Nutrients are absorbed through the walls of the small intestine into the bloodstream by diffusion or active transport. The structures in the walls of the intestine that allow this to happen are villi, which resemble finger-like projections. They are very well adapted to absorbing nutrients, thanks to a huge surace area, thin cell walls to make diffusion more efficient, and a rich blood supply to keep a strong concentration gradient.
Small intestine is where the food enters the blood.

Large Food Molecules in The Small Intestine!
Most digestive food enters the bloodstream through the small intestine. The small intestine is where the majority of nutrient absorption takes place, as the walls of the small intestine are lined with tiny finger-like projections called villi that help absorb nutrients from digested food.
the food becomes nutrients and undigested food becomes a waste............... :D
When the food reaches the small intestine the nutrients are absorbed into the blood through the intestine wall and then the food that was not digested goes to the large intestines where water is absorbed then it is excreted
Food is absorbed into the blood primarily in the small intestine, specifically in the lining of the small intestine where the villi and microvilli are located. These structures increase the surface area for absorption of nutrients like sugars, amino acids, and fatty acids into the bloodstream.
