WebMay 23, 2024 · A foam is a substance made by trapping air or gas bubbles inside a solid or liquid. 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 white blood cells that consume invaders to try to get rid of them. In this case, they consume cholesterol and thus appear foamy. Continued foam cell activity causes further damage to your endothelium. Plaque growth. Dead foam cells and other debris continue building up. So, the fatty streak turns into a larger piece of plaque.
