Defensins
Give this one a try later!
Produced by granulocytes
Punch holes in bacteria membranes and cell walls
Forms of humoral immune response
Give this one a try later!
Primary and secondary
,Antigen presenting cell
Give this one a try later!
Present non-self antigen
Macrophages travel to lymph nodes to activate Helper T cells and
therefore are a type of antigen presenting cell
Interstitial fluid accumulation
Give this one a try later!
If interstitial fluid accumulation exceeds it's movement into lymphatic
capillaries, edema occurs
Ex: Menstral bloating
Misc. Chemical Barriers
Give this one a try later!
Not complement proteins
Ex: HCl acid and pepsin in stomach, salt on skin, antibacterial in tears
Characteristics of lymphatic capillaries
, Give this one a try later!
Similar anatomy as blood capillaries (simple squamous)
Closed ends
Same distribution as blood capillaries
Nonspecific defense
Give this one a try later!
Defense mechanism same regardless of type of pathogen
Ex: phagocytosis, fever, inflammation
Antibodies produced by primary immune response lasts how long?
Give this one a try later!
Antibodies last several months/ years
T cells (thymus derived)
