Study Notes
Introduction to Blood
- Blood is the fluid that circulates throughout the body, delivering oxygen and nutrients while removing waste products from tissues.
- Blood is composed of plasma (55%) and formed elements (45%).
- Plasma is the liquid part of blood and contains water, proteins, and hormones.
- Formed elements include red blood cells, white blood cells, and platelets.
Blood Cells
- Erythrocytes (Red Blood Cells) carry oxygen and carbon dioxide.
- Leukocytes (White Blood Cells) play a role in immunity and defending against infections.
- Thrombocytes (Platelets) are involved in blood clotting (hemostasis).
Immunity
- Immunity is the body's defense against harmful microorganisms and foreign substances.
- Innate Immunity refers to non-specific, inborn defenses like skin and mucus.
-
Adaptive Immunity is an acquired defense that is specific to certain pathogens.
- Adaptive immunity relies on T Cells and B Cells.
- T Cells provide cell-mediated immunity, directly attacking foreign invaders.
- B Cells are responsible for humoral immunity, producing antibodies.
- Adaptive immunity relies on T Cells and B Cells.
Medical Terminology Related to Blood
- Hem/o, Hemat/o: These roots refer to blood. (Example: hemopathy)
- Erythr/o: Refers to red. (Example: erythropoiesis)
- Thromb/o: Refers to clot. (Example: thrombosis)
- Leuk/o: Refers to white. (Example: leukocytosis)
Medical Terminology Related to Blood & Immunity
- Hematocrit: The proportion of red blood cells in the blood.
- Hemostasis: The process of stopping bleeding including blood clot formation.
- Immun/o: Refers to immunity or the immune system.
Medical Terminology Related to Immunity
- Immunization: The process of inducing immunity.
- Immunoglobulin (Ig): Antibody proteins that offer protection against infections.
- Antigen: A substance that triggers an immune response.
- Antibody (Immunoglobulin): A protein produced by B cells that helps neutralize pathogens like bacteria and viruses.
- Neutropenia: A decrease in the number of neutrophils, a type of white blood cell, making the body more vulnerable to infections.
- Eosinophil: A type of white blood cell involved in allergic reactions and fighting parasitic infections.
- Lymphocyte: A type of white blood cell involved in immune response.
Disorders Related to Blood
- Anemia: A deficiency of red blood cells or hemoglobin.
- Leukemia: Cancer of the blood and bone marrow that involves the overproduction of white blood cells.
Disorders Related to Immunity
- Autoimmune Diseases: The immune system attacks the body's own cells.
- Immunodeficiency Disorders: A weakened immune system, as seen in (human immunodeficiency virus) HIV.
Medical Terminology: Prefixes, Suffixes & Roots
- -phylaxis: Refers to protection or prevention. (Example: Prophylaxis)
- Anaphylaxis: A severe, potentially life-threatening allergic reaction.
- Lymph/o: Refers to lymph or the lymphatic system, part of the immune system. (Example: Lymphocyte)
- Lymphadenopathy: Disease affecting the lymph nodes.
- -globulin: Refers to proteins involved in the immune response. (Example: Immunoglobulin)
- Gamma globulin: A substance containing antibodies given for passive immunity.
- Auto: Prefix meaning "self". (Example: Autoimmune)
- Autoantibodies: Antibodies produced by the immune system that attack the body’s own cells.
- -cytosis: Refers to an abnormal increase in the number of cells. (Example: Leukocytosis)
- Hypersensitivity: An exaggerated immune response to a foreign substance.
- Hypersensitivity reaction: Immune responses that result in damage to tissues, ranging from mild to severe (e.g., anaphylaxis).
Clinical Case: Iron Deficiency Anemia
- Patient: Jane Smith
- Age: 45 years
- Gender: Female (F)
- Occupation: Office Worker
- Presenting Complaint: Fatigue, shortness of breath on exertion, frequent headaches, increased dizziness, especially when standing up quickly.
- Investigations:
- Complete Blood Count (CBC):
- Hemoglobin: 9.0 g/dL (normal: 12-15 g/dL)
- Hematocrit: 28% (normal: 36-46%)
- Ferritin: 8 ng/mL (normal: 20-200 ng/mL)
- Iron levels: Low
- Complete Blood Count (CBC):
- Diagnosis: Iron Deficiency Anemia secondary to chronic blood loss from menorrhagia (heavy menstrual bleeding).
- Treatment: Ferrous sulfate 325 mg PO daily for 3 months.
