Natural/Innate Immunity
Acquired/Adaptive Immunity
Natural/Innate Immunity parts
Anatomical Barriers

Mechanical Factors
Skin
Mucus
ANATOMICAL BARRIERS
Chemical Factors
Fatty acids
Surfactants
ANATOMICAL BARRIERS
Biological factors
Normal flora of the skin and GIT
play an important role in inflammation, characterized by edema and phagocytic cells.
Humoral barriers to infection
Humoral barriers to infection
These factors are found in the ________ or at the _______________
serum
site of infection
Enumerate the non-specific plasma proteins
Complement system
Coagulation system
Lactoferrin and transferrin
Interferons
Betalysin
Properdin
Once activated complement can lead to increased vascular permeability, recruitment of phagocytic cells, and lysis and opsonization of bacteria.
Complement system
COMPLEMENT SYSTEM
Once activated complement can lead to increased:
Vascular permeability
Recruitment of phagocytic cells
lysis and opsonization of bacteria
Some products of the coagulation system can contribute to the non-specific defenses because of their ability to increase vascular permeability and act as chemotactic agents for phagocytic cells.
Coagulation system
are a group of cytokines that are secreted by different cells of the immune system that function for cellular growth modulation, differentiation, and activation during inflammatory and immune responses.
Interleukins
These cells are the main line of defense in the non-specific immune system.
Cellular barriers to infection
Enumerate the kinds of Cellular barriers to infection
Neutrophils
Macrophages
Mast cells
Dendritic cells
Natural killer (NK) and lymphokine-activated killer (LAK) cells
Eosinophils, Basophils
Monocytes
Third line of defense
Acquired/Adaptive Immunity
Affords protection against re-exposure to the same pathogen
Acquired/Adaptive Immunity
cells responsible for the specific immune response
Lymphocytes
Types of Acquired/Adaptive Immunity
