(Immune Vessels & Cells)
These tiny vessels are found between tissue cells and blood capillaries, and are very permeable
Lymphatic Capillaries
This lymphatic organ functions primarily during childhood, and disappears by adulthood
The Thymus
The names of two types of mechanisms that defend the body against microbes which together make up the Immune System
Innate & Adaptive Systems
These are hypersensitivities to specific substances, from pollen and pets to chemicals and foods, that trigger strong immune responses
Allergies
This fluid travels through lymphatic vessels and is returned to the blood
Lymph
The compression and relaxation of these move lymph throughout the body
Skeletal Muscles
These small masses of tissue in the throat trap and remove bacteria and foreign particles
The Tonsils
The two main parts of the first line of defense in the innate body defenses
The surface membrane barriers of the skin's physical barrier and acid mantle.
This is a rare, severe, and extremely strong response of the immune system to a substance from the 100 category in this topic
Anaphylactic Shock
This response is nonspecific and triggered whenever body tissues are injured
In the lymph nodes, these cells engulf and destroy bacteria, viruses, and other foreign substances
Macrophages
These collections of tissue look like tonsils but are located in the wall of the small intestine, and aid in capturing and destroying harmful bacteria
Peyer's Patches
These innate defense cells are aggressive lymphocytes that roam the body and lyse cancer cells and virus-infected body cells
Natural Killer (NK) Cells
The name for a group of diseases where the body attacks its own tissues, thinking that they are foreign
Autoimmune Diseases
These cells confront pathogens that make it past the body's mechanical barrier in the innate defense system
Phagocytes
The three clusters of lymph nodes are located in the inguinal, cervical, and this region
Axillary
This small organ is located on the left side of the body, just below the diaphragm, and cleans the blood of bacteria and old blood cells
The Spleen
This term refers to antibody-mediated immunity provided by our immune proteins present in the body's fluids
Humoral Immunity
These conditions occur when the body is unable to produce immune cells or the function of those cells is impaired
Immunodeficiencies
This medical treatment, required throughout childhood and strongly recommended each year, contributes to our body's adaptive immune systems by training our immune system to recognize various pathogens
Vaccinations
In a lymph node, this is where macrophages are located
The Medulla
All lymphoid organs have a lot of this type of connective tissue as well as lymphocytes
Reticular connective tissue
These substances are capable of provoking an immune response when they are recognized as nonself
Antigens
This chronic immune system disease is caused by the human immunodeficiency virus, was a much feared epidemic of the 1980s, and is now treatable
AIDS
