Detailed explanation-1: -The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes.
Detailed explanation-2: -The chemicals also attract white blood cells called phagocytes that “eat” germs and dead or damaged cells. This process is called phagocytosis. Phagocytes eventually die.
Detailed explanation-3: -Phagocytes release digestive enzymes which break down the trapped microbes before they can do any harm. This process is called phagocytosis.
Detailed explanation-4: -Phagocytes are a type of white blood cell that use phagocytosis to engulf bacteria, foreign particles, and dying cells to protect the body. They bind to pathogens and internalise them in a phagosome, which acidifies and fuses with lysosomes in order to destroy the contents.
Detailed explanation-5: -Phagocytes degrade pathogens through phagocytosis, which involves engulfing the pathogen, killing and digesting it within a phagolysosome, and then excreting undigested matter.
