Phagocytosis



Phagocytosis: important defense mechanism

Introduction (what it is)

In phagocytosis the cell surrounds and sends solid particles into it. A very classic example of this process occurs in our immune system, when macrophages (defense cells) phagocyte pathogenic microorganisms (viruses, bacteria, etc.).

How it happens (summary)

Once the antigen is inside, the defense cell will self-destruct (a process known as autolysis). These defense cells have the important function of eliminating aggressors to our body.

Phagocytosis occurs in two phases, the first is the process of ingestion, in which the cell will spend a lot of energy until it carries the particle inside. The second is intracellular digestion of the ingested particle, here some microorganisms may be destroyed. Autolysis will not always occur.

Importance of Phagocytosis and Function

Simply put, we can understand that phagocytosis is a very important mechanism of our organism, which protects it against the invasion of disease-causing agents.
