The action of phagocytes

Macrophages can also be called

antigen presenting cells

Neutrophils are found in

blood

Phagocytes are produced by

bone marrow and stem cells

Macrophages are made in

bone marrow and stem cells, they are called monocytes until they reach organs

A large proportion of pus is made from

dead neutrophils

The phagocyte digests the microbe in 6 stages, they are

detection, ingestion, phagosome (phagocytic vesicle) forms, fusion with lysosome containing digestive enzymes, digestion and discharge

After digesting bacteria neutrophils

die

A pathogen is defined as a

disease causing organism

Some microbes can live in phagocytes for years by being

dormant

Some microbes can evade the immune system by

entering phagocytes and prevent fusion of a vesicle and so attachment to a lysosome, it then can rapidly reproduce inside the phagocyte (e.g. chlamydia or tuberculosis)

Phagocytes are described as

human cells that ingest microbes by phagocytosis

Macrophages role in the body is to

initiate an immune response by presenting the antigens of the bacteria they have digested to the lymphocytes

In size macrophages compared to neutrophils are

larger

Macrophages live span is

long

Microflora is the name given to

microorganisms associated with the body but don't cause disease, they reduce the growth of harmful bacteria

60% of white blood cells are made up of

neutrophils

The 3 phagocytes are

neutrophils, monocytes and macropages

Macrophages are found in

organs

There are 2 types of white blood cell

phagocyte and lymphocytes

Some microbes can kill phagocytes by

producing toxins

The 2 types of lymphocytes are

B and T

All phagocytes are a type of

white blood cell

During infection what is released is large amount of

white blood cells
