1) Surfactant keeps it from collapsing completely, but
2) Air pressure inflates it beyond the minimum
(the lower pressure around it is developed by the chest wall & the diaphragm.)
alveolar fluid
The type of air that keeps a beach ball inflated is kinetic energy.
This condition is known as emphysema. It is characterized by damage to the alveoli in the lungs, leading to a loss of elasticity in the alveolar walls. Over time, this can result in the alveoli becoming over-inflated and eventually rupturing, causing difficulty breathing and other respiratory issues.
Intrathoracic pressure
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
NO
The word "cat" is an example of a compound alveolar as it is composed of the alveolar consonants /k/ and /t/.
A balloon remains inflated because the pressure of the air or gas inside the balloon is greater than the pressure of the air outside the balloon. This creates a force that keeps the rubber surface of the balloon stretched tight, preventing it from collapsing.
Alveolar macrophages, aka DUST CELLS.
Alveolar ridge in Yoruba can be translated as "ilẹ̀ iigboori."
Pulmonary alveolar proteinosis (PAP) is a rare disease of the lungs.
The gas molecules inside the balloon collide with the walls of the balloon, creating pressure that pushes against the balloon's surface and keeps it inflated. This is due to the kinetic energy of the gas molecules in constant motion.
