Decrease
When you breathe in, your chest expands as the diaphragm muscles contract and move downward. This creates more space in the chest cavity, allowing the lungs to expand and fill with air. The expansion of the chest is essential for the process of inhalation.
When you breathe in, your diaphragm moves down and your rib cage expands to allow more air into your lungs, causing your chest size to increase. This expansion of the chest cavity allows the lungs to fill with air, providing oxygen to the body and facilitating the exchange of gases in the respiratory system.
When breathing in, or inhaling, the diaphragm contracts, or tightens. When exhaling, or breathing out, the diaphragm expands, or loosens.
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.
Boyle's law states that the pressure of a gas is inversely proportional to its volume at a constant temperature. In the context of respiration, Boyle's law explains how changes in lung volume affect air pressure within the lungs, leading to the movement of air in and out during breathing. When the diaphragm contracts and the chest cavity expands, lung volume increases, causing a decrease in pressure and allowing air to flow into the lungs.
The intrapulmonary pressure is the pressure in the alveoli. Intrapulmonary pressure rises and falls with the phases of breathing, but it ALWAYS eventually equalizes with the atmospheric pressure.
It expands
During inspiration, the chest cavity expands as the diaphragm contracts and moves downward, while the ribcage lifts and expands outward. This increase in space lowers the air pressure within the lungs, causing air to flow in to equalize the pressure. This process allows for oxygen to enter the lungs and carbon dioxide to be expelled.
During inhalation, the diaphragm contracts and moves downward, increasing the volume inside the chest cavity. This increase in volume causes a decrease in pressure, leading to air rushing into the lungs to equalize the pressure. As a result, the chest expands to accommodate the incoming air.

the chest cavity expands.
I am not in the medical field. But if a lung collapses it means that there is air getting between the lung and the chest cavity creating pressure against the lung. A tube placed in the chest wall will relieve the pressure there. When the lung fills with air it pushes the air out of the tube. Then you can block the tube to give the chest cavity back the slight vacuum it had before. That is why your chest expands when you breate in. I hope this is right and I am not stepping on any toes out there.
The movement of the rib cage changes the air pressure in the chest cavity depending on the physical activity the person is performing. If they are running, the air pressure will be constantly increasing and decreasing, leading to stress on the rib cage.
When you breathe in, your diaphragm moves down and your rib cage expands to allow more air into your lungs, causing your chest size to increase. This expansion of the chest cavity allows the lungs to fill with air, providing oxygen to the body and facilitating the exchange of gases in the respiratory system.
when you inhale..(take in oxygen)..the air fills up the lungs, the ribcage expands and the muscle sheet called the diaphragm pushes downward and flattens as you inhale ..whn you ehale the muscle returns back to domed-shape
When you breathe in, your diaphragm muscle contracts and moves downward, causing the chest cavity to expand. This expansion lowers the air pressure in the lungs, allowing air to flow in through the nose or mouth.
Chest pain and pressure very winded - what does this mean?
