When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
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.
In a divergent nozzle, pressure will decrease as the flow area increases. This is due to the conservation of mass principle, where an increase in area causes a decrease in velocity and thus a decrease in pressure according to Bernoulli's equation.
The air pressure in your chest cavity increases when you are exhaling. For air to leave your lungs, it must be at a higher pressure than the air outside. Your diaphragm pushes up against your chest cavity causing the space in your lungs to get smaller. If the volume decreases, the pressure has to rise. Don't believe me? start exhaling, then close your mouth. Your cheeks will puff out because the pressure inside is greater than the pressure outside.
When you inhale, your diaphragm contracts and moves downward, while your rib cage expands. This creates a decrease in air pressure in your lungs, causing air to rush in through your nose and mouth. Oxygen is then absorbed into the bloodstream through the alveoli in the lungs.
When you inhale, the diaphragm and intercostal muscles contract, expanding the chest cavity. This expansion increases the volume of the lungs, causing a decrease in air pressure within them. Air moves from an area of higher pressure (outside the body) to an area of lower pressure (inside the lungs), resulting in inhalation.
The act of inhaling is to create low pressure in the lungs, causing the air in the atmosphere to rush in as it is moving from a higher pressure (outside in the atmosphere) to the lower pressure (created in the lungs). However the fact that air does move into the lungs means that there is no net change in pressure.

decrease in pH
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.

A decrease in temperature or a decrease in the number of gas molecules in the container will cause a decrease in gas pressure. Alternatively, if some of the gas molecules escape from the container, the pressure will also decrease.
A decrease in temperature or a decrease in the number of gas particles in the container will cause a decrease in gas pressure. Additionally, if some of the gas particles escape from the container, it will also lead to a decrease in pressure.
