What is signified by the root "gastr/o"?

The root "gastr/o" specifically refers to the stomach in medical terminology. This is derived from the Greek word "gaster," which means stomach. In the context of medical language, understanding the roots of words helps in deciphering their meanings, especially in anatomy and healthcare.

When examining the choices, "skin" is represented by roots such as "derm" or "cutane," while "intestines" are indicated with terms like "enter/o." The root for "head" is often "cephal/o" in medical terminology. Therefore, "gastr/o" is distinctly linked to the stomach, making it the correct choice in this scenario. Knowing these roots can greatly aid in comprehending and communicating medical concepts accurately.
