Absorption is whereby the digested food substances are entering our bloodstream. Assimilation is whereby the body makes use of these absorbed food substances that has entered our blood
absorption
Its function is to increase intestine surface area for more efficient absorption of digested nutrients. In different earthworm families, the typhlosole appears to have multiple origins.

Some absorption also happens there however, most of the absorption of nutrients happens in the small intestines with the help of the many enzymes to break down the food that is digested by the stomach.
Food is digested in the stomach, and this digestion continues to some degree in the small intestine. But it is largely in the small intestine that the nutrients are absorbed from the stream of digested materials. Anything not absorbed continues on to the large intestine for water extraction and further on to excrement.
absorption of nutrients by increasing the surface area available for absorption. This increased surface area allows for more efficient absorption of nutrients from the digested food passing through the small intestine.
Absorption
Assimilation is the use of digested and absorbed materials to make new body parts.
The lumen is the cavity where digested food passes through and from where nutrients are absorbed, in the small intestine.
Villi in the intestines increase the surface area for absorption of nutrients from digested food. They contain blood vessels and lacteals that help transport the absorbed nutrients to the bloodstream.
The nutrients are taken out of the food while it is being digested, and going into your bloodstream, which flows around your body and feeds the nutrients to different parts of your body.
absorption of nutrients, because microvilli increase the surface area available for absorption. These cells are commonly found in the small intestine to facilitate the absorption of essential nutrients from digested food.
