Increased warmth is referred to by which medical term?

Increased warmth is referred to by the medical term "calor." This term originates from Latin, where it means "heat." In the context of inflammation or infection, increased warmth is one of the classic signs, often alongside redness, swelling, and pain, which are collectively referred to as the signs of inflammation.

When the body encounters injury or infection, inflammatory mediators stimulate increased blood flow to the affected area, which in turn raises the temperature locally – thus, "calor." This response is part of the body's natural defense mechanism aimed at facilitating healing and fighting off pathogens.

The other terms presented do not relate to the concept of increased warmth. Epistaxis refers to nosebleeds, conjunctivitis is an inflammation of the conjunctiva often causing redness and irritation of the eye, and URI stands for upper respiratory infection, which does not specifically address increased warmth in a physiological or localized context. Understanding these terms helps to enhance clinical knowledge in medical settings, especially when assessing signs and symptoms in patients.
