Respiratory system explained to kids

The respiratory system is a group of organs that work together to help you breathe. The main parts of the respiratory system are the lungs, which are a pair of spongy, air-filled organs that are located in your chest. The lungs take in oxygen from the air and then transfer it to your blood. The blood then carries the oxygen to the rest of your body. The respiratory system also helps to remove carbon dioxide and other wastes from your body. The carbon dioxide is a gas that is produced when your body breaks down food to use for energy. The respiratory system helps to get rid of this gas by allowing it to be exhaled (breathed out). The respiratory system is made up of several different parts, including the nose, throat, trachea (windpipe), and lungs. The nose is the entrance to the respiratory system. The air that you breathe in through your nose goes down your throat and into your trachea. The trachea is a tube that extends from your throat to your lungs. At the bottom of your trachea, there are two small tubes called the bronchi. The bronchi are the main tubes that carry air into your lungs. Once the air enters your lungs, it goes into tiny air sacs called alveoli. The alveoli are where oxygen from the air enters your blood. Your respiratory system is important because it helps to supply your body with the oxygen it needs to function. Oxygen is necessary for your cells to produce energy. Without oxygen, your cells would not be able to function and you would die.
