Lymphatic system
Question | Answer |
---|---|
2 functions of the lymphatic system | Filtration & immunity |
Purpose of lymphatic vessels | Filters intracellular fluid ( tissues) |
Pathway of the lymphatic system | Lymph capillaries ~> lymph vessels ~> Rt lymphatic duct ~> thoracic duct ~> empties into LFT subclavian vein |
The lymphatic system flows in one direction away from _____ and towards ______ ______ | Tissue & Thoracic Cavity |
Lymph Nodes AKA | Lymph Glands |
Lymph Nodes produce | Phagocytes ~> Macrophages Antibodies |
Four major concentrations of lymph nodes | Cervical, Mediastinal, Axillary, Inginual |
What is immunity | Body's ability to protect itself from disease (pathogen) |
What is resistance | To build immunity |
What is lack of resistance | To be Susceptible |
Two types of immunity | Natural Immunity & Acquired immunity |
What is natural immunity | What you were born with |
Three types of acquired immunity | Passive, active, artificial |
What is passive immunity | Immunity given to patient ( breast-feeding) |
What is Active immunity | Produce immune response naturally ( cold ) |
What is artificial immunity | To produce anti-bodies ( vaccine ) |
Includes T cells plus B cells | Immune reaction |
Cell mediated immunity ~> Direct action of cells ( phagocyte) | T cells |
Humoral immunity ~> production of antibodies | B cells |
Antibodies that react against its own tissues is an | Auto immune disorder |
Lupus, Erthematosus, Sclerderma and RA | Collagen diseases |
Lidiopathic, thromboc, topenic purura & acquired hemolytic anemia | Hemolytic diseases |
Abnormal condition characterized by excessive reaction to a particular stimulus | Hypersensitivity |
Occurs when an immune system fails to protect itself against foreign materials. Antibodies forms certain body cells causing a hyper sensitive or allergic reaction | Hypersensitivity |
Occurs at the site where treatment or medication was given | Local reaction |
Evidence by generalized body systems such as a runny, nose, itchy eyes, hives and rashes | Systematic reaction |
Severe sometimes fatal hyper sensitive or allergic reaction | Anaphylaxis |
Antibody reaction can stimulate a massive secretion of histamine | Antigen |
