Difference between Small and Large Intestine

The small intestine is the longest and has the smallest diameter of all the segments, measuring between 4.5 and 7 meters, while the large intestine refers to its larger diameter the length is roughly 1.5 meters long.

Here are some of the main differences between them to help you understand how both differ:

Small Intestine Vs Large Intestine:

Small Intestine:

The small intestine, which runs between 4.5 to 7 meters in length, has the smallest diameter of any of the organ’s sections.

This structure resembles a tube and is situated in the belly between the stomach and the big intestines.

There are spherical folds on the small intestines’ interior surface. These folds are circular folds and villi. This villus is a little finger-like protrusion.

These villi help to increase the surface area of the plant, allowing more nutrients to be absorbed.

Due to the existence of circular folds, which delay the transit of food through the intestines, the food remains in this area for a longer period of time for the purposes of digestion and absorption.

The small intestines is made up of three sections: the duodenum, the jejunum, and the ileum.

The duodenum, which begins at the end of the stomach, is the smallest of the three. It has a little hole that passes through the pancreatic and biliary systems.

Large Intestine:

This intestine refers to its larger diameter.

The length is roughly 1.5 meters long. It is also referred to as the colon or the large bowel. The alimentary canal ends at the large intestines.

It is also known as the colon or big bowel. The alimentary canal is terminated with the large intestines.

The big intestines is therefore exposed to the outer world via the anus.

With the smooth muscles that make up the large intestines, the meal is expelled through the anus, these muscles tighten and release.

What is Difference between Small Intestine and Large Intestine?

The small intestine is a large part of food digestion and nutrient absorption occurs, whereas in the large intestine water absorption and the synthesis of vitamins take place.

Let’s discuss the difference between them as follows:

Small Intestine Large Intestine
A segment of the intestine that links the stomach to the large intestine is known as the small intestine.The large intestine, the gut’s terminal part is longer and broader than the small intestines.
It has a length ranging from 4.5 to 7.0 meters.These intestines are shorter in length (1.5 m).
It is diminutive (3.5-4.5 cm).It is wider (4.0 -6.0 cm).
This intestines consist of the duodenum, jejunum, and ileum.The cecum, colon, rectum, and anal canal are the four sections of the large intestines.
The small intestine’s interior material is coated up with circular folds.The inside surface of the large intestines lacks circular folds.
Villi are found on the inside surface of the small intestines.They lack villi.
Peyers patches can be found in some areas of the small intestines.It lacks Peyer’s patches.
Circular layers of longitudinal muscles are seen in the small intestines.The large intestines’ longitudinal muscles are organized into three bands known as Teniae coli.
The tiny intestines have no haustra.The haustra live in the big intestines.
Epipolic appendages are absent in the small intestines.Epipoplic appendages can be found in the large intestines.
The wall of the small intestines is slippery.The large intestine’s wall has sacs in it.
It is where digestion takes place.They do not perform the task of digestion.
Hormones are released from the small intestines.Hormones are not released by the large intestines.
They exhibit minute motions.It has a rather constant configuration.
The majority of the nutrients in the digested meal are absorbed in the small intestines.The indigestible fraction of the food is absorbed by the large intestines, which also absorb water.


After reading this article you learned a lot about the differences between the small intestine and the large intestine.

The alimentary tract is made up of two portions of the animal’s gut: the small and large intestines. The small intestines are responsible for both food digestion and absorption of nutrients.

The purpose of each structure in the animal body is the primary distinction between the small and large intestines.
