Nutrition in Human Beings (Digestive System in Human Body):

Basic organs of the human digestive system are:
1.Mouth(Buccal cavity),
2.Oesophagus(Food pipe),
3.Diaphragm(Sheet),
4.Stomach(J shaped),
5.Small intestine,
6.Large intestine,
7.Rectum,
8.Anus.

- Alimentary canal/Gut is the entire path of food from the mouth to anus.
- The small intestine is longer than large intestine but still, it is called as it is thinner.
-Peristaltic movement: When the slightly digested food enters the food pipe, the walls of the food pipe starts contraction and expansion movements to move the food along the gut. This movement of walls of food pipe is called peristaltic movement.
-Sphincters: These are circular muscular structures which control the movement of the substance through them. Normally, they remain closed. When movement is required, they open. There are many sphincters in the gut.

Glands of the human digestive system are:
1.Salivary glands,
2.Liver,
3.Pancreas.

- Salivary glands in our mouth produce saliva which contains an enzyme called salivary amylase which digests the starch present in the food into sugar.
- The pancreas lies behind the lower portion of the stomach. It secretes pancreatic juice which contains many digestive enzymes.
- The liver secretes greenish yellow liquid called bile. Bile is temporarily stored in the gallbladder before it is sent to the small intestine through the bile duct.
