The pharynx is part of both the [[Cardiorespiratory System - Anatomy & Physiology|respiratory]] and [[Alimentary System Overview - Anatomy & Physiology|digestive]] system. Both systems have entrances to the pharynx but they are separated from each other by the [[Soft Palate|soft palate]].

During exercise or during respiratory distress, the mouth can be used as an additional opening of the respiratory system and then the [[Oral Cavity - Oropharynx - Anatomy & Physiology|oropharynx]] also becomes an air-way.

The pharynx can be split into different regions- the [[Oral Cavity - Oropharynx - Anatomy & Physiology|oropharynx]], [[Larynx - Anatomy & Physiology#Laryngeal Pharynx|laryngeal pharynx]] (sometimes referred to as the oesophageal pharynx) and the [[Nasopharynx - Anatomy & Physiology|nasopharynx]]
