Phagocytosis - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Last updated

Phagocytosis is a process used by cells such as phagocytes, to engulf and digest harmful particles, bacteria, or dead or dying cells. This process plays a vital role in the immune system by removing pathogens and debris. During phagocytosis, the phagocyte surrounds the target, encloses it in a vesicle, and then breaks it down using enzymes. This helps protect the body from infection and keeps tissues healthy.
