Science
Your nose isn't the only part of your body that can recognize different smells. Such sensors are located in our heart, lungs and even blood, scientists say.
Researchers from the Technical University of Munich and the German Research Center for Food Chemistry conducted a number of experiments and came to the conclusion that cells of various organs also have the ability smell.
When chemical compounds from food and other substances enter the nose, they bind to olfactory receptors to tell our brains about the smell.
Previously, it was believed that such receptors were found only on the mucous tissues of the nose, but the study showed that other organs also have them.
When scientists placed blood cells in a container with an aromatic chemical compound, the cells moved to the source of the smell.
It is known that sperm cells also contain odor receptors, which help them find an egg. Now we have found out that such receptors are found in the heart, lungs and blood.
