The English term "internal organs" refers to the organs inside the body, such as the heart, lungs, liver, and intestines. In Japanese, the most common and general term is 内臓 (naizō). However, depending on context—such as medical, culinary, or traditional medicine—other terms like 臓器 (zōki) or 五臓六腑 (gozō roppu) may be used.
