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 is the relationship between intrapulmonary pressure and atmospheric pressure?

they are equal


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

True


What pressures rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?

Intrapulmonary Pressure


What are the steps involved in inhalation and exhalation?

During inhalation the diaphragm contracts/flattens and pulls the lungs downward increasing their intrapulmonary volume. As intrapulmonary volume increases intrapulmonary pressure drops. As atmospheric pressure is greater than intrapulmonary pressure, air flows down its pressure gradient into the lungs. During exhalation the process is reversed. Diaphragmatic relaxation compresses the lungs decreasing their volume and increasing their pressure. As intrapulmonary pressure is greater than atmospheric pressure, air once again flows down its pressure gradient out of the lungs.


What if intrapulmonary pressure is equal to atmospheric pressure?

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


Why does air flow out when you exhale your lungs?

The intrapulmonary pressure is greater than the atmospheric pressure and air is going to flow from high pressure to low pressure.


Difference between 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 relationship of speed of sound to the atmospheric pressure?

There is a relationsship of speed of sound to the temperature but not to the atmospheric pressure.


What causes air to flow out of your lung during expiration?

As the diaphragm and intercostal muscles relax the volume of the lungs decreases. As intrapulmonary volume goes down, intrapulmonary pressure goes up. When the pressure inside the lungs exceeds the atmospheric pressure outside the lungs, air flows out and we exhale.


What is the pressure inside the lungs called?

Intrapulmonary pressure


What happens to the intrapulmonary pressure when intrapulmonary volume increases?

Pressure increases as volume increases, granted the container stays the same.


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.

Does Mars have extreme pressure?

The atmospheric pressure of Mars is 6 millibars as opposed to the 1,013 millibars of atmospheric pressure on Earth. Thus, its atmospheric pressure in relationship to Earth is extremely low.
