Basics on the topic My Body - Breathing and Oxygen Cycles


Breathing in Elementary School

Put your hand on your chest or on your stomach and observe what happens for a while. Do you feel your hand rising and then falling with your chest or stomach? In this way, you can consciously perceive your breathing, because inhaling and exhaling are exactly responsible for this. But how does breathing work in simple terms? This is exactly what this text is about, and you will get to know the way of breathing for primary school.

First of all, it is important to clarify the following question: What is breathing?. Breathing is the process by which we absorb oxygen from the air and transport it to all body cells, where it is used to generate energy . Because breathing is so important to us, the next section will explain breathing to children.

How does breathing work?

Have you ever noticed that breathing just works without you having to think about it? Breathing is a reflex and happens automatically, just like your heart beats. It is particularly important that breathing works like this: This way, you can sleep deeply and soundly and still continue to breathe. But you can also consciously control your breathing and hold your breath, for example, when diving. But how do inhaling and exhaling work? * In order for you to inhale, your chest is expanded. This allows room for air to enter your body through your nose and mouth. * Your body warms, cleans, and humidifies the air right after you inhale it. This is how your sensitive lungs are protected. * As you breathe in, the air moves down your throat. The pharynx is the tube that connects the nose and mouth to the trachea. This is a tube for air. * The trachea merges into the bronchi, which transport the air further into two lungs. You can imagine the bronchial tubes like the branches and roots of a tree: they also keep dividing until they are only as thin as a hair. * At the end of the bronchi are many tiny air sacs. They almost look like they're hanging from the ends like grapes. Something very important also happens here: oxygen from the air gets into our blood via the walls of the alveoli. * This is where the oxygen combines with the red blood cells. They then ensure that the oxygen is distributed throughout the body. * When we consume oxygen, carbon dioxide is produced. This is released into the air when we breathe out. The journey now goes backwards: The air with the used oxygen gets back into the alveoli, then flows from the bronchi into the trachea and through the throat. * In exactly the same way that the air entered your body, the air then leaves your body when you exhale - namely through the mouth or nose. Have you ever noticed that you have to inhale and exhale more often and more deeply when you exert yourself? Because when you exercise, your body uses more oxygen and therefore exhales more carbon dioxide. Be careful next time, maybe after running a race with your friends.

Because breathing is a very important and interesting topic in elementary school, you will also find a video on breathing, especially for children, on sofatutor. This will definitely help if you get worksheets on breathing in elementary school. If you would like to learn more about your body, you can also watch the video for Blood Circulation in primary school.

Frequently asked questions about My Body - Breathing and Oxygen Circulation

How do the lungs work explained simply for children? People have lungs to breathe. It is an organ in the chest that supplies our body with oxygen. In addition, it also helps to remove carbon dioxide. This is the stuff that's produced when we use oxygen. What happens when we breathe out? By breathing out, the carbon dioxide that is produced when we use oxygen is carried out of the body .

Transcript My Body - Breathing and Oxygen Cycles

Take a deep breath a few more times and the balloon is ready. But how does the air you breathe actually get into the balloon? Let's find out together by learning about "My Body - Breathing and the Oxygen Cycle." Breathing works without you having to think about it. We call this a reflex. The blinking of your eyes or your heartbeat are also reflexes. The reflex of breathing is especially handy while you're asleep. But unlike your heartbeat, you can intentionally control your breathing and hold your breath. This is useful when diving or if someone passes gas. Now, let's take a look at exactly how breathing works in the body! When you inhale, your chest expands. This makes room for air to enter your body through your nose and mouth.... into your body. When you exhale, the air flows back out of your body the same way. Immediately after inhaling, the air in your nasal cavity is warmed, cleansed, and humidified. This protects your sensitive lungs. The air then flows through your pharynx. The pharynx connects the area of the nose and the area of the mouth ... with the trachea. The trachea is a tube for air. It feels hard and wavy on the outside. Press pause and feel your trachea for a moment. The trachea opens into the bronchial tubes. The bronchial tubes carry the air further into the lungs. Like the roots of a tree, the bronchial tubes continue to divide. At the end, they are as thin as a hair. At the end of the bronchi are many air sacs. Like grapes, they hang from the ends of the bronchial tubes. There is something ESPECIALLY important happening there, and we're going to take a close look at it now: The oxygen in the air can get into the blood in our veins via the walls of the air sacs. There, the oxygen combines with the red blood cells, which ensures... that the oxygen is distributed throughout the body. Before we exhale, carbon dioxide, or used oxygen, is released into the air in the air sacs. And then it starts: we exhale. The air with the carbon dioxide flows through the bronchial tubes, ... and the trachea ... through the pharynx and comes out of our body again through the mouth or nose. And then everything starts all over again! Breathing is similar to the heartbeat: The more you exert yourself, ... the more frequently and deeply you have to breathe in and out. This is because your body uses more oxygen during exercise, so you breathe in more, ... and exhale more carbon dioxide. Let's briefly summarize: Breathing is a reflex. However, you can control breathing somewhat. Air enters the body through the nose and mouth ... through the pharynx ... and the trachea ... and through the bronchial tubes into the lungs and ... up to the air sacs in the lungs. The air sacs are tiny, but you have an incredible number of them. That's where oxygen is exchanged for carbon dioxide. So where's the balloon? OH, the balloon is out of control.
