Phagocytes A type of white blood cell the "eats" dead cells, and other "debris" in the blood.
----------------------------- A phagocyte is a white blood cell that 'engulfs' not only dead cells and debris but also reacts against Pathogens (disease causing micro-organisms). There are different types of phagocytes e.g. Macrophages or Neutrophils.
The process where a Phagocyte 'disposes' of a pathogen is called phagocytosis, when a bacteria attaches to a phagocyte, using ligands, The phagocyte forms Pseudopods (cytoplasmic arms) that envelope the pathogen, the Psuedopodia then fuse, creating a membrane, enclosing the pathogen forming a phagosome, this moves deeper within the cell to then form with a lysosome forming a phagolysosome (not really imaginitive naming i know, but scientists aren't known for their imaginative naming ). the lysosome contains enzymes (you guessed it, lysozyme) the lysozyme destroys the bacterial cell walls allowing hydrolytic enzymes to digest the rest of the pathogen.

*** white blood cells that engulf and destroy pathogens***
white blood cells
Of your white blood cells, about a quarter are called lymphocytes. They release antibodies to destroy pathogens. Phagocytes are another type of white blood cell; they make up roughly 75% of the body's WBCs. Phagocytes ingest microbes, instead of killing them with antibodies.
No
Three types of white blood cells can act as phagocytes: neutrophils, eosinophils and monocytes. They can migrate outside of the bloodstream.
* Neutrophil * Eosinophil * Basophil * Lymphocyte * Monocyte * Macrophages * Phagocytes
Monocytes are the largest unicuclear white blood cells.
The two categories are granulocytes and agranulocytes. Granulocytes have visible cytoplasmic granules. Examples of granulocytes include neutrophils, eosinophils, and basophils. Agranulocytes have no visible cytoplasmic granules. Eamples of agranulocytes include lymphocytes and monocytes.
No eosinophils were observed
Eosinophils increases in amount when there are parasitic infection. These WBCs(eosinophils) attacks parasite through chemical means.
This means that no eosinophils were observed in the blood sample taken and observed. This is not necessarily pathologic as eosinophils are the second rarest white blood cell type in the blood stream.
neutrophils, basophils, eosinophils.
Yes, phagocytes can engulf germs
what is the process by which phagocytes destroy a pathoger
Eosinophils are a type of white blood cell, not a disease. Its not contageous.
No, eosinophils defend against parasitic worms
