  move.

21
Name the organs through which a piece of food
would pass if you ate it.

• Mouth to esophagus to stomach to small intestine
  to large intestine to rectum to anus to toilet

22
How is food prevented from going down the
windpipe?

• Epiglottis
• the epiglottis folds down to a more horizontal
  position, with its superior side functioning as
  part of the pharynx. In this manner it prevents
  food from going into the trachea and instead
  directs it to the esophagus, which is posterior.

23
What causes food to move down the esophagus?

• Peristalsis Muscles

24
What are the two functions of the hydrochloric
acid in your stomach?

• Chemical Digestion breaking down food and
  breaking down protein molecules
• Kills harmful bacteria in the stomach

25
What are the two types of digestion? Describe the
difference between the two.

• Mechanical Digestion physical change
• Chemical Digestion chemical change
• Mechanical breaks the food into smaller pieces
  with changing its chemical make up.
• Chemical breaks the food down into a new
  substance.

26
What are internal stimuli? Give an example.

• An internal stimulus is something from within
  that gets you do 'do' something. An example of
  this would be "you feel a hunger pain, so you go
  get some food".

27
What are external stimuli? Give an example.

• An external stimulus is something from outside
  (the environment) that gets you to 'do'
  something. And example of this would be "you see
  a commercial about food, so you go get some
  food".

28
Give 2 examples of animals that changed through
the process of natural selection and how these
have helped them to survive.

• Birds on the Galapagos Islands
• Different beaks depending on food available
• Tortoise on the Galapagos Islands
• Neck and leg length depending on food available
