Ants are eusocial insects of the family Formicidae /fÉrËmÉªsÉ¨diË/ and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants.ome arthropod species spend part of their lives within ant nests, either preying on ants, their larvae, and eggs, consuming the food stores of the ants, or avoiding predators. These inquilines may bear a close resemblance to ants.
The pharynx is the body cavity that connects the nasal and oral cavities with the larynx and esophagus. It is commonly referred to as the throat. The pharynx is part of both the digestive and respiratory systems. For the digestive system, its muscular walls function in the process of swallowing and it serves as a pathway for the movement of food from the mouth to the esophagus.
Function of the Pharynx in the Respiratory System. Aside from its work for the digestive system, the pharynx also plays a supporting role for the respiratory system. Just like the passage of food, the pharynx also acts as the passage of air. Once air is inhaled from the nose or the mouth, the pharynx will then direct it towards the larynx down to the trachea.
