The Digestive System discussion
Science
ASSESSMENT
Did you know it takes at least six hours for food to get to the end of your small intestine, and then it takes an average of 40 hours for food to make it through your large intestine? That means the food you eat today is still with you tomorrow, and the day after that.
In this assessment, you will journal the hourly life of a fatty acid or a sugar molecule as it makes its final voyage through the digestive tract. You only need to journal the first seven hours of the digestive passage. This means you should have a total of seven journal entries.
Your journal entries should be creative and include descriptions of all the alimentary and accessory organs, including their secretions. You should also mention which type of digestion is happening in each organ and include the nervous or endocrine system controls that affect the digestion of your molecule. Remember, a fatty acid and a sugar molecule are digested and absorbed in a slightly different way. Be sure your journal covers the correct voyage for the molecule you choose.
