Which term refers to swelling in the body?

The term that refers to swelling in the body is "tumor," which in a medical context is used to describe an area of abnormal enlargement or swelling. This swelling can be a result of various factors, including inflammation, injury, or disease processes. It is important to note that in medical terminology, "tumor" does not always imply cancer; instead, it simply refers to a localized swelling.

Understanding the other terms can clarify their meanings in relation to the concept of swelling. "Functio laesa" refers to the loss of function that can occur in an injured or inflamed area. "Dolor" translates to pain, which is often associated with injury and inflammation, but does not directly indicate swelling. "Rubor" means redness, which can accompany swelling as part of the inflammatory response, yet it also does not specifically denote swelling itself. Therefore, while all these terms relate to the body's response to injury or disease, "tumor" specifically captures the essence of swelling.
