Summary:

It was always thought that olfactory receptors' sole bodily function was to smell, and could only be found inside a nose. But now a new study has found two olfactory receptors in human lung tissue.

It was always thought that olfactory receptors' sole bodily function was to smell, and could only be found inside a nose. But now a new study, published in Frontiers in Physiology, has found two olfactory receptors in human lung tissue.

And when the researchers from Ruhr-University Bochum in Germany activated these receptors, they found that they regulated the way in which the airways smooth muscle cells contracted.

Contraction of smooth muscle changes the size of our airways, suggesting that this research may open new avenues for treating chronic breathing disorders -- such as asthma, emphysema and bronchitis -- that constrict and obstruct the airways.

Not surprising, even blind folks have special receptors that allow them to sense certain wavelengths of light
