Nutrients cross the intestine wall
Open to everyone until Friday, October 2
To keep it, print it while it is open.
Digested food is broken into tiny nutrients inside the small intestine. These nutrients pass through the intestine wall and enter the blood.
In the picture
- The small intestine wall: its inner surface has tiny folds that nutrients can pass through.
- A nutrient particle: it moves from the inside of the small intestine through the wall.
- A blood vessel: it collects the nutrient and carries it away in blood.
Examples
- Sugar from a piece of bread entering the blood after digestion.
- Amino acids from an egg entering the blood after digestion.
Key takeaways
- The small intestine wall lets nutrients move from digested food into the blood.
- Blood then transports nutrients to the rest of the body.
