Study Notes
Lymphatic and Immune System Overview
- Lymphopoiesis: The formation of lymph, crucial for immune function.
- Interstitial Fluid: Found in the spaces between cells; transforms into lymph upon entering lymph capillaries.
- Immune System Components: Platelets are NOT part of the immune system.
Lymph Node and Tissue Concentration
- Lymph Node Concentration: Concentrations are primarily in areas like lymph nodes and spleen; bone marrow is not considered a concentration area.
- Tcells Types: Includes helper and suppressor cells, vital for immune response.
Immune Responses and Allergies
- Atopy: A hypersensitivity or allergic condition involving exaggerated immune responses.
- Immunoglobulins: Key examples include IgA, IgG, and IgE, which play various roles in immune defense.
Lymphatic Organs and Functions
- Tonsils: Comprised of oropharyngeal lymph tissue, acting as the first line of immune defense.
- Thymus: The primary producer of T-cells, critical for adaptive immunity.
- Adenoids: Located in the nasopharynx, similar function to tonsils.
- Spleen: Filters erythrocytes and activates lymphocytes; essential for blood-related immune responses.
- Bone Marrow: Responsible for producing lymphocytes, monocytes, and all other blood cells, pivotal for overall immunity.
Immune Cell Types and Functions
- Cytotoxic T-Cell Lymphocytes: Responsible for directly killing infected cells and tumors.
- Antiviral Proteins: Interferons and interleukins are produced by T-cells to combat viral infections.
- Lymphocytosis: Refers to a slight increase in lymphocyte numbers, often indicative of an immune response.
Terminology Related to Health Conditions
- Toxicity: Pertaining to poison, important in understanding harmful effects on health.
- HIV: The virus responsible for AIDS, impacting the immune system significantly.
- Hodgkin Lymphoma: A malignant tumor affecting lymph nodes, impacting lymphatic health.
Infection Types Associated with AIDS
- Herpes Simplex: A viral infection causing blisters on the skin, commonly around the lips, nose, or genitals.
- Kaposi Sarcoma: Cancer arising from capillary lining cells, characterized by bluish-red skin nodules.
- Pneumocystis Jiroveci Pneumonia: Major lung infection treated with Bactrim, noted for symptoms like fever and cough.
- Toxoplasmosis: A protozoal infection linked to AIDS, which can lead to pneumonitis, hepatitis, and encephalitis.
- Cryptococcosis: Fungal infection associated with AIDS that can affect the brain, meninges, lungs, and skin.
