Answer:
The CORRECT order is: 3, 5, 1, 4, 2. "A foreign cell is surrounded by the cell membrane of the phagocyte and contained within a vesicle. A lysosome fuses with the vesicle containing a foreign cell. Lysosomal enzymes break down the foreign cell, and the wastes from the foreign cell are removed".
Explanation:
When a cell called phagocyte is going to incorporate a new solid substance, such as a bacteria, the process involved is called phagocytosis. Phagocytosis is a function of specialized immunological system cells that are capable of removing strange bodies from the immune system as a first natural defense line. The membrane of the phagocyte invaginates and surrounds the strange body, which is trapped and included in an endocytic vesicle called phagosome. This vesicle often fusses a lysosome which liberates its enzymes into the phagosome. These enzymes are in charge of digesting or destroying the strange content. After that, the produced wastes are removed from the cell.
