Figure 5: Absorption is a complex process, in which nutrients from digested food are harvested. absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitudei.e., the maximum displacement or movement of a point on the waveand, as the wave passes through a substance, its amplitude steadily decreases. With the help of bile salts and lecithin, the dietary fats are emulsified to form micelles, which can carry the fat particles to the surface of the enterocytes. The mechanical and digestive processes have one goal: to convert food into molecules small enough to be absorbed by the epithelial cells of the intestinal villi. Q.2.
