Study Notes
Definition of Hematology
- The branch of medicine focused on the study of blood, blood-forming organs, and blood diseases.
Components of Blood
-
Red Blood Cells (RBCs)
- Contain hemoglobin for oxygen transport.
- Lifespan of around 120 days.
-
White Blood Cells (WBCs)
- Involved in immune response.
- Types include neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
-
Platelets (Thrombocytes)
- Key role in blood clotting.
- Lifespan of about 7-10 days.
-
Plasma
- Liquid component of blood, comprising water, electrolytes, proteins, hormones, and waste products.
Functions of Blood
- Transport: Oxygen, nutrients, hormones, and waste products.
- Regulation: Body temperature, pH levels, and fluid balance.
- Protection: Immune defense against pathogens and clotting mechanisms.
Common Hematologic Disorders
-
Anemia
- Decreased RBC count or hemoglobin.
- Types include iron-deficiency, pernicious, and hemolytic anemia.
-
Leukemia
- Malignant disease of blood-forming tissues characterized by overproduction of abnormal WBCs.
- Types include Acute Lymphoblastic Leukemia (ALL) and Chronic Myeloid Leukemia (CML).
-
Lymphoma
- Group of blood cancers affecting lymphatic system.
- Includes Hodgkin’s and Non-Hodgkin's lymphoma.
-
Thrombocytopenia
- Low platelet count, leading to increased bleeding risk.
- Can be caused by bone marrow disorders, medications, or certain infections.
Diagnostic Procedures in Hematology
-
Complete Blood Count (CBC)
- Provides information on RBCs, WBCs, hemoglobin, hematocrit, and platelets.
-
Peripheral Blood Smear
- Examination of blood under a microscope to assess the shape and number of cells.
-
Bone Marrow Biopsy
- Examines the bone marrow for diseases and disorders.
-
Coagulation Tests
- Assess blood clotting function (e.g., PT, aPTT).
Treatment Options
-
Medications
- E.g., iron supplements for anemia, chemotherapy for leukemia.
-
Blood Transfusion
- Replacement of blood components.
-
Bone Marrow Transplant
- Treats severe hematologic diseases by replacing diseased marrow.
-
Gene Therapy
- Emerging treatment for genetic disorders affecting blood cells.
Conclusion
- Hematology encompasses the essential study of blood and its disorders.
- Understanding hematological functions and diseases is critical for diagnosis, treatment, and management of various health issues.
