After food get digested, there are enzymes that break down larger molecules such as proteins and carbohydrates into smaller molecules before it can pass into the blood stream. Mainly in the small intestine, nutrients pass into the blood stream. Depending on the type of "nutrient" that get passed through, some just diffuse through by difference in concentration gradient. Some require active pumps in the lining of the small intestine to pump the "nutrient" into the cell or blood stream. Hope I didn't confuse you too much. In short, some molecule just pass through. Some needs to be pumped across the cell membrane.

Why does the digestive system need nutrients?
The blood carries nutrients from the small intestine to all over the body. The villi in the small intestine allow nutrients from digested food to pass through the intestinal wall to the blood vessels. Then the blood carries the nutrients away.
How do your bodies deliver nutrients into the blood?
Your body delivers nutrients into the blood through the food that you eat. As food is broken down the nutrients are absorbed into the blood stream and are then carried to tissues and organs throughout the body.
When does the exchange of nutrients and waste materials?
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.
How does glucose normally enter the blood?
Like most nutrients, glucose sugar is absorbed into the blood stream through the walls of the small intestine from the food one eats.
What molecule can diffuse from the digestive tract into the human blood stream without first being digested?
Water, oxygen, and carbon dioxide can enter or leave a cell by diffusion without being digested.
Why should the food be digested system?
so that the nutrients are absorbed to the blood stream
How is digested food carried to your cells?
The digested food is in form of glucose which is broken down in mitochondria to release energy.
Which system will the digestive system work with to ensure that your body gets the nutrients from the food you eat?
When nutrients are digested they are then absorbed into the blood stream. The cardiovascular system then distributes those nutrients to the different areas of the body that are in need of them.
What is the liquid part of the blood that carries nutrients from digested food?
The liquid part of the body that carries nutrients from the digested food is plasma.
What nutrients need to be digested before they are taken into blood?
yu
How does the digested food reach the body cells?
Nutrients are carried by the blood.
The process in which blood capillaries pick up digested nutrients is?
absorption
What nutrients are digested in the small intestine?
The small intestine is where nearly all of the nutrients are digested. The stomach breaks down the food into a liquid and the colon absorbs water.
If you have just eaten food where will your blood go?
After eating, food is digested in your stomach and then passed through your small intestine. Nutrients are absorbed through the walls of the small intestine and into your blood stream, where it is carried to cells needing nutrients. Whatever food left over is waste and it is passed out of your body.
Do nerves absorb nutrients into the bloodstream?
Digested molecules of food, water and minerals from your diet are absorbed from the cavity of the upper small intestine absorbed materials cross the mucosa into the blood stream and are carried off in the blood stream to other parts of the body for storage or further chemical changes process varies with different types of nutrients example proteins and carbohydrate's.
Is blood a veg or non veg?
Blood is not related to vegetables. However, vegetables after eaten and digested, go to the blood stream.
The movement of nutrients into the bloodstream?
Absorption is the process by which nutrients are moved into lymph and blood.
