Interacting with our environment

 How do we get information from our environment?

The sense organs detect information.

• The eyes detect light.

• The ears detect sound vibrations.

• The nose detects different odours.

• The tongue detects different tastes.

• The skin detects different textures, temperatures and pressure.

What types of reactions are there?

Involuntary reactions happen very quickly. We call them reflexes. They happen automatically.

• You blink if something comes near your eye.

• You cough and sneeze to remove germs from your body.

• It’s hot and you start to sweat.

Voluntary reactions are ones that we decide to do. They take longer.

• Your teacher asks a question and you raise your hand.

• You need your pencil, so you walk to the other side of the room to get it.

• It’s hot and you move to stand in the shade of a tree.

Body functions

Most fish are oviparous.

Fish breathe mainly through their gills. Water enters their mouths and exits through their gills.

During this process, the water passes over capillaries in the gills. The capillaries absorb oxygen and release carbon dioxide.
