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
increase intestine surface area for more efficent absorption of digested nutrients
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
The lumen is the cavity where digested food passes through and from where nutrients are absorbed, in the small intestine.
Assimilation is the use of digested and absorbed materials to make new body parts.
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 is the process that takes nutrients through the small intestine wall. These nutrients then enter the circulatory system, which carries the nutrients to all body cells.
