Fagosyyttisolun

Fagosyytisolun, also known as phagocytosis, is a biological process where a cell, typically a phagocyte, engulfs and engulfs a particle, such as a bacterium, cell debris, or other foreign substance. This process is crucial for the immune system's defense mechanism, as it allows phagocytes to eliminate pathogens and maintain overall health. Phagocytosis involves several steps: recognition, adhesion, internalization, and digestion. The particle is first recognized by specific receptors on the phagocyte's surface, which then adhere to the particle. The phagocyte extends pseudopodia around the particle, forming a phagosome, a membrane-bound vesicle that encloses the particle. The phagosome fuses with lysosomes, forming a phagolysosome, where digestive enzymes break down the engulfed material. The digested contents are then released back into the cytoplasm, completing the phagocytosis process. This process is essential for the body's defense against infections and the maintenance of tissue health.
