From theCambridge English Corpus If a foreign object is larger than approximately 10 /jm in diameter, encapsulation rather thanphagocytosisoccurs. From theCambridge English Corpus The central piece of this defensive system is the monocyte/macrophage, which plays dual functional roles in regulating cytokine production andphagocytosis.
