What is phagocytis?

Answer 1

Phagocytosis is when a cell engulfs a large foreign object into the cell and then introduces lysosomes to this foreign objects. The best example is the immune system, where T cells will engulf harmful bacteria, etc, into themselves so that they will not harm the host.

Answer 2

In unicellular creatures, phagocytosis is a critical mechanism for nourishment; in multicellular organisms, it is a function of specialized cells called phagocytes. The process of phagocytosis entails the recognition and ingestion of particles larger than 0.5 m into a vesicle formed by the plasma membrane known as a phagosome. Importantly, phagocytes can also eat apoptotic cells in addition to microbial infections. They assist in clearing out the daily turnover of billions of cells in this way. Thus, phagocytosis becomes crucial for maintaining tissue homeostasis as well as the removal of microorganisms.

Answer 3

Phagocytosis is the process in which cells engulf and digest foreign particles, such as bacteria, viruses, and debris. This is a key mechanism of the immune system to eliminate pathogens and maintain tissue homeostasis. Impaired phagocytosis can lead to increased susceptibility to infections.
