Phagocytes

• Macrophages & Dendritic Cells

• scavengers and sentries
• produce cytokines
• live for weeks to months; replace lysosomes (granules)

• Neutrophils

• rapid response team (Calvary); first on scene
• short half life, 1-2 days in tissue
• can not replace lysosomes (granules)
• once expended -> die -> pus
