INTRODUCTION:-
LARGE INTESTINE:-
The large intestine is shorter than the small intestine .It is called large intestine as it is wider than the small intestine.It is aaranged around the mass of small intestine in the form of a question mark ? .It is about 1.5 metres long .It lacks villi and microvilli .It shows three region :-

Caecum :- The caecum is small blind sac coming of the colon at the latter’s junction with the ileum.
The caecum bears a short slender worm like projection called the Vermiform appendix.

Colon:- It is wider than small intestine.It gives succulent apperance due to a series of constrictions.
The colon shows four region:-
Ascending colon
Transverse colon
Descending colon
Longitudinal colon

The bend between the ascending and the transverse colon is called right colic fixure or hepatic flexure and that between transverse and descending colon is termed left colic flexure or splenic flexure.

Rectum:- It follow the colon.It is about 15 cm to 20 cm long.The rectum has longitudinal folds and large blood vessels.

Function:- The large intestine mainly aids in the absorption of water , formation, temporary storage and elimination of faeces and excretion.

The colon of bacteria produce vitamin B and K which are absorbed.

SMALL INTESTINE:-
The small intestine is distinguisible into three regions a C shaped duodenum a long coiled middle portion jejunum and highly coiled ileum . Dopening of stomach into duodenum is guarded by pyloric sphincter ,
Ileum opens into large intestine.

In duodenum glands are also present in submucosa .
The innermost layer lining the lumen of the elementary canal is the mucosa .

This layer forms irregular force in the stomach and small finger like folding called villi in the small intestine.

The cells lining the villi produces numerous microscopic projection called microvilli giving a brush border appearance.

These modification increase surface area enormously. Villi are supplied with a network of capillaries and a large lymph vessel called lacteals.

 

STOMACH:-
The stomach located in the upper left portion of the abdominal cavity has four major parts a cardiac portion into which the oesophagus opens

, fundic region which small dome like upper part that projects above the cardiac aperture , it oftens contain gas or air.

A pyloric portion which opened into the first part of a small intestine, it is a right narrow lower portion of the stomach, it comprises a wider pyloric antrum and narrow pyloric canal,

Body:- it is a main middle region of the stomach

In a surface of a stomach has numerous folds the gastric rugae . These folds by unfolding let the stomach expands to accommodate large meal about 2 l of food and water

Different foods remain in the stomach for different durations carbohydrate for only one or two hours, protein for up to 3 hours and fats for 3 to 6 hours .

Thus a fat rich food should be taken if the next meal is expected to be available after long time.

An athletes should take carbohydrate rich diet before competition.

When the stomach is empty its contraction stop and a period of rest begins. After a few hours contraction restart causing the feeling of hunger.

Ruminants have a large compound stomach.
These are mammals that chewed the cud.

The stomach of cattle buffaloes goats sheep mammals consists of four chambers – rumen , reticulum , omasum , abomasum.

The stomach of camels and dear lacks omasum.

Rumen is the largest chamber and receives oesophagus. In this chamber food undergoes mechanical and chemical breakdown.
