Dr. Peter Heberle of the Research Institute for food chemistry found a rather interesting phenomenon. It turns out that the person is able to distinguish between the odors not only the nose, but also the heart, lungs and even the blood.
According to researchers, the greatest number of odor molecules first enters the stomach, and only then through the blood to reach other internal organs. That is why the human nose can distinguish only a small portion of the smells that surround it. In addition, scientists from the United States failed to prove that blood cells also have receptors of smell, as they respond to odors.
During the experiment it was also proven that the heart and lungs also serves the response to different odors, simply, scientists still unclear what the mechanism of this phenomenon. They put forward the hypothesis that the response to odors from the internal organs can be regarded as one of the parts of the body at the sight of delicious food. For example, it is known that coffee has more than 1000 elements, which constitute the smell of it, but man is able to perceive only 25. The rest of the full perception of the drink happens only when it enters the body.
