Answer:
What is surface tension?
Explanation:
Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer.
Surface tension forces between mucosal surfaces play an important role in the pathogenesis of the disease. The obstruction of upper airway elicit the activation of autonomic nervous system, hypoxemia, and arousal from sleep.
