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.

What else can I help you with?
What are the characteristic features of granular phagocytes?
Granular phagocytes, primarily neutrophils and eosinophils, are characterized by the presence of granules in their cytoplasm, which contain enzymes and antimicrobial substances. Neutrophils are key players in the innate immune response, actively engulfing pathogens and releasing their granules to kill bacteria. Eosinophils are involved in combating parasitic infections and modulating allergic responses. Both types of granular phagocytes are essential for inflammation and the body's defense against infections.
What are the 5 primary white blood cells?
The five primary white blood cells are neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each plays a role in the immune system, such as fighting infections (neutrophils), producing antibodies (lymphocytes), and controlling allergic reactions (eosinophils).
What are white blood cells with one large nucleus called?
Monocytes are the largest unicuclear white blood cells.
What are two main categories of leukocytes?
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.
What does a 0 L absolute eosinophils mean?
No eosinophils were observed
What are eosinophils responsible for?
Eosinophils increases in amount when there are parasitic infection. These WBCs(eosinophils) attacks parasite through chemical means.
What does absolute eosinophils 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.
Can phagocytes engulf bacteria?
Yes, phagocytes can engulf germs
What is the process by which phagocytes destroy a pathogens?
what is the process by which phagocytes destroy a pathoger
Is eosinophils contagious?
Eosinophils are a type of white blood cell, not a disease. Its not contageous.
How do phagocytes get rid of micro-organisms?
phagocytes engulf and then digest the microorganisms to get rid of them.
Are eosinophils predominate at the sites of chronic infections?
No, eosinophils defend against parasitic worms
