Typically, the volume of gas is much larger than that of the liquid or solid, with thin films separating gas pockets. Another definition of foam is a bubbly liquid, particularly if the bubbles, or froth, are undesirable.

WebFoam cells are a rich source of proinflammatory mediators and there is strong evidence that support a central role for inflammation in all phases of the atherosclerotic process which … Foam cells are formed when circulating monocyte -derived cells are recruited to the atherosclerotic lesion site or fat deposits in the blood vessel walls. Recruitment is facilitated by the molecules P-selectin and E-selectin, intercellular adhesion molecule 1 ( ICAM-1) and vascular cell adhesion molecule 1 ( VCAM-1 ).

Liquid foams can be used in fire retardant foam, such as those that are used in extinguishing fires, especially oil fires. In some ways, leavened bread is a foam, as the yeast causes the bread to rise by producing tiny bubbles of gas in the dough. The dough has traditionally been understood as a closed-cell foam, in which the pores do not connect with each other. Cutting the dough releases the gas in the bub…
