Basophils

Basophils (pronounced: /ˈbæsəˌfɪlz/) are a type of white blood cell that play a crucial role in the immune system. They are the least common of the white blood cells, representing about 0.5% to 1% of the total white blood cell count in the blood.

Etymology

The term "Basophil" comes from the Greek words "basis" which means "base" and "philos" which means "loving". This is because basophils are attracted to basic (alkaline) dyes.

Function

Basophils are part of the immune response and are responsible for releasing chemicals such as histamine and serotonin that help to dilate blood vessels and attract other immune cells to the site of an infection or injury. They also play a role in allergic reactions and asthma.
