  • How do food molecules travel through the body. (List the steps from beginning to end)
    The stomach breaks down starches into glucose and proteins into amino acids
    Food enters the body through the mouth and goes to the stomach
    Amino acids and glucose enter the blood stream
    The blood brings the molecules to the cell where its used to produce energy
  • What is the circulatory system responsible for?
    taking in oxygen and releasing carbon dioxide
    pumping blood around the body and bringing molecules to cells
    storing glucose
    breaking down proteins and starch into amino acids and glucose
  • You believe that the human body works best if it gets molecules from food and air. Are you correct?
    No, the body works when lungs get air and the stomach gets food
    No, the body needs molecules from different foods
    Yes, the body works best with molecules from food and air
    No, the cells make all the molecules we need
  • Your friend has asthma. Why can't he exercise?
    he isn't getting enough sleep
    his cells don't have all molecules, but he can exercise
    he would need more molecules from air
    he isn't getting different types of food molecules
  • Your respiratory system stops working. Can you exercise?
    No, the molecules from air are too large for the cell
    Yes, the digestive system will work twice as hard
    No, the respiratory system wouldn't break down oxygen
    No, your cells can't work without oxygen
  • What is the respiratory system responsible for?
    storing glucose
    taking in oxygen and releasing carbon dioxide
    breaking down proteins and starch into amino acids and glucose
    pumping blood around the body and bringing molecules to cells
  • How does air go through the body. (label first step to last step)
    The cell takes in the oxygen and uses it to produce energy
    The alveoli transport the oxygen to the blood
    The nose and mouth take in oxygen and send it to the lungs
    The blood brings oxygen to the cell
  • You are tasked with making sure a diver is safe and healthy during a two-hour dive. What should you observe?
    how much food is digested while he is diving
    how many different types of foods the diver gets
    how much sleep the diver gets
    how much food and air molecules the diver gets
  • Which system contains the heart and all blood vessels?
    cells
    digestive
    circulatory
    respiratory
  • Which system contains the mouth, wind pipe (trachea) and lungs?
    respiratory
    cells
    digestive
    circulatory
  • What is the digestive system responsible for?
    breaking down proteins and starch into amino acids and glucose
    storing glucose
    pumping blood around the body and bringing molecules to cells
    taking in oxygen and releasing carbon dioxide
  • Would it be hard to exercise if your digestive system wasn't working? Why or why not?
    no, you'd just breathe in more air
    Yes, your cells would remain empty
    yes, because food wouldn't be broken down
    Yes, you wouldn't be able to sleep
  • Your digestive system results are in: starch is high, oxygen is none and glucose is low. Can you exercise?
    Yes, the body is functioning
    No, the digestive system isn't breaking down food
    No, the digestive system is putting together oxygen and glucose
    Yes, you need to breathe in more air
  • Which system contains the mouth, esophagus, stomach, small intestine and large intestine?
    circulatory
    respiratory
    digestive
    cells
