There is greater pressure the deeper you go in water. So if you go too deep, the pressure in the human lungs will be so great and too much that the persons lungs will collapse.

What happens when pressure is lower inside the lungs than outside the lungs?
atmospheric
Why does the lung collapse if intrapleural pressure is not maintain?
Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.
What happens if pollution enters the human body?
it can be harmful to the lungs
What happens during inhalation phase of breathing?
Pressure within the thorax decreases and air is drawn into the lungs
What happens to the volume of your chest cavity when you enhale?
The volume of the chest increases due to the decrease in pressure in the lungs.
How does the pressure of the pleural space compare to the lungs?
Normally, the pressure in the lungs is greater than the pressure in the pleural space surrounding the lungs
In a human puncture of the thoraic wall but not of the lungs itself will cause?
As the pressure increases in the space between the chest wall and the lungs from an influx of blood, the collapse of the lung due to a relatively low pressure (within the lung) will occur.
What happens to pressure in the lungs when tyou inhale?
the lungs recoil/contract to push air out using its smooth muscle
When intraalveolar pressure exceeds atmospheric pressure what happens?
intrapleural pressure exceeds atmospheric pressure, but lungs don't collapse because intra-alveolar pressure increases, too (4 mmHg pressure gradient stays same)
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.
When does pressure in your lungs increase?
Pressure in the lungs increases during exhalation-when you breath out
How is intrapleural pressure maintained?
Intrapleural pressure is the pressure difference between the lungs and the pleural cavity of the lungs.
