Immune System
Major Functions of the Lymphatic and Immune System
Lymphatic System
Protect the body from illness-causing invaders,
Maintain body fluid levels, absorb digestive tract fats,
and removing cellular waste.
Immune System
Fight disease causing germs and remove them from
the body, to recognize and neutralize harmful substances
from the environment, and to fight disease-causing changes in the body.
Innate(natural)immune defenses and Adaptive(acquired)immune defenses
Innate (natural) Immunity
Physical Barriers (skin, body hair, etc.)
Defense Mechanisms (Sweat, tears, etc.)
General immune response
Adaptive (acquired) Immunity
Only found in vertebrae, the adaptive immunity
response is specific, attack non-self pathogens.
Humoral response and cellular response
Humoral Response
B-cells produce antibodies against
antigens in blood and lymph, memory
cells, etc. These cells create memories
so if the infection/virus comes back the
cells will know how to fight it.
Cellular Response
Binding chemical signals to receptors
within the cell changing the behavior
like whole cell movement, etc.
Anatomy of the Lymphatic System
The bone marrow, Spleen, Thymus gland,
Lymph nodes, and Tonsils
The heart, lungs, intestines, liver, and skin
also contain some lymphatic tissue
Antigens and Antibodies
Antigens
A foreign substance inducing
immune response in the body,
Antibodies
A blood protein produced in
response to a specific antigen
Cells involved in the immune system
Lymphocytes
T-cells, B-cells, and NK cells, neutrophils,
macrophages, White Blood
cells, cytokines, antibodies, and complement proteins.
Immune System Disorders
Type 1 Diabetes: Attacks the pancreas cells
Rheumatoid arthritis: Causes swelling and deformities
Lupus: Attacks body tissues (lungs, kidneys, and skin)
