The difference in structure of the large intestine from that of small intestine. Introduction: The digestive tract starts from the mouth and extends to the anus. The muscular tube of digestive tract consists of esophagus, stomach, and intestine (small and large intestine). The small intestine is a tubular organ that extends from stomach’s pyloric sphincter to the large intestine. Large intestine starts from the right side and descends into the pelvis.

Summary Introduction

To explain:

The difference in structure of the large intestine from that of small intestine.

Introduction:

The digestive tract starts from the mouth and extends to the anus. The muscular tube of digestive tract consists of esophagus, stomach, and intestine (small and large intestine). The small intestine is a tubular organ that extends from stomach’s pyloric sphincter to the large intestine. Large intestine starts from the right side and descends into the pelvis.
