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.

When intrapulmonary pressure drops below atmospheric pressure what is able to occur?
Inspiration occurs when the intrapulmonary pressure decreases to below atmospheric pressure
What is the result of intrapulmonary volume increase?
inspirtation
Why intrapleural pressure is always less than intrapulmonary pressure?
firstly the intraplural cavity is a closed space and pressure change is due to increased volume. For example with the contraction of the diaphram causing the intraplural cavity to increase in size and therefore reducing the pressure causing inspiration. Since the intraplural space is attached to the lungs, the lungs also expands, theoretically increasing space and therefore reducing volume. So if the intraplural pressure down, lung pressure will also go down and vise versa with exhilation. hope that helps.
What happens during the inhalation phase of breathing?
Inhalation is the process of taking air into the lungs. For this to occur, the air pressure inside the lungs must be lower than that of the external atmosphere as air flows from areas of higher pressure to lower pressure. This is achieved by the contraction of the external intercostal muscles and the relaxation of the internal intercostals which acts to pull the ribcage upwards and outwards, hence, increasing the volume of the thoracic cavity. The diaphragm also contracts to extend the cavity further downwards. Due to the function of the pleural membrane, the size of the lungs is increased which, in turn, creates an area of lower air pressure inside the lungs; hence, air is drawn into the lungs. Exhalation is the process of expelling air out of the lungs. For this to occur, the air pressure inside the lungs must be higher than that of the external atmosphere as air flows from areas of higher pressure to ones of lower pressure. This is achieved by the relaxation of the external intercostal muscles which bring the rib cage inwards and the diaphragm bulges upwards (recoiling to its original shape) respectively. The internal intercostal muscles contract so as to pull the rib cage further inwards, hence, decreasing the volume of the thoracic cavity and that of the lungs which, in turn, creates high pressure in the lungs; hence air is pushed out of lungs. In passive breathing, the movements of the diaphragm are responsible - the ribs aren't needed.
Movement of the diaphragm during inhalation?
During inhalation, the diaphragm contracts flattening out its usual dome shaped appearance. This has the effect of lengthening the lungs and increasing the intrapulmonary volume. When the volume increases, the pressure drops and air flows into the lungs.
Definition of intrapulmonary pressure?
Intrapulmonary pressure is the pressure within the air passage and the alveoli of the lungs.
When intrapulmonary pressure drops below atmospheric pressure what is able to occur?
Inspiration occurs when the intrapulmonary pressure decreases to below atmospheric pressure
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 happens to the intrapulmonary pressure when intrapulmonary volume increases?
Pressure increases as volume increases, granted the container stays the same.
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 pressure inside the lungs called?
Intrapulmonary pressure
When intrapulmonary pressure is above atmospheric pressure what is able to occur?
expiration
What is the difference between Intrapulmonary and Intrapleural?
Transpulmonary pressure
What pressure rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?

If your chest expands you would predict the intrapulmonary pressure to?
Decrease
Rises well over atmospheric pressure during a forceful cough?
