Descends. When you inspire, the diaphragm descends, the thoracic volume inreases, the intra-thoracic pressure drops. The difference in the environmental pressure and the intra-thoracic pressure causes air to flow into the lungs.

What takes place you initate and exhale?

When you inhale, your diaphragm contracts and moves downward, expanding the chest cavity and drawing air into the lungs. The oxygen in the air is then exchanged with carbon dioxide in the blood. When you exhale, the diaphragm relaxes and moves upward, compressing the chest cavity and pushing air out of the lungs.


Does the diaphragm deal with inspiration or expiration?

The diaphragm primarily deals with inspiration. When the diaphragm contracts and moves downward, it creates more space in the chest cavity, allowing air to flow into the lungs. During expiration, the diaphragm relaxes and moves upward passively as the air is forced out of the lungs.


How does diaphragm help during the inhaling and exhaling process?

During inhalation, the diaphragm contracts and moves downward, allowing the lungs to expand and fill with air. This creates a vacuum in the chest cavity, drawing air into the lungs. During exhalation, the diaphragm relaxes and moves upward, forcing air out of the lungs.


What is the role of the diaphragm in the anatomy of breathing?

The diaphragm is a dome-shaped muscle located below the lungs that plays a crucial role in breathing. When you inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and fill with air. This action allows you to take in oxygen. When you exhale, the diaphragm relaxes and moves back up, pushing air out of the lungs. In summary, the diaphragm helps regulate the process of breathing by controlling the volume of air in the lungs.


Does the diaphragm move up on inhalation?

No, the diaphragm moves down during inhalation. This action increases the space in the chest cavity, allowing the lungs to expand and fill with air. The downward movement of the diaphragm creates negative pressure in the chest, which draws air into the lungs.
