When inhaling, air enters the body through the nose or mouth, then travels down the trachea (windpipe) into the bronchi, which branch into the lungs. Within the lungs, air moves through smaller passages called bronchioles and finally reaches the alveoli, tiny air sacs where gas exchange occurs. Oxygen from the air passes into the bloodstream, while carbon dioxide is expelled from the blood to be exhaled. This entire process is essential for respiration and providing oxygen to the body's tissues.
