Phagocytosis is a process by which certain cells engulf and digest particles or other cells. It is an important mechanism for the immune system to remove foreign invaders and cellular debris from the body.
Phagocytosis is carried out by specialized cells called phagocytes, which include white blood cells such as macrophages and neutrophils. The process involves several steps:
Phagocytosis plays a critical role in the body's defense against pathogens, as well as in the removal of dead or damaged cells. It helps to maintain tissue homeostasis and prevent the spread of infections.
Here are some key points to remember about phagocytosis:
Understanding the process of phagocytosis is crucial for grasping the functioning of the immune system and its role in maintaining overall health.
