Transcript

  • 1. ORGANS OF DIGESTION Chapter 8 Presentation Nora Tabor
  • 2. SALIVARY GLANDS
    • Salivary glands in the oral cavity produce saliva. This watery and slick fluid allows food to be swallowed with less danger of choking. Saliva also contains the digestive enzyme called amylase.
    • There are three pairs of salivary glands:
    • Paratoid glands
    • Submandibular glands
    • Sublingual glands

  • 4. GALLBLADDER
    • The bile produced by the liver is stored in the gallbladder. Bile travels down the hepatic duct and up the cystic duct into the gallbladder. The GB responds to the fat in the chyme and sends it into the common bile duct where it is carried to the duodenum to be emulsified.
  • 5.  
  • 6. PANCREAS
    • The pancreas produces two important secretions for digestion; buffers and pancreatic enzymes. Buffers neutralize chyme and pancreatic enzymes chemically digest carbohydrates, fats and proteins. The pancreas also produces the hormones insulin and glucagon which regulate the levels of glucose in the blood.

  • 8. LIVER
    • The liver, a large organ located in the right upper quadrant of the abdomen, has several functions:
    • Processes the nutrients absorbed by the intestines
    • Detoxifies harmful substances in the body
    • Produces bile
    • Bile is important for digestion of fats and lipids because it breaks up large fat globules into much smaller droplets, making them easier to digest in the watery environment inside the intestines. This process is called emulsification.
