fagocitózissal

Fagocitózis is a process by which certain cells, known as phagocytes, engulf and digest foreign particles, such as bacteria, cell debris, or other unwanted substances. This process is crucial for the immune system's ability to defend the body against infections and maintain overall health. Phagocytes, including neutrophils, macrophages, and dendritic cells, recognize and bind to foreign particles through specific receptors on their surface. Once bound, the phagocyte extends pseudopods, which surround and enclose the particle, forming a phagosome. The phagosome then fuses with lysosomes, which contain digestive enzymes, to form a phagolysosome. Within the phagolysosome, the foreign particle is broken down into smaller components, which are then recycled or excreted by the cell. Fagocitózis is a fundamental mechanism in the innate immune response and plays a vital role in protecting the body from various pathogens and maintaining tissue homeostasis.
