During digestion, where is digested food absorbed into the blood stream?
pancreas |
|
large intestine |
|
stomach |
|
small intestine |
The small intestine is where most digestion takes place. As food travels along the small intestine it gets broken down completely by enzymes secreted from the walls. These enzymes are produced in the small intestine as well as in the pancreas and liver. After the enzymes break down the food, the resulting substances are then absorbed into the blood via capillaries in the small intestine walls.
