The organ at the back of the mouth that both air and water can pass through is the pharynx. It serves as a pathway for both air to enter the lungs and for food and liquids to pass into the esophagus.
Jacobson's organ in snakes is a chemosensory organ located in the roof of their mouth. It helps snakes detect and analyze chemical substances in their environment by flicking their tongues to collect samples and transferring them to the organ. This allows snakes to effectively locate prey, mates, and navigate their surroundings.
As with most creatures the feeding organ of an earthworm is the mouth. Located behind the mouth is the pharynx which acts as a suction pump; its muscular walls draw food back.
The pharynx is a shared pathway for both air from the nose and mouth leading to the larynx (air passage), and food from the mouth leading to the esophagus (food passage). This intersection allows for proper functioning of both respiratory and digestive systems.

Jacobson's Organ
The organ responsible for mixing food in the mouth and initiating swallowing is the tongue. It helps move food around in the mouth to mix it with saliva and then pushes the food to the back of the mouth to start the swallowing process.
The fauces are the narrow passage at the back of the mouth that connects the mouth to the pharynx. It serves as a gateway for food and air to pass through.
The tongue is the muscular organ responsible for initiating deglutition, or swallowing. It helps to move food towards the back of the mouth and into the pharynx, which then triggers the swallowing reflex.
