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.

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.
