- The organ that digests food into smaller pieces is the stomach.
- Also known as carbohydrates is sugar.
Circulatory System
- This is the pump that pushes blood around the body is the heart.
- There are three types of these that carry blood around the body. Blood vessels
- These carry blood away from the heart are arteries.
- These carry blood towards the heart are veins.
Random
