Nervous System
The nervous system consists of sensory organs, nervous pathways and processing centres. The nervous system allows us to interpret the information that we receive and transform it into some kind of response. The nervous system is divided in the central nervous system and peripheral nervous system.
Investigate Reaction Time
1. Place your fingers one inch apart and have someone hold a ruler between your fingers.
2. Catch the ruler with your fingers as soon as you see it falling.
3. Then look at the ruler and measure how far the ruler fell in inches.
Digestive System
The food we eat has to be broken down into other substances that our bodies can use. This is called digestion. Without digestion, we could not absorb food into our bodies and use it.
Digestion happens in the digestive system, which begins at the mouth and ends at the anus.
After we swallow, our food passes through these organs in turn: oesophagus or gullet, stomach, small intestine and large intestine.
