Q

BQ: What is the passive movement of blood cells across endothelial wall?

A

Diapedesis
- (after mag line up ng wbc sa periphery or pavementing, magmmove yung wbc across endothelial wall or endothelium which is the wall of the blood vessel because antigen is outside the blood vessel or at the surface)

Humoral immunity

A
  1. Bcells bind to antigen’s epitope

  3. Antigen will be digested and production of MHC 2
  4. CD4 will read MHC 2 and will result to
    - CD4 activation
