Study Notes
Medical Terminology (DPY 121) - Lecture 6 - Part 1
- Topic: Blood, Lymphatic System & Immunology
-
Learning Objectives:
- Define word parts used in medical terms for blood, the lymphatic system, and immunology.
- Break down and define common medical terms for symptoms, diseases, disorders, procedures, treatments, and devices associated with blood, the lymphatic system, and immunology.
- Build medical terms from word parts associated with blood, the lymphatic system, and immunology.
- Pronounce and spell common medical terms associated with blood, the lymphatic system, and immunology.
Blood
- Composition: Plasma and blood cells
- Function: Transports oxygen and nutrients to tissues, returns waste products to the kidney, and is part of the immune system.
Word Roots
- hem/o, hemat/o: Blood
- erythr/o: Red
- leuk/o: White
- thromb/o: Clot
- cyt/o: Cell
- lipid: Fat
- immun/o: Immunity
- lymph/o: Lymph
- aden/o: Lymph node or gland
- tonsill/o: Tonsil
- path/o: Disease
- tox/o: Poison
Suffixes
- -emia: Condition in the blood.
Blood Components/Cells
- thrombocytes (platelets): Essential for blood clotting
- erythrocytes (RBCs): Red blood cells that carry oxygen.
- leukocytes (WBCs): White blood cells involved in the immune response.
- plasma: Liquid part of blood, containing nutrients, waste products, and hormones.
Formed Elements of Blood
- Red Blood Cells (Erythrocytes): Shown as round, red structures, carrying oxygen.
- Platelets (Thrombocytes): Shown as small, irregular, dark colored structures, involved in clotting.
- White Blood Cells (Leukocytes): Shown as various (monocyte, lymphocyte, eosinophil, basophil, neutrophil), round structures involved in the immune response.
Lipids: Fats
- Lipoprotein profile: Measures cholesterol, HDL, LDL, and triglycerides in the blood.
Lymphatic System
- Function: Removes waste products from intercellular fluid, destroys harmful substances (e.g., pathogens and cancer cells) in lymph nodes, and returns filtered lymph to the bloodstream.
- Components: Lymph, lymph nodes, lymphatic vessels. Includes organs thymus, liver, spleen.
Word Roots (Lymphatic System)
- angi, vascul, vas: Vessel, blood vessel
- lymphaden: Lymph node/gland
Signs and Symptoms
- Hemorrhage: Bleeding (capillary, venous, arterial)
Blood Disorders
- Leukopenia: Deficiency of white blood cells
- Polycythemia: Condition with high red blood cell count
- Thrombocytosis: Abnormal increase in platelets
- Thrombocytopenia: Deficiency of platelets
- Anemia: Deficiency of red blood cells
- Hematoma: Mass of blood outside blood vessels (a bruise if visible)
- Leukemia: Cancer characterized by abnormal increase in white blood cells
- Septicemia: Infection in the blood
- Thrombosis: Condition of a clot in a blood vessel.
- Embolism: Blockage of blood vessel by a tissue or clot or air bubble
- Hyperlipidemia: High level of fat (cholesterol) in blood.
- Lymphadenopathy: Disease of lymph nodes.
- Lymphedema: Swelling due to abnormal accumulation of lymph fluid
- Immunodeficiency: Defective immune response due to low number of lymphocytes
Treatments and Procedures –
- Vital Signs: Temperature, pulse, respiration, blood pressure
- Phlebotomy: Drawing blood
- Complete Blood Count (CBC): Laboratory test to check blood health status.
