As the volume of space above the pulled down diaphragm increases, air rushes into the lungs and they inflate, bringing fresh oxygenated air into the respiratory system.
When the diaphragm contracts and moves downward, it increases the volume of the thoracic cavity, creating a negative pressure that draws air into the lungs. This process is essential for inhalation, as it allows the lungs to expand and fill with oxygen-rich air. Additionally, the downward movement of the diaphragm helps to push abdominal contents downward, contributing to the overall mechanics of breathing.
Inhalation
The diaphragm is the primary muscle responsible for breathing. When it contracts, it moves downward, creating a vacuum in the chest cavity which draws air into the lungs. When it relaxes, the diaphragm moves back up, pushing air out of the lungs.
The outward rise and inward fall of the belly during breathing is due to the movement of the diaphragm muscle. When you inhale, the diaphragm contracts and moves downward, pushing the abdominal organs outward. When you exhale, the diaphragm relaxes and moves upward, allowing the abdominal organs to move inward.
The diaphragm contracts during the inhalation phase of respiration. When it contracts, it moves downward, increasing the volume of the thoracic cavity and causing air to rush into the lungs.

the diaphragm. It is right above the heart and lungs, and expands and contracts when you breathe in and out. You can almost feel it move down a little, when you release air.
The diaphragm is the primary muscle responsible for breathing. When it contracts, it moves downward, creating a vacuum in the chest cavity which draws air into the lungs. When it relaxes, the diaphragm moves back up, pushing air out of the lungs.
The outward rise and inward fall of the belly during breathing is due to the movement of the diaphragm muscle. When you inhale, the diaphragm contracts and moves downward, pushing the abdominal organs outward. When you exhale, the diaphragm relaxes and moves upward, allowing the abdominal organs to move inward.
When your diaphragm contracts and moves downward, it increases the volume of the chest cavity, causing a decrease in air pressure in the lungs. This negative pressure then allows air to be drawn into the lungs through the airways.
The diaphragm contracts during the inhalation phase of respiration. When it contracts, it moves downward, increasing the volume of the thoracic cavity and causing air to rush into the lungs.
The base of the lungs sits above the diaphragm, which is the primary muscle involved in respiration. The diaphragm separates the thoracic cavity, where the lungs are located, from the abdominal cavity. During inhalation, the diaphragm contracts and moves downward, creating negative pressure that allows air to flow into the lungs.
the diaphragm contracts and moves downward, and the rib cage moves upward and outward.
When you inhale, the diaphragm contracts and moves downward. This movement creates more space in the chest cavity, allowing the lungs to expand and fill with air.
