When we inhale, our diaphragm contracts, creating a vacuum that draws air into the lungs. This air fills the alveoli, tiny air sacs where gas exchange occurs; oxygen from the air enters the bloodstream while carbon dioxide is expelled. Inhaling facilitates the delivery of oxygen to our body's tissues, supporting cellular functions and overall health. However, inhaling harmful substances can damage lung tissue and impair respiratory function.
