monocyte, Eisonophiles, phagocytes
monocyte
Most common WBC
-Phagocytic (ingest harmful stuff)
-Can leave body and enter infected tissue
Neutrophil
what is Susceptibility

-Least common WBC
-Produce histamine , important Inflamm response
Basophil
what is the First line of Defense
-Intact skin
-Mucous membranes & secretions
-Normal Microbiota
define Valence?
The number of determinant sites on an antigen or
antibody
Where is lysozyme found?
perspiration, tears, saliva, nasal secretions, tissue fluids, and urine
Where do b cells develop?
in the bone marrow
list the chemical factor of the first line defense ?
