* Fluid-borne, less volatile chemicals enter the vomeronasal organ through the [[Alimentary_-_Anatomy_%26_Physiology#Oral_Cavity|oral cavity]] by means of nasopalatine (incisive) ducts.

* Some [[Reproductive_Behaviour_-_Attractivity_Behaviour_-_Anatomy_%26_Physiology#Pheramones|pheromones]] are less volatile and need to be detected by the '''vomeronasal organ'''.
* Some [[Attractivity Behaviour - Anatomy & Physiology#Pheramones|pheromones]] are less volatile and need to be detected by the '''vomeronasal organ'''.

* Male closely approaches the source of [[Reproductive_Behaviour_-_Attractivity_Behaviour_-_Anatomy_%26_Physiology#Pheramones|pheromones]] and will nuzzle the female genital region.

* Curling of the upper [[Lips_-_Anatomy_%26_Physiology|lip]] closes the '''nostrils''' and allows negative pressure to form in the '''nasopalatine duct'''.

* Flehmen behaviour allows less volatile pheromones to be examined by sensory neurons in the '''vomeronasal organ'''.

* As in the males, females will display flehmen to novel compounds such as fluids associated with the [[Gestation -Placenta - Anatomy & Physiology|placenta]],newborn animals and other volatile materials.
