No air exchange happening. This occurs at the end of inspiration or at the end of expiration.

When intrapulmonary pressure is above atmospheric pressure what is able to occur?
expiration
What pressure rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
What is pressure equal to?
Pressure = force divided by area p = F / A.
What do isobars connect?
lines on a map joining points of equal atmospheric pressure
What are rthe lines which adjoin different places with same pressure?
Isobar (meteorology), a line connecting points of equal atmospheric pressure..
When intrapulmonary pressure drops below atmospheric pressure what is able to occur?
Inspiration occurs when the intrapulmonary pressure decreases to below atmospheric pressure
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.
When intrapulmonary pressure is above atmospheric pressure what is able to occur?
expiration
What would occur when he atmosheric pressure is higher than intrapulmonary pressure?
When the atmospheric pressure is higher than intrapulmonary pressure pressure, inspiration will not take place.
What is Intrapulmonary pressure?
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.
What pressure rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
Rises well over atmospheric pressure during a forceful cough?
Intrapulmonary pressure
What pressures rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
What is the result of inspiration and expiration?
This occurs within the respiratory system. During inpiration, the intercostal muscles contract, the diaphragm descends, and the rib cage rises. The thoracic cavity volume increases, stretching the lungs, and the intrapulmonary volume increases. This causes the intrapulmonary pressure to drop. Air flows into the lungs until the intrapulmonary pressure equals the atmospheric pressure. During expiration the intercostal muscles relax, the diaphragm rises, and the rib cage descends. The thoracic cavity volume decreases, causing the the lungs to recoil, and the intrapulmonary volume decreases. This causes the intrapulmonary pressure to rise, and the air flows out of the lungs until the intrapulmonary pressure equals the atmospheric pressure.
Definition of intrapulmonary pressure?
Intrapulmonary pressure is the pressure within the air passage and the alveoli of the lungs.
What is the pressure difference between the external air and the pleural cavity when inhalation just begins?
In inspiration, intrapulmonary pressure drops 3mm/Hg below atmospheric pressure and air flows into the lungs.
How does the human body resist the atmospheric pressure?
because our body pressure is equal to the atmospheric pressure.
