The word "lung" refers to a part of our body that helps us breathe. It is located in our chest, and we have two of them. They are like big sponges that fill up with air when we inhale and then release the air when we exhale. We need our lungs to live and they are connected to our mouth and nose through air tubes called bronchi. The word "lung" is usually used when talking about breathing or respiratory health. For example, if someone has a cough or trouble breathing, they might need to see a doctor to check their lungs.
