fagositere

Fagositere is a term used in immunology to describe the process by which certain cells, known as phagocytes, engulf and digest foreign particles, such as bacteria, viruses, or cellular debris. This process is crucial for the body's defense mechanism against pathogens and for maintaining overall health. Phagocytes, including macrophages and neutrophils, are specialized cells that play a vital role in the immune response. They recognize and bind to foreign particles through specific receptors on their surface. Once bound, the phagocyte extends pseudopodia, which surround and engulf the particle, forming a phagosome. The phagosome then fuses with a lysosome, creating a phagolysosome. Within this acidic environment, enzymes break down the engulfed material, allowing the phagocyte to digest and eliminate the foreign particle. This process helps to clear infections and prevent the spread of pathogens throughout the body. Fagositere is an essential component of the innate immune system, providing a rapid and non-specific response to potential threats.
