Absorption and Assimilation

So once you eat your food, how does the body extract the ingredients that it requires? Would you be surprised to know that this function actually happens in your small intestine? The process is known as Absorption and Assimilation. Let us learn about it here.

Absorption and Assimilation

As the food gets broken down into smaller and simpler particles, it has to get absorbed into the bloodstream. It is only through the blood and circulatory system that the digested food reaches various cells and tissues. Blood coming from the digestive organs carries simple sugars, glycerol, amino acids, and a few vitamins and salts to the liver. The liver stores and processes these substances. They are also detoxified here. It delivers the nutrients to the rest of the body, as and when needed. This entire process is summed up as Absorption and Assimilation.

The process through which the end products of digestion are absorbed into the blood or lymph from the intestinal mucosa is called as Absorption. This process occurs either by the passive, active or facilitated transport mechanisms in the body. The small intestine is the organ where absorption occurs. It is specially adapted to carry out this function.
