2. The five senes

Our five senses receive information from the world. They are important for interaction.

2.1. Sight

  • Light enters our eye through the cornea and the pupil.
  • The iris controls the amount of light. If there is a lot of light, it becomes small.
  • The lens focuses the light.
  • The image is proyected on the retina. It is connected to the optic nerve.
  • The optic nerve sends the information to the brain.


2.2. Hearing

  • Sound waves enter the ear through the auditory canal and the eardrum vibrates.
  • The vibration moves the three small bones. They transmit this vibration to the cochlea.
  • The cochlea transforms the sound into electrical signals that travel to the brain through the auditory nerve.


2.3. Smell and taste


2.3.1. Smell
  • The air enters the nose through the nostrils.
  • Nerve receptors send the information to the brain.


2.3.2. Taste
  • When we eat, receptor on our tongue (called "buds") detect the different tastes. 
  • This information is sent to the brain through different nerves.

2.4. Touch
  • The dermis contains nerves that detect sensations: temperature, pain, texture, etc. This information is sent to the brain.

The main structrures are called organelles.

Parts of a cell:
-        Nucleus : it controls the cell. It contains the DNA(AND)
-        Cytoplasm: it´s like a jelly liquid that fills the inside of a cell. It holds the organelles.
-        Vacuole: it has water and minerals inside
-        Cell membrane: it´s the outside wall of the cell
-        Mitochondrion: It produces the energy of the cell.

And also in plants:
-Chlorosplast: it makes the photosynthesis

-Cell wall: it is the first outside wall of the cell
