               THE SMELL
Hello, today I am going to talk about the nose.
The smell is one of the sense that humans have.
The nose is the organ of smell. The human nose can percibe more than 10.000 different smellies. The receptor of the smell is in the pituitary gland that is inside the nortrils. We can smell good things like a perfume or bad things like rotten fish . Do you know that the snots are the smoke of the cars? 

THE RESPIRATORY PROCESS        1

1. When we breath, the air passes to our nose. 
2. Then the air goes down to our lungs.
3. Later we expel the carbon dioxide with the mouth . 2                                                                    

  












              YOU CAN LOOK THE NOSE IN TWO FORMS:

1. From out it has five parts: dorsum, tip, alae, nostril and columella.
2. From inside it has five parts: oftaculary bulb, nasal cavity, nostril, hard palate and soft palate.

                          ANIMALS' NOSE

• The dog nose smells more things that the human nose. And that is the reason why the dogs have the nostrils very big.
• The African elephants can  smell  five times more than the human  and the double than the dogs.
•  The elephants use their sense to look for food and to identify members of the family.
•  A good use of the animals smell is to find food, companions and to avoid predators.
•  Maybe that is the reason why the elephants have survived many years.
