Each blood cell type
Is designed for a specific function.
Deficiency in that cell type will cause impairment in that function. Rbc deficiency (aka anemia
) reduces o2 carrying capacity, neutrophil deficiency raises risk for bacterial and fungal infections, b-cell def reduces antibody
production, t-cell def raises risk for most things because they have a master regulator role in the immune system. Plt def = bleeding.
