Phagocytosis occurs in a process of ingestion and destruction of solid particles in the body through cells, these cells receive substances called assets and liabilities, responsible for transporting the same.
Let's get to know a little bit about the phagocytosis process?
Phagocytosis has as its main objective to enclose solid particles into its interior. important parts of our body are protected, preventing invasion of bacteria, or other agents that can cause some kind of disease.
Phagocytosis may have cells inside that do not contain the power of agent substances for the active and passive transport of cells, therefore, need to find another way to carry out the process of penetration of particles, whether solid or liquid, this action has as its main function the defense, or even food, of the cell, which can be called indocytosis or penocytosis.
Indocytosis is a present type of Phagocytosis, to make it clearer, indocytosis is the key for the cell to be able to capture particles solid, this capture can be called, according to biology, cytoplasmic or pseudopod extensions (expansion of the plasma membrane), with this process, the cell manages to come into contact with the solid part, thus emerging a kind of engulfment of particles, these particles after this path taken by the cells, they end up being part of the cytoplasmic structure of the cells, surrounded by a membrane, which we can call the Phagosome.
The phagosome is a structure of a pouch in which the membrane particle is deposited for a certain period, this pouch binds to the lysosome, which are organelles released through a process of releasing enzymes from the phagosome itself, this release happens to eliminate cell debris and microorganisms, the The connection of both forms the digestive vacuole, as the name suggests, digestion process, this junction reuses cell material, giving vitality to the same
During this somewhat complex process, it can occur along the way that some materials are not digested, receiving the name of residual bodies, which soon after, are excreted by the cell+ Observe how the phagocytosis scheme is done in the image that Follow:
Phagocytosis does not happen alone, it needs some important cells to take place, we have the amoeba, which is a protozoan, acting as a fundamental part in the nutrition of these beings, through the capture of foods.
In addition to the amoeba, there is also:
They are leukocyte blood cells, in addition to that there are 5 more cells (Cosinophils, Basophils, Monocytes, and lymphocytes) This cell acts in the destruction of disease-causing microorganisms.
It acts in the removal of necrotic cell debris in the lung, such as bacteria, viruses, also destroying old cells in our body, cleaning the organism.
In some cases the cell does not necessarily need phagocytosis to feed itself, this can be called digestion. autophagic intracellular, cells digest their own material, old organelles, which can also be called cell suicide or apoptosis.
