Large intestine
Definition
It is the intestinal part which extends from the stomach to the large intestine
It is the terminal intestinal part which extends from the appendix to the anus

Muscle bands
Consist of circular layer of longitudinal muscle
Consist of longitudinal muscles in three bands known as Tineae coli
Wall surface
Smooth
Sacculated
Absorption
Involved in absorption of nutrients from the digested food
Involved in absorption of water and electrolytes from the undigested portion of food
Function
Helps in digestion of the undigested or partially digested food by secreting intestinal fluids
It expels out the waste material through the anus
Definition of Small Intestine
The small intestine extends from a lower part of the stomach to a large intestine part. It is a very long and narrow tube with a smooth wall surface. It appears as a coiled tube in the abdominal region and comprises three components from the proximal end to the distal end. Duodenum, jejunum and ileum are the three sections of the small intestine. It performs several functions in the abdominal region like digestion of food, absorption of nutrients etc. Definition of Large Intestine
The large intestine extends from the appendix to the anus. It appears as a wider and short tube with a sacculated wall surface.
