What does engulfing mean in scientific term?

In scientific terms, "engulfing" refers to the process by which a cell or organism surrounds and internalizes a substance, typically through mechanisms like phagocytosis or endocytosis. This process allows cells to ingest larger particles, such as pathogens or debris, and is crucial for immune responses and nutrient uptake. Engulfing is an essential function in various biological contexts, including cellular maintenance and the immune system's defense against infections.
