Fagocitózó

Fagocitózó is a biological process where a cell engulfs a large particle. This particle can be a microorganism, a foreign substance, or a dead cell. The term "fagocitózó" originates from Greek words, meaning "to eat" and "cell". The process is carried out by specialized cells called phagocytes, which are a type of white blood cell in animals.

During fagocitózó, the phagocyte extends its cell membrane to surround the particle. This forms a pocket within the cell, enclosing the particle in a structure called a phagosome. The phagosome then fuses with lysosomes, which are organelles containing digestive enzymes. These enzymes break down the engulfed particle into smaller molecules that the cell can then absorb or excrete.

Fagocitózó plays a crucial role in the immune system, defending the body against infections by eliminating pathogens. It is also essential for tissue repair and homeostasis, as it removes cellular debris and dead cells. In some organisms, like amoebas, fagocitózó is a primary method of feeding. The efficiency and regulation of fagocitózó are vital for maintaining health.
