Immune System
Leukocytes
Macrophages: large phagocytes that are found all over the body, they consume antigens and give the information to other cells to save
T and B cells: produce in the bone marrow, the T cells move to the thymus and mature there while the B cells remain in the bone marrow to mature. T cells help recognize and trigger an immune response. B cells produce and release antibodies once the antigen is recognized
Monocytes: large phagocytic white blood cells that can differentiate into macrophages or dendritic cells. they are important to the process of adaptive immunity
-
Dendritic cells: are found in tissues in contact with the environment and affect the adaptive immunity process for microbes
Eosinophil: phagocytic cell that defends from multicellular infections by surrounding the antigens and releasing damaging enzyems
Antibodies
When a foreign species enters the body, the immune system might produce these as a response
-
-
Histamines (stored in mast cells) are an inflammatory trigger that makes the blood vessels near the damaged tissues to become more permeable
-
Types of Barriers
-
To seal a wound, platelets release a clotting factor that makes fibrin fibers to form across the wound and capture blood cells to form a clot
Vaccines
They make people immune to a disease without ever being exposed to it. They contain antigens that don't cause symptoms; which, once they're injected into the body, cause a primary response from the immune system. This makes new memory cells that remember the antigen so that the next time this disease is found in the body, there is a secondary response that is much quicker.
Methods of Transmission
Droplets in the air, skin to skin contact, bodily fluids, animal vectors, blood contact, ingestion
