inn [45]

Answer:

b- Se hacen más anchos.

Explanation:

Los conductos o vasos linfáticos son tubos que transporta tanto al líquido linfático (linfa) como glóbulos blancos que fluyen a través del sistema linfático. Estos conductos se inician en el intersticio y terminan en conductos de mayor tamaño que desembocan en la base del cuello, entre las venas yugular interna y la subclavia. A medida que va entrando en los tejidos, los conductos linfáticos se van haciendo cada vez más angostos y finos, convirtiéndose finalmente en capilares linfáticos, donde las sustancias que no pueden penetrar los vasos sanguíneos son recogidas por estos capilares.
