A cat’s nose can act as a chemical analysis kit



A cat’s nose consists of a group of Tightly coiled bony structures in the airways and that it has similarities to a piece of chemical analysis equipment called a parallel spiral gas chromatography.

The authors of the published study PLoS Computational Biology They analyzed the function of this complex nasal structure in cats, using computer simulations that provide new insights into mammalian evolution.

Coordinated study Ohio State University (USA), indicates that the convoluted nasal structures of cats function in a similar manner to the parallel spiral gas chromatograph, which is laboratory equipment used for high-efficiency analysis of the chemical composition of substances.

The team saw that, in the case of cats, the air parted two streams of flow, One that cleans and moisturizes and another that quickly and efficiently carries the scent to the sniffing area.

Chromatography too detection and separation of chemicals in vaporized form, Moreover, the efficiency of the underlying technology is increased by the use of multiple tubes branching from a high-velocity gas stream.

If a cat’s nose only has a straight tube for scent detection, it must be longer than the physical size of the head allows As effective as it looks in reality.

These findings deepen our understanding of how they allow the development of more complex channels MammalsThe study indicates that cats, in particular, work to improve the sense of smell.

The researchers note that the evolutionary presence of convoluted olfactory ducts in mammalian noses is remarkably similar to another sensory organ, the snail-like coiled cochlea, which is also unique to mammals.
