1. Digestive System By: Jimmy Elliott Anatomy 5/23/07 Mrs. Hoyle

2. Digestive System Diagram

3. Digestive System Your digestive system is a place where foods broken down, nutrients are taken from the food and the waste is produced. Your digestive system is made up of multiple organs and all have different functions.

4. Functions of Digestive System Mechanical digestion happens in the mouth and along the esophagus Chewing Peristalsis Chemical digestion occurs in the mouth with help from salivary enzymes In the stomach by gastric juices such as HCl acid. Most occurs in the small intestines Pancreatic juice (neutralize acid) Gall bladder (bile emulsify fat) Enzymes (digest food)

5. The Tongue The Tongue helps to move food to mix it with saliva to form a bolus so you are able to swallow it. The taste buds are what makes you to be able to taste the food.

6. The Uvula The Uvula helps to stop food from going into your nasal passage way. The Uvula is also a cause for why people snore. Epiglotis covers the airway and prevents food from going down the wrong pipe!

7. The Salivary Glands There are three pairs of salivary glands called the Parotid glands, Submandibular Glands, and the Sublingual Glands. Saliva is made in all of these glands and saliva helps to break down the carbohydrates in your mouth.

8. The Esophagus This is were the food and liquids you drink and eat go from the pharynx and into your stomach. The Esophagus’s muscles contract and force the food downward into your stomach.

9. The Small Intestine This is were most of the food products are absorbed were the good and healthy parts are used and the waste is moved on into your large Intestine. Most of your chemical digestion takes place here. Absorption and transport of nutrients from the lumen to the blood

10. The Pancreas The Pancreas is were your insulin is created and the blood sugar is regulated and maintained. The Endocrine and exocrine glands are located in the Pancreas

11. The Liver The Liver detoxifies blood that is sent there from the Intestines. The Glucose (sugar) that is in your blood is maintained here. Gall Bladder – produces bile and help in digestion of fat.

12. The Large Intestine The Large Intestine absorbs all of the left over water and nutrients that were left behind and brings all of the unused items to the anus for termination.

13. Do you remember your biochem? Carbohydrates Foods such as bread, starches, fruits and veges. monosccharides: fructose, galactose, and glucose Disaccharides: Lactose, maltose and sucrose Polysaccharides: starch, cellulose Proteins Foods such as chicken, beef, fish, nuts and legumes Proteins are broken down into its building block unit of amino acids Lipids Foods such as butter and oils Building blocks are glycerol and 3 fatty acids.
