Olfaction

Hello folks, now is time for another blog and today’s topic is about the human body, everybody knows that the human body is like a perfect machine, there is a lot of process that happen in the human body, just for say something: the digestion, the cellular respiration, the excretion of non-useful substance etc. all necessary to keep us alive, in other words the human body is amazing.  Well I have to write about only one subject of our body, and I choose the sense of smell: The Olfaction

The Olfaction is a chemical sense, in the nose we can find hundreds of receptors, each binding to a specific molecular texture. When we got a molecule in our nose some receptor are more excited than others, this combination of excitatory signals determined the smell of the molecule, this signals are processed by the olfactory system then the brain translate this in the sense of the smell.

That’s all the “science” behind the olfaction (in a very simpler way), to me is a really amazing sense, most people prefer other like the sight or the hearing, because are really useful and essential to have a normal life, but the smell let us enjoy the little details of a perfect situation : the smell of the beach, of the forest, of someone you love etc. the smell of something we like, can makes us happier.
