Question

The scientific word for movement of food molecules into blood.

Answer 1

The food molecules are first broken down in the ileum of the intestine, by the succus entericus enzyme, or intestinal juice, and the simplest forms of carbohydrates (simple sugars), fats (fatty acids and glycerol) and proteins (amino acids) are absorbed through villi on the intestinal walls, and this process is called absorption. This goes directly to the liver, that releases the required amounts of these nutrients into the blood, and then utilized by the body, the process being called assimilation.
