The nose is the organ in charge of smell and the entrance to the respiratory system. According to a study carried out at the Rockefeller University (United States), thanks to it we are able to distinguish more than a billion different smells.
Being so visible on our face – a nose changes practically our entire physiognomy – since ancient times it has been sought to perfect it. In fact, according to some historical documents, Egyptian doctors already performed operations on the nose in 3000 BC These operations were used to rebuild the nose after a war conflict.
On the other hand, the nose is the only organ that can get tired when it perceives an unpleasant smell, as the body detects it and we become aware of it. However, after a while the brain can get used to it, something that does not happen with other senses of our body such as taste or sight.
In addition, the human being has a great olfactory memory. This is because the sense of smell is directly connected to the limbic system, the part of our brain that is responsible for regulating the body's physiological and emotional responses. Hence, we can associate certain smells with childhood or adolescence, since the nose is an organ that is closely associated with emotional memories.
