    • Process of Digestion The process in which the complex and insolublecontents of food are converted into simpler andsoluble substances, suitable for absorption andassimilation is called Digestion . Food is digested bythe enzymes. To view the animation please go to the next slide
    • Mouth Salivary glands Oesophagus Liver Gall bladder stomach Duodenum Pancreas Large intestine Small intestine AnusClick here to go to Animation list
    • •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. Pharynx Tongue TeethClick here to go to evaluation Click here to go to Animation list
    • The tongue has several papillae or sensorybuds. It is the organ for the sense of taste. Large taste buds Small taste buds
    • 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.Click here to go to evaluation
    • Parotid sublingual Parotid Submaxillary Submaxillary sublingualClick here to go to Animation list
    • • Pharynx is a common passage for food and air. • It opens into the Oesophagus. • It extends up to stomach.Click here to go to evaluation
    • • 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….Click here to go to evaluation
    • • When the food is partly digested, the pyloric sphinctermuscle relaxes periodically, releasing small quantities ofpartially 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.To view the animation of the functions please go to the next side.
    • Gastric pepsin Renin Casein lipaseClick here to go to Animation list
    • Liver a Gall bladder Bile salts Pancreatic lipase Pancreas Duodenum • 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 particlesClick here to go to Animation list
    • pancreatic duct.
    • Enzyme Conversion Trypsin Converts protein and peptons into polypeptides. Corboxy peptidase Converts polypeptides into amino acids . Chymotrypsin Digests milk protein. Pancreatic amylase Converts starch into maltose Pancreatic lipase Converts emulsifide fat into fatty acids and glyserolTo view the animation of the functions please go to the next slide
