Humoral factor
Humoral factor (pronunciation: hyoo-mor-al fak-tor) is a term used in medicine and biology to refer to substances such as hormones, antibodies, or cytokines that are secreted into the bloodstream and influence the function of cells or tissues.
Etymology
The term "humoral" is derived from the Latin word "humor", which means "fluid". This is a reference to the ancient humoral theory of medicine, which posited that the body was governed by four "humors" or fluids. The term "factor" comes from the Latin "factor", meaning "doer" or "maker", and in this context refers to the active role these substances play in the body's function.
