LESSON OBJECTIVES
Describe the functions of the lungs.
Identify the parts of the lungs.
SUCCESS CRITERIA
The learners are able to give ways on how to keep their lungs healthy.
DISCUSSION
The teacher will let the kids breathe in and breathe out. Followed by asking these questions:
How did you feel during the breathing exercise?
How do you think the breathing exercise relates to the topic we're learning about – the lungs?
Right Bronchi
The bronchi (pronounced bron-kai) are like the main highways in our lungs. They are the big tubes that carry air in and out of our lungs.
Imagine your lungs as two big rooms, and the bronchi are the doors. When we breathe in, fresh air comes in through these doors. When we breathe out, the used air goes out the same doors.
Trachea
The trachea (pronounced tray-key-uh) is like the main pipe that carries air into our lungs. It's often called the windpipe. Picture the trachea as a long tube, just like a straw. When we breathe, the air follows this tube on its way to and from our lungs
Feel your throat gently – that's where the trachea is! It's like a sturdy pipe that stays open all the time, allowing air to move in and out.
At the bottom of the trachea, it splits into two smaller pipes called bronchi. These bronchi are like the main roads leading to different parts of our lungs.
Intercoastal muscles
The intercostal muscles (pronounced in-ter-kos-tal) are like the superhero helpers around our lungs. They are the muscles found between our ribs.
Every time you take a breath, your intercostal muscles help your ribs move. When you breathe in, they stretch, making room for your lungs to expand. When you breathe out, they relax.
The intercostal muscles work all day and night, whether you're playing, sleeping, or running around. They're always there, keeping the beat of your breath.
Not only do the intercostal muscles help with breathing, but they also play a role in protecting and supporting your lungs. They are like guardians ensuring your lungs stay safe and well-supported.
Heart
The heart is like a pump, a very special one! It pumps blood, and this blood is like a delivery truck carrying important stuff all over the city. The heart's job is to make sure the delivery trucks keep moving.
When we breathe in, it's like the balloons (lungs) are getting filled with fresh air. And when we breathe out, it's like they are letting go of the used air. It's a dance of breathing!
Here's where the heart and lungs become teammates. The heart sends the delivery trucks (blood) to the lungs to pick up oxygen, the good stuff that makes the delivery special.
Ribs
Your ribs are like a strong cage that wraps around your chest. Imagine them as the protective walls that keep your precious lungs safe.
Ribs are special bones because they're not too stiff or too bendy. They're just right, like a perfect mix of strong and flexible. This is important because they need to protect your lungs while allowing them to move when you breathe.
Your ribs and lungs work together like a dance team. When you breathe in, your ribs create room for your lungs to fill up with air. And when you breathe out, they come back together to give your lungs a gentle squeeze.
The top seven pairs are called "true ribs," and the next five are "false ribs." The last two pairs are extra special – they're called "floating ribs" because they're not directly attached to the front of your chest.
Diaphragm
The diaphragm (say dye-a-fram) is like a superhero muscle right below your lungs, and it plays a big role in helping you breathe.
Imagine the diaphragm as your breathing buddy. When you breathe, it's always there to help, moving up and down like a magic curtain.
Picture the diaphragm and lungs doing a dance together. When you breathe in, the diaphragm goes down, and your lungs fill with fresh air. When you breathe out, the diaphragm goes up, helping your lungs squeeze out the used air.
The diaphragm is not just for breathing; it's also a singing partner. When you sing, it moves up and down, helping you hit those high and low notes.
Air Sacs
The air sacs are at the very end of the bronchioles, which are like the roads leading to different parts of your lung playground.
When you take a deep breath, the air sacs open up like blossoming flowers. This is where the magic happens – your blood gets to meet the fresh oxygen from the air.
Think of the air sacs as squishy and flexible, just like your favorite playground balloons. They can expand when you breathe in and squeeze back when you breathe out.
DO IT:
Imagine you are a doctor. Explain how you would educate someone on the importance of maintaining healthy lungs.
CROSS CURRICULAR
HELE
Healthy Living: Impact of lifestyle choices on lung health, including the effects of smoking, air pollution, and nutrition.
Music:
Breathing Exercises in Music: Explore the connection between breath control and playing wind instruments. Engage students in breathing exercises that musicians use to enhance lung capacity.
REAL LIFE APPLICATION
The learners are able to give value and importance of their lungs and how they can keep their lungs healthy in their own ways.
EVALUATION
"LUNG JOURNAL ENTRY"
Imagine you are a lung cell, and you want to tell a friend about your important job in the body. Write a journal entry explaining who you are, what you do, and why your role is essential for keeping the body healthy.
