less than the atmospheric pressure
Negative pleural pressure typically ranges from -3 to -8 cm H2O during normal breathing, with larger negative pressures generated during forced inspiration. The negative pressure in the pleural space helps maintain lung inflation by creating a pressure gradient for air to flow into the lungs during inspiration.
you are under to much pressure
yes it does
Not much. You create slight changes in pressure when you breathe, but it's almost insignificant.
Yes, as much as possible.
The diaphragm moves down when you breathe in, so your lungs will expand to take in as much oxygen as possible.
Yes; it is possible but not likely.
The negative effects of peer pressure can include early use of substances and sexual experimentation before one is emotionally ready. Negative peer pressure can also effect self-esteem in harmful ways for the person trying to fit in.
It is normal for fuel tanks to develop positive and negative pressure as the car operates and the temperature changes.
It's possible, but much more likely there is a leak somewhere.
They wanted to keep as much control as possible.
You need to create a difference in air pressure between the inside and outside of the straw for air to come out. By sucking on the straw, you create low pressure inside, causing the atmosphere's higher pressure to push the air through the straw and into your mouth.
