What occurs to the diaphragm during inhalation?
Understand the Problem
The question is asking about the physiological changes that occur to the diaphragm when a person inhales, specifically which action the diaphragm performs during this process.
Answer
The diaphragm contracts and moves downward during inhalation.
The diaphragm contracts and moves downward during inhalation, increasing the size of the thoracic cavity and decreasing pressure to allow air to enter the lungs.
Answer for screen readers
The diaphragm contracts and moves downward during inhalation, increasing the size of the thoracic cavity and decreasing pressure to allow air to enter the lungs.
More Information
The movement of the diaphragm is crucial for the mechanical aspect of breathing. When it contracts and moves downward, it increases the volume of the thoracic cavity, reducing the pressure inside, which allows air to flow into the lungs. This process is essential for efficient breathing.
Tips
A common mistake is thinking that the diaphragm moves upward during inhalation because it seems counterintuitive. Remember that downward movement increases the chest cavity's space.
