Primary lymphoid tissue
•Bone marrow and thymus
Secondary lymphoid tissue
•Lymph nodes, spleen, tonsils, Peyer’s patches
lymph fluid
the clear liquid akin to plasma. It carries wastes, filters debris from the system.
•Tissue fluid
SURROUNDING TISSUES
Thoracic Duct:
•drains lymph from both legs, abdominal & pelvic cavities, the left half of the thorax, head, neck and left arm.
Right Lymphatic Duct:
•drains lymph from the right half of the thorax, head, neck and right arm
Non specific immunity
first and second line of defence
Alimentary tract
Foods and liquids
Genitourinary tract
organs of the reproductivesystemand theurinary system.
First line of defence
Physical eg. skin and chemical barriers eg. tears
Second line of defence
Phagocytosis and inflammation
Third line of defence
B and T lymphocytes
Pathogen
disease causing agent
Antigen
specific surface marker on pathogens that can be detected by white blood cells
