Airways are the passages in our body that allow air to travel to and from the lungs. They start from the nose and mouth, leading down through the throat, and branch into smaller tubes called bronchi. These tubes help deliver oxygen to the lungs, which is essential for our body to function properly. When we breathe, air enters through the nose or mouth, travels down the trachea, and into the bronchi. The airways also help filter out dust and germs, keeping our lungs healthy. Proper airway function is crucial for activities like exercise and even just resting, as it ensures we get enough oxygen.
