How do nutrients get assimilated after digestion in the human body
Answers
Explanation:
Assimilation is the movement of digested food molecules into the cells of the body where they are used. For example: glucose is used in respiration to provide energy. amino acids are used to build new proteins.The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.
Answer:
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.
