The breathing system is like a pump that brings fresh air in and pushes used air out of our body.
Our breathing system is like a amazing two-way highway that manages the flow of air in our body. π« Just like how a car needs fuel to run, our body needs oxygen to function, and the breathing system makes sure we get this vital gas while removing waste gases. It's working 24/7, even when we're sleeping, to keep us alive and healthy.
When we breathe in, air enters through our nose or mouth (like the entrance of a tunnel). The air then travels down a long tube called the windpipe - it's like a flexible straw that filters and warms the air before it goes deeper into our body.
The air reaches our lungs, which are like two spongy balloons. Inside these balloons are millions of tiny air sacs, similar to tiny bubble wrap bubbles. Here, oxygen from the air moves into our blood, while carbon dioxide from our blood moves into the air sacs.
The whole process is powered by a special muscle called the diaphragm. It's like a pump that moves up and down. When it moves down, it creates space for our lungs to fill with air (breathing in), and when it moves up, it pushes air out (breathing out).
Our brain automatically controls our breathing rate, like a smart thermostat adjusting room temperature. It makes us breathe faster when we exercise and slower when we rest, ensuring we always have the right amount of oxygen.
