MICROANATOMY

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. Phagocytes eventually die. Pus is formed from a collection of dead tissue, dead bacteria, and live and dead phagocytes.

Detailed explanation-2: -Another function of phagocytosis in the immune system is to ingest and destroy pathogens (like viruses and bacteria) and infected cells. By destroying the infected cells, the immune system limits how quickly the infection can spread and multiply.

Detailed explanation-3: -Phagocytosis is an important process for nutrition in unicellular organisms, while in multicellular organisms it is found in specialized cells called phagocytes. Phagocytosis consists in recognition and ingestion of particles larger than 0.5 m into a plasma membrane derived vesicle, known as phagosome.

Detailed explanation-4: -Within the phagocyte the pathogen is held in a vesicle known as a phagosome. Lysosomes, organelles within the phagocyte, will then fuse with this phagosome. They release enzymes known as lysozymes which will hydrolyse the pathogen, destroying it.

Detailed explanation-5: -Hemolysis is the medical term used to describe the destruction of red blood cells.
