The Body as a Whole Practice Test

Viscera denotes the soft internal organs housed within the body's cavities. It’s the collective term for the organs inside the body, such as the heart, lungs, liver, stomach, intestines, and kidneys. The womb is just one organ (the uterus) and isn’t the general term for internal organs. “Organs” is a broad category that includes many structures, while “organ systems” are groups of organs that work together. Since the question asks which term refers to the viscera, the appropriate term is viscera. (Note: the singular form is viscus when talking about one internal organ.)
