-Can elicit an immune response within the host.
Antigen

eosinophils
neutrophils
monocytes

Three major types of lymphocytes
T-cells
B-Cells
Natural Killer Cells

Natural Killer Cells
travel where the invaders are detected and considered phagocytic cell
Neutrophils
are responsible for fighting parasites, viruses, and allergies
Eosinophils
play a role in allergic reactions
Basophils
are responsible for destroying pieces of invaders
Monocytes
these carry lymph which contains the white blood cells
Lymph vessels
are bean-shaped clusters cells capable of trapping antigens
Lymph nodes
————– carry lymph to the nodes while ————- carry them away from the nodes
Afferent lymph vessels ,
efferent lymph vessels
are parts of the body found in the respiratory tract
tonsils

type of tonsil that produce antibodies
Lingual tonsils
is capable of destroying and segregating malfunctioning cells.
Spleen
two parts of spleen
Red pulp
White pulp
is where T cells mature
Thymus
is responsible for the production of different types of white blood cells.
Bone Marrow
