What is rubor in pathology?

Rubor is a Latin term used in pathology to describe the redness or inflammation of a tissue or organ. It is one of the classic signs of inflammation, along with calor (heat), tumor (swelling), and dolor (pain). Rubor is caused by increased blood flow to the affected area, leading to dilation of blood vessels and accumulation of red blood cells. It is often seen in response to injury, infection, or other inflammatory processes.
