LYMPHATIC SYSTEM BASICS
This system is made of fluid, vessels, tissues, and organs that support immunity, regulate fluid balance, and transport dietary fats.
What is the lymphatic system?
These structures trap and destroy invaders that enter through the mouth and nose.
What are the tonsils?
These proteins created by B-cells bind to pathogens.
What are antibodies?
Immunity gained from vaccines is known as this type of immunity.
What is active immunity?
This autoimmune disorder affects the spine and causes stiffness.
What is ankylosing spondylitis?
This fluid is called interstitial fluid in the tissues but becomes lymph once inside the lymphatic system.
What are interstitial fluid and lymph?
This organ houses hematopoietic stem cells that develop into blood cells.
What is red bone marrow?
These two cells work together: one activates B-cells, the other kills infected cells.
What are helper T-cells and killer T-cells?
This type of immunity is achieved when the body is exposed to a pathogen and forms antibodies on its own.
What is active immunity?
This condition is NOT an immune system disorder because it is caused by outside pathogens.
What is infectious disease?
These vessels transport lymph in a one-way network back toward the heart.
What are lymphatic vessels?
Located in the lowest portion of the small intestine, these nodules monitor gut pathogens.
What are Peyer’s patches?
These cells patrol tissues, trapping and killing invading pathogens.
What are neutrophils?
These specialized B-cells remember previously encountered antigens.
What are memory cells?
This disorder occurs when a missing piece of chromosome 22 affects immune function.
What is DiGeorge syndrome?
These veins return filtered lymph from the lymphatic trunks back into the bloodstream.
What are the subclavian veins?
These anchor lymphatic capillaries to surrounding tissue cells.
What are fibrous filaments?
True or False
Lymph nodes are the primary site of adaptive immune activation and antigen presentation.
True
Vaccines work because they trigger B-cells to produce these proteins.
What are antibodies?
This life-threatening reaction occurs when the immune system is overly active in response to harmless substances.
What is an allergic reaction?
This layer of the skin contains no lymphatic tissue.
What is the epidermis?
This duct drains lymph from the entire body except the upper right quarter.
What is the thoracic duct?
This term refers to any substance that triggers an immune response.
What is an antigen?
This type of immunity results from the body receiving antibodies from an external source.
What is passive immunity?
This autoimmune disease causes rashes, fatigue, fever, joint pain, and shortness of breath.
What is lupus?
