Final answer:
In phagocytosis, digested contents are eliminated by exocytosis, after the engulfed material is broken down by enzymes within the lysosomes of phagocytes.
Step-by-step explanation:
In phagocytosis, digested contents are eliminated through a process called exocytosis. Phagocytosis is often described as cellular 'eating' and is employed by immune cells like phagocytes and neutrophils to engulf and remove invading pathogens.
The process includes several steps: a foreign particle such as a bacterium is first engulfed by a phagocyte to form a phagosome, which fuses with a lysosome to become a phagolysosome, where the particle is digested using hydrolytic enzymes. The final step involves the expulsion of undigested materials from the cell, completing the process of phagocytosis.
