Where are the lungs located in relation to the diaphragm?

The lungs are anatomically situated above the diaphragm. The diaphragm is a dome-shaped muscle that separates the thoracic cavity, where the lungs are located, from the abdominal cavity below it. When the diaphragm contracts during breathing, it moves downwards, allowing the lungs to expand and fill with air. This positioning is critical for proper respiratory function, as the diaphragm plays a vital role in creating the pressure changes necessary for inhalation and exhalation. Understanding this relationship between the diaphragm and the lungs is essential for fitness instructors, as it informs their knowledge about respiratory mechanics and the importance of proper breathing techniques during exercise.
