    The Bottled Balloon

    The movement of the diaphragm causes changes in the volume of the chest cavity, which drives air flow into and out of the lungs. When the diaphragm contracts and flattens, it increases the volume of the chest cavity. This decrease in pressure causes air to flow into the lungs through the trachea and bronchi. When the diaphragm relaxes and returns to its original dome shape, it decreases the volume of the chest cavity. This increase in pressure causes air to flow out of the lungs.

    The Breathing System

    THE BOTTLED BALLOON ACTIVITY


    Let’s Recall
    Identify the Parts of the breathing system based on their function.
    1. The exchange of gases occur in this part.
    2. A hollow tube that serves as passageway of air into the lungs.
    3. It serves as channel for airflow in which the air is warmed, cleaned, and
    moistened.
    4. Hairlike tubes that connect to the alveoli that serves as passageway of air.
    5. Two branching tubes that connect the trachea to the lungs.
    6. The air enters and being filtered by the tiny hairs called cilia.
    Trace my path!!!
    • The air we breathe goes through the , nose
    Nasal, cavity
    and then through the ortrachea
    windpipe,
    which separates into two branches, called
    bronchimany times inside the
    . The bronchi subdivide
    lungs and finally becoming hair-like tubes called
    . In the last part of the terminal
    bronchioles are tiny bubble-like bunch of structures
    bronchioles
    called or airsacs.
    alveoli
    Bottled Balloon
    Objectives:
    1. Explain how the lungs work.
    2. Describe how the movement of the diaphragm helps the air go in
    and out of the lungs .

    Materials:
    1 two-liter empty plastic bottle
    3 balloons (1 big, 2 small),
    2 sturdy straw
    1 pair of scissors
    5 rubber Bands.
    • A constructed model of the human chest cavity
    Procedure:
    1. Using a pair of scissors, cut the bottom out of the 2-liter
    plastic bottle.
    2. Create two holes that are apart from each other in the cap of
    the plastic bottle. Make sure that each hole is just big enough
    for a straw to fit through.
    3. Stick the two straws through the two holes of the bottle cap.
    4. Place one balloon on the end of each straw, and secure them
    with rubber bands.
    5. Stick the balloon ends of the straws through the bottle
    opening and screw the lid on tightly.
    6. Stretch out the larger balloon and place it over the open
    bottom of the bottle. Secure it with the rubber band as tightly as
    possible.
    Procedure:
    7. Pull the larger balloon down; that is, away from the bottle, in order
    to blow up the two small balloons.
    8. Push the larger balloon towards the bottle in order to let the air out
    of the two small balloons.
    9. Write down your observations.
    Guide Questions:

    Q4. What does each part of the constructed


    lung model represent?
    (bottle, straw, small balloons, big balloon)
    Q5. What happens as you pull down the balloon at
    the bottom of the model?
    Q6. What happens as you push up the balloon?
    Q7. How does the movement of the diaphragm
    cause the air to go in and out of the lungs?
    Q8. What might happen if you prick the balloon
    Answer
    • Q4. What does each part of the constructed
    lung model represent?
    • (bottle, straw, small balloons, big balloon)

    •. plastic bottle = chest cavity


    • Two straws = bronchi
    • Two balloons = lungs
    • Larger balloon = diaphragm
    Guide Questions:

    Q5. What happens as you pull down the


    balloon at the bottom of the model?

    The two balloons expand


    Guide Questions:

    Q6. What happens as you push up the balloon?

    The two balloons loosen up and return to their


    original size
    Guide Questions:

    Q7. How does the movement of the diaphragm


    cause the air to go in and out of the lungs?
    The movement of the diaphragm affects the air
    pressure inside the chest cavity by either
    decreasing or increasing the space, thus allowing
    air to go in and out of the lungs.
    Guide Questions:

    Q8. What might happen if you prick the


    balloon?

    If one of the balloons is pricked, it will not


    inflate anymore because the air will
    escape.
    Have you experienced being in a jam-packed
    train?

    How can you relate this to the process that


    makes air move in and out of the lungs.
    How does the movement of the diaphragm
    cause the air to go in and out of the lungs?
