Ability To Smell
The horse's olfactory receptors are located in the mucosa of the upper nasal cavity. Due to the length of the nasal cavity, there is a large area of these receptors, and the horse has a better ability to smell than a human. Additionally, the horse also has a vomeronasal organ, or Jacobson's Organ, which is in the hard palate, and is able to pick up pheromones and other scents when a horse exhibits the flehmen response. The flehmen response forces air through slits in the nasal cavity and into the vomeronasal organ. Unlike many other animals, the horse's Jacobson's Organ doesn't open into the oral cavity.

“But, when nothing subsists from a distant past, after the death of others, after the destruction of objects, only the senses of smell and taste, weaker but more enduring, more intangible, more persistent, more faithful, continue for a long time, like souls, to remember, to wait, to hope, on the ruins of all the rest, to bring without flinching, on their nearly impalpable droplet, the immense edifice of memory.”
—Marcel Proust (1871–1922)
