Blood and Lymphatic System

  • Hematopoiesis/Hemopoiesis: Development and maturation of blood cells.
  • Blood: Connective tissue composed of plasma.
  • Erythrocytes (Red Blood Cells): Live ~120 days, contain hemoglobin, crucial for oxygen transport.
  • Erythropoiesis: Production of red blood cells.
  • Leukocytes (White Blood Cells): Protect against bacteria and foreign substances.
  • Diapedesis: White blood cells migrating through capillary walls into tissues.
  • Leukopoiesis: Production of white blood cells.
  • Granulocytes: Most abundant leukocytes, contain granules in their cytoplasm.
    • 3 Types: Neutrophils, Eosinophils, Basophils.
    • Neutrophils: Most numerous, phagocytic (engulf and destroy bacteria), appear at injury/infection sites.
    • Eosinophils: Protect against toxins and increase in allergies/parasite infections.
    • Basophils: Release histamine (increases blood flow) and heparin (prevents clotting).
  • Agranulocytes: Arise from bone marrow stem cells.
    • 2 Types: Monocytes and Lymphocytes.
    • Monocytes: Mildly phagocytic in blood vessels; transform into macrophages at inflammation sites.

  • Blood Capillaries: Exchange fluids with tissues.
  • Lymph Capillaries: Collect fluid (lymph) from tissues and return it to blood.
  • Lymph Nodes: Filter lymph; sites for immune cell activity (macrophages, T and B cells).
  • Spleen: Filter; removes damaged cells, bacteria.
  • Thymus Gland: Develops T cells of the immune system.

  • Medical Terminology Prefixes: List of prefixes (aden/o, agglutin/o, blast/o, chrom/o, erythr/o, granul/o, hem/o...).
  • Medical Terminology Suffixes: List of suffixes (penia, phil, -phylaxis,...).
  • Hematology: Study of blood and blood-forming tissues.
  • Hematologist: Physician specializing in hematology.
  • Allergy and Immunology: Study of the immune system.
  • Allergist/Immunologist: Physician specializing in allergies and immunology.

  • Allergies: Abnormal immune response.
  • Allergy Symptoms: Hives, eczema, allergic rhinitis, asthma, anaphylactic shock.
  • Allergy Treatments: Desensitization.
  • Autoimmune Diseases: Body attacks self-tissue.
  • Leukemia: Cancer of blood-forming cells.
  • Leukemia Types: Chronic, Acute.
  • Leukemia Treatment: Chemotherapy, radiation, biological therapy, bone marrow transplant.
  • AIDS (Acquired Immunodeficiency Syndrome): HIV infection weakens immune system.
  • Coagulation Disorders: Problems with blood clotting.
    • DIC (Disseminated Intravascular Coagulation): Widespread clotting in small vessels.
    • Hemophilia: Hereditary clotting factor deficiency.
    • Thrombocytopenia: Low platelet count.
  • Graft Rejection: Immune system attacks transplanted tissue.
  • Graft-Versus-Host Disease: Transplant cells attack recipient's tissues.
  • Hemoglobinopathy: Disorders associated with abnormal hemoglobin.
  • Infectious Mononucleosis: Epstein-Barr virus infection.
  • Kaposi Sarcoma: Cancer related to human herpes virus.
  • Lymphedema: Lymph accumulation in tissues.
  • Lymphoma: Cancer of immune system cells (lymphocytes).
