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 .
