people.chem.ucsb.edu27. a) Surface Tension: The tendency of molecules at the surface of a liquid to be pulled inward, resulting in a smooth surface. (The greater the intermolecular forces the greater the surface tension.) b) Viscosity: The resistance of a fluid (a gas or liquid) to flow: the higher the viscosity, the slower the flow.

Respiratory System Physiology - Duke University
histology.oit.duke.eduA lung with low compliance is stiff and hard to stretch and so is hard to fill with air. This is seen in the disease fibrosis (Fig. 5). Compliance of the lung is determined also by the surface tension generated at the air-water interfaces within the alveoli. The alveoli are air filled sacs lined with water. The attractive force
