Natural (innate) immunity and Acquired (specific) immunity
What is the main characteristic of natural (innate) immunity?
Non-specific
What are the primary components of natural (innate) immunity?
Soluble factors, barriers, membranes, secretions, immune cells (phagocytes, inflammatory cells, complement)
What are the primary lymphoid organs involved in the immune system?
Bone marrow and thymus gland
Which cells participate in the acquired (specific) immune response?
T and B lymphocytes, APC (Antigen Presenting Cells)
What is the function of the thymus gland in the immune system?
The thymus gland aids in the maturation of T cells and produces the hormone thymosin.
How do B cells differ from T cells in their immune response?
B cells develop antibodies instead of whole cell reactivity against antigens and have greater diversity, forming billions of antibodies with different reactivities.
What molecules can act as antigens (Ags) in the immune system?
Proteins, polysaccharides, lipoproteins, or glycolipids
