Verified step by step guidance

Understand the process of inhalation: Inhalation occurs when air is drawn into the lungs, requiring the coordination of multiple body systems.

Identify the role of the respiratory system: The respiratory system is responsible for gas exchange, including the intake of oxygen during inhalation and the release of carbon dioxide during exhalation.

Identify the role of the muscular system: The muscular system, specifically the diaphragm and intercostal muscles, plays a key role in creating the pressure changes necessary for inhalation.

Explain the interaction: During inhalation, the diaphragm contracts and moves downward, while the intercostal muscles contract to expand the rib cage. This increases the thoracic cavity's volume, reducing pressure and allowing air to flow into the lungs.

Connect the systems: The respiratory system relies on the muscular system to facilitate the physical mechanics of breathing, demonstrating their interaction during inhalation.
