, as its structure and function are specialized for this task.
