Although we may get cuts and bruises our bodies are actually quite amazing.

Phagocytosis definition anatomy. In higher animals phagocytosis is chiefly a defensive reaction against infection and invasion of the body by foreign substances antigens. Pinocytosis definition the transport of fluid into a cell by means of local infoldings by the cell membrane so that a tiny vesicle or sac forms around each droplet which is then taken into the interior of the cytoplasm. Phagocytosis the envelopment and destruction of bacteria or other foreign bodies by phagocytes.

The principal phagocytes include the neutrophils and monocytes types of white blood cells. Characteristic of amebas and some types. The ingestion of a smaller cell or cell fragment a microorganism or foreign particles by means of the local infolding of a cells membrane and the protrusion of its cytoplasm around the fold until the material has been surrounded and engulfed by closure of the membrane and formation of a vacuole.

The word phagocytosis comes from the greek phago meaning devouring and cyte meaning cell. Phagocytosis is the engulfing or ingestion of foreign substances in our bodies such as microbes bacteria debris and damaged or worn out tissue cells. A process of taking in fluid together with its contents into the cell by forming narrow channels through its membrane that pinch off into vesicles and fuse with lysosomes that hydrolyze or break down contents.

In some forms of animal life such as amoebas and sponges phagocytosis is a means of feeding. The process by which a cell engulfs particles such as bacteria other microorganisms aged red blood cells foreign matter etc.
