Respiratory system

The respiratory system is a vital network in our body that enables us to breathe. It comprises the nose, throat, windpipe, and lungs. When we inhale, air enters through the nose or mouth, travels down the trachea, and fills the lungs. Here, oxygen from the air passes into the bloodstream and carbon dioxide, a waste gas, is expelled during exhalation. This exchange of gases is crucial for providing oxygen to our cells and removing waste, supporting our survival and energy needs. Proper functioning of the respiratory system is essential for overall health.
