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 is the pressure inside the lung alveoli, while intrapleural pressure is the pressure in the pleural cavity. During normal breathing, intrapleural pressure is lower than intrapulmonary pressure, creating a pressure gradient that helps keep the lungs inflated.
What happens when pressure in the lung is greater than atmospheric pressure?
If the pressure in the lung is greater than atmospheric pressure, air will flow out of the lungs in order to equalize the pressure. This is called exhalation or breathing out.
What is also known as the intra-alveolar pressure?
Intra-alveolar pressure is also known as the machinal chain.
Why is it easier to breathe at sea level than at higher altitudes?
At sea level, the air pressure is higher, which means there is more oxygen available for breathing. At higher altitudes, the air pressure decreases, making it harder for the body to take in enough oxygen, leading to difficulty in breathing.
What happens during exhalation the diaphragm?
When breathing in, or inhaling, the diaphragm contracts, or tightens. When exhaling, or breathing out, the diaphragm expands, or loosens.
What does atmospheric pressure play a part in?
Breathing
What pressure rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapleural pressure rises and falls with breathing phases but eventually equalizes with atmospheric pressure. This pressure difference aids in lung expansion and ventilation by creating a pressure gradient for air to flow into and out of the lungs.
What pressures rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
Pleural cavity pressure?
The pleural cavity pressure is a negative pressure within the space between the lungs and the chest wall, which helps to maintain the expansion of the lungs during breathing. This negative pressure is created by the opposing forces of the lung's natural elastic recoil and the chest wall's tendency to pull outwards. A disruption in this pressure can lead to breathing difficulties.
What is the use of breathing holes in extinguisher?
To release excess pressure
Does pressure breathing assist blood back to the heart?
MAYBE
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure is the pressure inside the lung alveoli, while intrapleural pressure is the pressure in the pleural cavity. During normal breathing, intrapleural pressure is lower than intrapulmonary pressure, creating a pressure gradient that helps keep the lungs inflated.
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.
What is the best barometric pressure for optimal breathing?
The best barometric pressure for optimal breathing is typically around 760 mmHg, which is considered standard atmospheric pressure at sea level. This level of pressure allows for the lungs to efficiently exchange oxygen and carbon dioxide during respiration.
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".
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 partial pressure of oxygen can be calculated by multiplying the percentage of oxygen in the air by the total pressure. In this case, 20 percent of 6.3 ATM is 1.26 ATM. Therefore, the scuba diver is breathing oxygen at a partial pressure of 1.26 ATM.
