Remember this:

The basic unit of life is the cell. It's very small and it's a living thing. Blood cells are flat an circular.

Blood cells: they carry oxygen from the lungs. 

The basic life processes are three:

• Nutrition
• Interaction
• Reproduction

We have different systems in our bodies like: the respiratory system, the muscular system, the excretory system or the reproductive system.

We also have five senses that help us to interact with our environment. Those five senses are: smell, sight, touch, taste and hearing.
