Study Notes
Key Terms and Definitions
-
Macrophage: A large phagocyte found in tissues that plays a critical role in the immune response by engulfing and digesting cellular debris and pathogens.
-
Lymph: A clear fluid that circulates through lymph vessels and lymph nodes, carrying immune cells and waste products.
-
Immunoglobulins: Also known as antibodies, these are proteins secreted by B-cell lymphocytes that help identify and neutralize foreign objects like bacteria and viruses.
-
Allergy: An abnormal immune response characterized by hypersensitivity to an antigen, leading to various symptoms ranging from mild to severe.
-
Inguinal Nodes: Lymph nodes located in the groin area; they filter lymph fluid and play a role in immune function.
-
Anaphylaxis: A severe and potentially life-threatening allergic reaction that triggers exaggerated hypersensitivity, often requiring immediate medical intervention.
-
Hodgkin Disease: A type of malignant tumor affecting lymphatic tissues, primarily found in the spleen and lymph nodes, which can lead to significant complications.
-
Axillary Nodes: Lymph nodes located under the arms (armpits), involved in filtering lymph and playing a role in the immune response.
-
Lymphocytopenia: A condition marked by a deficiency of lymphocytes, which can compromise the immune system and increase vulnerability to infections.
-
Splenectomy: A surgical procedure that involves the removal of the spleen, often done to treat or prevent illness related to spleen dysfunction.
-
Thymus Gland: An organ located in the chest responsible for the production of T cells, which are crucial for adaptive immune response.
-
Interstitial Fluid: Fluid found in the spaces between cells; it provides the environment necessary for nutrient and waste exchange at the cellular level.
-
Lymphedema: A condition characterized by the accumulation of lymphatic fluid in body tissues, often resulting in swelling, typically in the arms or legs.
-
Interleukins: A group of cytokines that play a vital role in immune system signaling; they stimulate the growth and activation of T cells.
-
Adenoids: Masses of lymphatic tissue located in the nasopharynx that help trap pathogens entering through the nose and throat.
-
Vaccination: The administration of a vaccine consisting of altered antigens to provoke an immune response, creating immunity against specific diseases.
-
Tonsillitis: Inflammation of the tonsils, often caused by infection, resulting in sore throat, difficulty swallowing, and swollen lymph nodes.
-
Lymphopoiesis: The process by which lymphocytes are formed from precursor cells, essential for maintaining a healthy immune system.
