IMMUNOLOGICAL BARRIERS
-
Tertiary barriers
Once the infection is developed,we need the action of the third barrier , produces several substances that attack invading agents directly.The most important are antibodies.
The don't attack pathogen microorganisms directly.Produce molecules named antibodies, join them to facilitate their destruction.
-
Lymphocytes B
They are capable of searching, recognizing and destroying cells. Destroy infected and cancer cells
-
Proteins produced by lymphocytes that adhere to pathogen microorganisms, can be destroyed directly (second barrier), correspond to the group of leukocytes and are divided into two types
The integrity of an organism is constantly threatened by a series of events such as wound or the presence of strange agents.The immune system is in charge of provoking the immune response; this immune response generates specific immunity, know as acquired immunity.
Secondary barriers
When primary barriers are defeated, inflammation occurs, which helps to direct certain defense mechanism to the point where the injury or wound is located
The secondary barriers are white cells or leukocytes,which are specialized in defending the organism . There are different types of leukocytes: neutrophils , monocytes , basophils and eosinophils .
