What is the path of inhaling?

Inhaling begins when air enters the body through the nose or mouth. It travels down the trachea, branching into the bronchi that lead into each lung. Within the lungs, air moves into smaller bronchioles and finally reaches the alveoli, where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. This process is facilitated by the diaphragm and intercostal muscles, which expand the chest cavity.
