Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat' and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome. It is one type of endocytosis. A cell that performs phagocytosis is called a phagocyte.
For example, phosphatidylserine is an "eat-me" signal that, when exposed on the surface of a cell, triggers phagocytes (i.e. cells that eat other cells) to eat that cell. Phosphatidylserine is normally found on the inside of healthy cells, but can become exposed on the surface of dying, activated or stressed cells.
Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested materials. Endocytosis includes pinocytosis (cell drinking) and phagocytosis (cell eating). It is a form of ...
Human cannibalism is the act or practice of humans eating the flesh or internal organs of other human beings. A person who practices cannibalism is called a cannibal . The meaning of " cannibalism " has been extended into zoology to describe animals consuming parts of individuals of the same species as food.
Phagocytosis, also known as cell eating, is the absorption of larger particles such as bacteria into the cytosol. In smaller single-celled organisms, this is how it feeds. In larger multicellular organisms, it is a way of destroying old or damaged cells or ingesting microbial invaders.
In addition to aiding in Gosselin’s weight loss, he told the outlet that the drug helped with other aspects of his life, including forming better eating habits as well as giving up alcohol.
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible.
