8. Process of Digestion
The process in which the complex and insoluble
contents of food are converted into simpler and
soluble substances, suitable for absorption and
assimilation is called Digestion . Food is digested by
the enzymes.

10. •The mouth is the entrance for the digestive system.
• Here the food is chewed to break it up into small pieces.
•The floor of the mouth contains a tongue.
•The jaws are lined by teeth in our mouth.
• These are called incisors, canines, premolars and molars.
•The teeth chew the food well.

11. The tongue has several papillae or sensory
buds. It is the organ for the sense of taste.
Large taste buds
Small taste buds

12. There are three pairs of salivary glands . They are,
1. PAROTID: It is found at the back of the throat.
2. SUBMAXILLARY: It is found below the lower jaw bone.
3. SUBLINGUAL: It is found at the base of the tongue.
• Salivary glands secrete saliva.
• It contains an enzyme called ptyalin.
• This converts Starch into maltose.
• Lysozyme present in saliva acts as an antibacterial agent.

14. • Pharynx is a common passage for food and air.
• It opens into the Oesophagus.
• It extends up to stomach.

15. • Stomach is an extremely elastic bag .
• It can store very large quantities of food .
• Oesophagus communicate with the anterior portion of the
stomach through cardiac opening which is guarded by
cardiac sphincter muscles .
• The opening from the stomach into the deodenum is
known as pylorus. It is guarded by pyloric sphincter
muscles . It prevents the passage of food into the duodenum .
• The food stays in the stomach for some times for the
action of the enzymes . Continued….

16. • When the food is partly digested, the pyloric sphincter
muscle relaxes periodically, releasing small quantities of
partially digested food into the duodenum.
• Gastric glands are found on the wall of the stomach.
• They secrete gastric juice. This juice consists of enzymes ,
pepsin, renin and gastric lipase.
• Pepsin converts protein into peptones.
• Renin converts milk protein caseinogens into casein.
• Gastric lipase begins the digestion of fat.

• Pancreatic lipase can not react directly on fat.
• The bile salts reduce the surface tension of water and can
change the fat into creamy liquid with tiny particles.
• The pancreas lipase reacts with tiny lipid particles
