The primary organs of inhalation are the lungs, which are responsible for exchanging oxygen and carbon dioxide during respiration. Air enters the body through the nasal passages or mouth, travels down the trachea, and into the bronchi, which branch into smaller bronchioles within the lungs. Alveoli, tiny air sacs in the lungs, facilitate the gas exchange process. Additionally, the diaphragm and intercostal muscles assist in expanding and contracting the thoracic cavity to facilitate inhalation and exhalation.
