How nutrients and water are transported in the human body.

At the end of this lesson...

... I know the 7 main nutrients and their functions.

.... I can describe how water and nutrients from food travel through the body.

What are nutrients?

Nutrients are ... 

... important substances that living things use to stay alive and healthy.

Transporting nutrients

Food is broken down into smaller pieces in the mouth. 

It then moves down the oesophagus into the stomach.

During digestion, the small intestine absorbs the nutrients from food and passes them into the bloodstream.

Transporting nutrients and water

Water and nutrients from food are transported around the body to where they are needed.
Our blood absorbs water and nutrients from food. This travels, along with oxygen, to different parts of the body through blood vessels. Our muscles use the nutrients and oxygen all the time, even more so when we are active.
