Macrófago

Histiocito

Definición

Es un tipo de célula inmunitaria. Destruye sustancias extrañas para proteger al cuerpo de una infección.

Información

Los macrófagos no viajan a través de la sangre. En lugar de esto, permanecen en una parte del cuerpo.

Los macrófagos se encuentran en muchos órganos y tejidos, entre ellos los siguientes:

Cerebro
Tejido mamario
Hígado
Pulmón
Ganglios linfáticos
Placenta
Bazo
Amígdalas

En las personas que tienen una enfermedad llamada histiocitosis de las células de Langerhans (anteriormente llamada histiocitosis X), hay un exceso de macrófagos y otros glóbulos blancos en algunos tejidos corporales.
