autoabsorption
Most nutrients enter the blood through the small intestines.
I think that would be the small intestines :)
I'm assuming you mean 'where' in the body, as opposed to 'when'. In terms of when, it happens all the time! The exchange of nutrients from food mainly happens in the intestine, though other nutrients can be absorbed elsewhere in the body sometimes. These enter your blood stream here and travel to the relevant area of your body using the circulation. Waste will enter your blood stream as well but be filtered out of your blood by your kidneys and is passed out of the body as urine.
Like most nutrients, glucose sugar is absorbed into the blood stream through the walls of the small intestine from the food one eats.
The food we eat is broken down into individual, microscopic nutrient molecules which enter the cell.

through cells in the villi of the small intestine
the nutrients enter the blood in the small intestine. The lining of the small intestine is called the villi, that is were the blood is absorbed into the bloodstream
All nutrients we have taken are absorbed into the blood in the small intestine. The excess are stored in the liver from where if required is again absorbed into the blood.

"digestive"
Nutrients from food and beverage is absorbed inside the walls of the small intestine. As we digest our food, all nutrients are taken in the small intestine and would most probably then enter our bloodstream from there on.
Most nutrients are just dissolved in the plasma of the blood. They are transported to the cells when the heart pumps the blood through arteries, arterioles and capillaries. Nutrients diffuse through the walls of capillaries and enter cells.
