increases
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.
When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity. This leads to a decrease in intraalveolar pressure, causing air to flow in from the atmosphere to equalize the pressure, resulting in inhalation.
The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it. When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.
density decreases as air pressure increases
When you exhale, the pressure inside the thorax increases slightly due to the contraction of the diaphragm causing a decrease in thoracic volume. This increase in pressure helps to push air out of the lungs.
It decreases, allowing air to flow.

It decreases, allowing air to flow in.
During quiet breathing, the intrapleural pressure decreases during inspiration as the diaphragm contracts and the thoracic cavity expands, leading to a decrease in pressure inside the lungs. During expiration, intrapleural pressure increases as the diaphragm relaxes and the thoracic cavity decreases in volume, causing an increase in pressure inside the lungs.
When the diaphragm is pulled down, the volume of the thoracic cavity increases, and the air pressure in the thoracic cavity decreases. This causes inhalation.
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 moves downward, increasing the volume of the thoracic cavity. This leads to a decrease in intraalveolar pressure, causing air to flow in from the atmosphere to equalize the pressure, resulting in inhalation.
When you take a breath, the diaphragm contracts and when it does, it drops down. This increases the size of the thoracic cavity. Air pressure is now lower in it than outside. Air moves from a high pressure to a low pressure. Air rushes in and the reverse happens when the diaphragm relaxes.
As temperature increases, water pressure also increases. Conversely, as temperature decreases, water pressure decreases. This relationship is due to the fact that water expands when heated and contracts when cooled, affecting the pressure it exerts within a closed system.
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
When breathing in, or inhaling, the diaphragm contracts, or tightens. When exhaling, or breathing out, the diaphragm expands, or loosens.
OK, do you mean when the airway is open? If open, a slight decrease in pressure momentarily. If closed, a larger decrease in pressure.
