When you take a deep breath and want to exhale it, but keep you nose and mouth close you will raise your intrathoracic pressure and secondary your abdominal and intracranial pressure.
So, because of secondary raise of brain pressure in the act of defecation for example some people (especially elderly people and those with constipation) will make an brain stroke.

Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure will equalize to atmospheric pressure during a breathing cycle, but intrapleural pressure should always be less than atmospheric pressure.
What is the speed of breathing air?
The speed of breathing air is not fixed. It depends on the size of the hole being breathed through and the pressure difference between the lungs and the atmosphere.
Is breathing internal of external force?
breathing in through your nose is internal, breathing out through your mouth is external.
Why the pressure increases when a diver goes deep the sea?
Because pressure increases the further down you go. A unpressurized tank would collapse under this weight. Actually, the pressure in the tank is not to prevent it from crushing, but to allow it the diver to breathe. The greater the pressure in the tank, the greater the amount of breathing air you have available. As ambient pressure increases (ie by descending), your lungs require more air to fill them, as you are then breathing compressed air into your lungs. If you tried to breathe atmospheric pressure at depth, you could not fill your lungs. The deeper you go, the harder it is to breathe... Try breathing through a 6ft snorkel to the surface, and see how difficult it is to inhale. Therefore, the tank is pressurised, 1/ to allow you to breathe effortlessly at depth, 2/ to give you more time at depth, and 3/ to keep water out of the tank.
When was Circular Breathing created?
Circular Breathing was created on 2006-05-01.
What pressure rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
What does atmospheric pressure play a part in?
Breathing
What pressures rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
Is breathing considered osmosis?
No. Breathing is not osmosis. It is more of diffusion. When you breathe in the air, the diaphragm flattens and there is a low-pressure created in the lungs. Air from high pressure surrounding enters lungs to balance this pressure difference, which is Diffusion only.
Does pressure breathing assist blood back to the heart?
MAYBE
What is the use of breathing holes in extinguisher?
To release excess pressure
What partial pressure of oxygen is a scuba diver breathing if the total pressure is 6.3 ATM and 20 percent of the air is oxygen?
The answer to the question what partial pressure of oxygen is a scuba diver breathing if the total pressure is 6.3 atm and 20 % of the air is oxygen is 1.26 atm (atmospheres).
How does the thorax enable us to breathe?
the volume of breathing in increases and when breathing out it decreases, the pressure in Inhaling decreases and the Exhaling increases.
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure will equalize to atmospheric pressure during a breathing cycle, but intrapleural pressure should always be less than atmospheric pressure.
Does the attitude of an area affects the breathing rate?
Yes the altitude of the area does affect the breathing rate becaue the higher you go the lower the air pressure and the the lower you go the lower the air pressure.
How is breathing effected in space?
Breathing is not possible in space. Except inside a space suit or other container filled with gas at significant pressure. But then you're not actually breathing "in space".
Does negative pressure breathing involve pushing or forcing air into the lungs?
no
