the lungs push against your chest when you breathe causing an almost flexing motion
The diaphragm contracts and moves downward during inhalation, which increases the volume of the chest cavity. This decrease in pressure in the chest cavity creates a pressure difference that allows air to flow into the lungs.
It increases.
The Diaphragm.
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.
When the diaphragm contracts, it becomes flatter in shape. This flattening of the diaphragm increases the volume of the chest cavity, allowing the lungs to expand and draw in air for breathing.
When you inhale, the volume of your chest cavity increases. This expansion is caused by the contraction of the diaphragm and intercostal muscles, allowing more space for the lungs to expand and fill with air.
inhaling
During inhalation, the size of the chest cavity increases as the diaphragm contracts and moves downward, while the intercostal muscles lift the ribcage upward and outward. This expansion lowers the pressure inside the chest cavity, allowing air to flow into the lungs. As a result, the volume of the thoracic cavity increases, facilitating the intake of air.
it contracts, pulling downwards to increase the volume in the chest.
When you inhale, the diaphragm, a dome-shaped muscle located at the base of the chest cavity, contracts and moves downward. This contraction increases the volume of the thoracic cavity, causing a decrease in pressure and allowing air to flow into the lungs. Additionally, the intercostal muscles between the ribs also contract, further expanding the chest cavity.
The volume of the chest cavity is reduced on exhalation. Imagine your lungs are balloons. Imagine the volume of a balloon full of air, compared to when it is not inflated. The balloon has a greater volume when it is inflated than when it is deflated - just like the lungs do!
When you inhale, the volume of your chest cavity increases. This expansion lowers the pressure inside your chest relative to the outside air, allowing air to rush in and fill your lungs. This process is driven by the contraction of the diaphragm and the expansion of the ribcage.
