In a normal human being, the process of micturition requires both the voluntary and involuntary nervous system components.

Answer:
The answer to fill in the blanks, for this statement: The pharynx is the common passageway for food and air that leads into these two inferior structures: the esophagus and the larynx.
Explanation:
The pharynx, even though being a pretty simple structure of a tube that runs from both nose and mouth towards the throat and bifurcates into the esophagus and also the larynx, is one of the few organs that works both for feeding and also breathing. The pharynx is divided into three portions: the nasopharynx (the back of the nasal cavity), oropharynx (the back of the mouth) and the laryngopharynx. Because it is the only tube-like structure that leads both from the nose and from the mouth, it serves as the conducting system for both food and fluids, and air. When it reaches the neck, around the epiglotis, the pharynx transforms into the larynx, through which air passes towards the lungs. On the other side, the pharynx gives way to the esophagus, which is the main conducting system for food and fluids.
