There are a number of places in the body where the pressures are lower than atmospheric, or negative. For example,
1- When we breathe in (inspire) the pressure in the lungs must be lower than atmospheric pressure. The lung pressure during inspiration is a few centimeters of water negative.
no
It is a negative pressure shell that fits the upper body. It is used to provide negative pressure to patients which provides a pressure gradient to move air into and out of 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.
surfactant- the substance that your lungs produces. Also continuous pressure from the air in there.
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.
