Correct Answer » B Explanation |

Ans: b. Emperipolesis
(Refi Robbins and Cotran Pathologic Basis of Disease 9th edn; Page no. 840)
- Emperipolesis is the active penetration of one cell by another which remains intact.
- It differs from phagocytosis in that an engulfed cell exists temporarily within another cell and with an intact normal structure while in phagocytosis, the engulfed cell is destroyed by the protective action of lysosomal enzymes.
