Which term refers to a hollow space in the body, such as a cavity containing organs?

The term "cavity" is used to describe a hollow space in the body that contains organs. In anatomical terms, cavities are essential as they house and protect various organs and structures. For example, the abdominal cavity contains vital organs such as the stomach, liver, and intestines, while the thoracic cavity is home to the lungs and heart. Understanding cavities is crucial in health science because they play a significant role in the organization and functioning of the body's systems.

Although "sinus" and "fossa" also refer to specific types of hollows or indentations in the body, they do not encompass the broader definition of a cavity that can contain organs. Sinuses are usually air-filled spaces in the skull, while a fossa is a shallow depression or hollow in a bone. The generality and applicability of the term "cavity" make it the most accurate choice for describing any hollow space that can contain organs.
