| phagocytose | To perform phagocytosis, denoting the action of phagocytic cells. Synonym: phagocytise. Origin: L. Phagedaena, Gr Phago, To eat. (05 Mar 2000) |

| phagocytosis | <cell biology> Endocytosis of particulate material, such as microorganisms or cell fragments. The material is taken into the cell in membrane bound vesicles (phagosomes) that originate as pinched off invaginations of the plasma membrane. Phagosomes fuse with lysosomes, forming phagolysosomes in which the engulfed material is killed and digested. Origin: L. Phagedaena, Gr Phago, To eat. (18 Nov 1997) |
| phagocytosis view phagocytosis | The process by which a cell is engulfed and broken down by another for purposes of defense or sustenance.The uptake of extracullular materials by the formation of a pocket from the cellular membrane and its subsequent pinching off.Compare endocytosis and pinocytosis.

| phagodynamometer | A device for measuring the force required to chew various foods. Origin: L. Phagedaena, Gr Phago, To eat. (05 Mar 2000) |
| phagolysis | 1. Destruction of phagocytes, or leukocytes, occurring in the process of blood coagulation or as the result of the introduction of certain antagonistic foreign substances into the body. Synonym: phagolysis. 2. A spontaneous breaking down of the phagocytes, preliminary (according to Metchnikoff) to the liberation of cytase, or complement. Origin: phagocyte + G. Lysis, dissolution (05 Mar 2000) |
| phagolysosome | A body formed by union of a phagosome or ingested particle with a lysosome having hydrolytic enzymes. (05 Mar 2000) |
| phagolytic | Relating to phagocytolysis. Synonym: phagolytic. (05 Mar 2000) |
| phagomania | <psychiatry> Rarely used term for a morbid desire to eat. See: bulimia. Origin: L. Phagedaena, Gr Phago, To eat. (05 Mar 2000) |
| phagophobia | <psychiatry> Morbid fear of eating. Origin: phago-+ G. Phobos, fear (05 Mar 2000) |
| phagosome | <cell biology> A membrane-bound cytoplasmic vesicle that forms around a particle (bacterial or other) by invagination of phagocytised material. It forms within the phagocyte that engulfed it, then separates from the cell membrane, and fuses with and receives the contents of cytoplasmic granules (lysosomes), thus forming a phagolysosome, in which the hydrolytic enzymes of the lysosome digest the phagocytised material. Origin: L. Phagedaena, Gr Phago, To eat. Soma, body (05 Mar 2000) |
| phagotype | <microbiology> A subdivision of a species distinguished from other strains therein by sensitivity to a certain bacteriophage or set of bacteriophages. Origin: phago-+ G. Typos, type (05 Mar 2000) |
