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.

ETHICS :
Ethics or moral philosophy is a branch of philosophy that "involves systematizing, defending, and recommending concepts of right and wrong behavior".The field of ethics, along with aesthetics, concerns matters of value, and thus comprises the branch of philosophy called axiology.
Ethics seeks to resolve questions of human morality by defining concepts such as good and evil, right and wrong, virtue and vice, justice and crime. As a field of intellectual inquiry, moral philosophy also is related to the fields of moral psychology, descriptive ethics, and value theory.
Three major areas of study within ethics recognized today are:
1. Meta-ethics, concerning the theoretical meaning and reference of moral propositions, and how their truth values (if any) can be determined
2. Normative ethics, concerning the practical means of determining a moral course of action
3. Applied ethics, concerning what a person is obligated (or permitted) to do in a specific situation or a particular domain of action.
MORALS :
A moral (from Latin morālis) is a message that is conveyed or a lesson to be learned from a story or event. The moral may be left to the hearer, reader, or viewer to determine for themselves, or may be explicitly encapsulated in a maxim. A moral is a lesson in a story or in real life.
