The folding of the mucosa in the intrapulmonary bronchus increases the surface area for gas exchange by providing more space for the diffusion of gases between the air in the lungs and the blood vessels. This increased surface area allows for more efficient oxygen uptake and carbon dioxide release in the respiratory system.

What happens to the intrapulmonary pressure when intrapulmonary volume increases?
When intrapulmonary volume increases, the intrapulmonary pressure decreases. This creates a pressure gradient that allows air to flow from higher pressure outside the lungs to the lower pressure inside the lungs during inspiration.
What does intrapulmonary pressure do during quiet inspiration?
Intrapulmonary pressure decreases during quiet inspiration as the diaphragm and external intercostal muscles contract, expanding the thoracic cavity. This leads to an increase in lung volume and a decrease in intrapulmonary pressure, causing air to flow into the lungs.
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.
What is the medical term meaning narrowing of the bronchus?
Bronchostenosis is abnormal narrowing of the bronchus.
Why is the right primary bronchus a site for obstruction?
The right primary bronchus is slightly wider and at a steeper angle than the left primary bronchus. This is due mostly to the fact that the heart occupies a larger portion of the left lung than the right. This makes the right lung bigger so it needs a wider bronchus for air to fill it up. Plus since the heart is a bit more to the left, the left bronchus branches off at more of an angle. The combination of these two factors makes the right bronchus more susceptible to obstructions if a foreign object travels down the trachea leading the bronchus.
Definition of intrapulmonary pressure?
Intrapulmonary pressure is the pressure within the air passage and the alveoli of the lungs.
What is the Delorme procedure?
used to treat rectal prolapse.The Delorme procedure involves the resection of only the mucosa (inner lining) of the prolapsed rectum. The exposed muscular layer is then folded and stitched up and the cut edges of mucosa stitched together.
What is the singular to Bronchus?
The noun bronchus is the singular form of bronchi.
What is the plural of bronchus?
Bronchi is the plural of bronchus.
What happens to the intrapulmonary pressure when intrapulmonary volume increases?
When intrapulmonary volume increases, the intrapulmonary pressure decreases. This creates a pressure gradient that allows air to flow from higher pressure outside the lungs to the lower pressure inside the lungs during inspiration.
Does bronchus come after bronchiole?
No, bronchioles branch of a bronchus.
What is the main difference between a bronchus and a bronchiole?
A bronchiole has no cartilage in its wall, a bronchus does.
How would you use bronchus in a sentence?
bronchus diverges from the windpipe. bronchus enters lung and provides air passage.
Comparing with the right main bronchus the left main bronchus?
The right main bronchus is wider, shorter, and more vertical than the left. The left main bronchus is smaller in caliber,but 5 cm longer than the left bronchus.
What does intrapulmonary pressure do during quiet inspiration?
Intrapulmonary pressure decreases during quiet inspiration as the diaphragm and external intercostal muscles contract, expanding the thoracic cavity. This leads to an increase in lung volume and a decrease in intrapulmonary pressure, causing air to flow into the lungs.
What principal bronchus is more vertical?
right principal bronchus
Reflection of bronchus?
Reflection of bronchus is caused by a reflection of the pleura.
