Answer

Thoracic cavity volume increases Explanation 1. Identify the sequence of events Contraction of inspiratory muscles leads to an increase in thoracic cavity volume. 2. Determine the immediate effect Increased thoracic cavity volume results in increased intrapulmonary volume. 3. Analyze pressure changes As intrapulmonary volume increases, intrapulmonary pressure decreases. 4. Resulting action Decreased intrapulmonary pressure causes air to flow into the lungs.
