INTRODUCTION:-
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.
