Theories about purring
We said earlier that the feline purr is a sound which its origin is still unknown true and the emission mechanism.
There are two scientific theories about it: Electromyographic studies support the hypothesis that they are the muscles of the larynx of the cat, that shaking fast cause a dilatation of the glottis and its immediate regression, whose fast activity causes some vibrations when inhaling and exhaling the air when breathing. All this physical mechanics causes the purr.
The other theory holds that this sound is of hemodynamic origin. This hypothesis states that the purr originates in the posterior vena cava. Specifically at the height of the diaphragm, since the muscles compress the blood flow, causing vibrations that are transmitted through the bronchi.
