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 |
