Study Notes
Overview of Hematology
- Hematology is the branch of medicine focusing on blood, blood-forming organs, and blood disorders.
- It includes studying red blood cells, white blood cells, platelets, and the processes of their formation, function, and related disorders.
- Hematopoiesis is the formation of blood cells, primarily in bone marrow.
Red Blood Cells (Erythrocytes)
- Erythrocytes carry oxygen throughout the body.
- Hemoglobin, the oxygen-binding protein, is present in erythrocytes.
- Normal erythrocyte shape is essential for efficient oxygen transport.
- Abnormal shapes can indicate conditions like iron deficiency or thalassemia.
- Erythrocytes transport oxygen to tissues and carbon dioxide back to the lungs.
White Blood Cells (Leukocytes)
- Leukocytes are part of the immune system, fighting infections.
- Different types of leukocytes, each with specific roles in immunity, exist.
- Granulocytes (neutrophils, eosinophils, basophils) combat infections.
- Lymphocytes (B cells and T cells) are crucial for adaptive immunity.
- Monocytes/macrophages have phagocytic (engulfing pathogens) abilities.
- White blood cell counts can indicate infections.
Platelets (Thrombocytes)
- Platelets are vital for blood clotting.
- They release factors initiating the clotting cascade.
- Adequate platelet counts maintain normal hemostasis (stopping bleeding).
- Low platelet counts increase bleeding risk.
Hematopoiesis
- Hematopoiesis is the continuous blood cell development from pluripotent hematopoietic stem cells.
- This process mainly takes place in bone marrow.
- Blood cells mature through stages, undergoing changes.
- Hormones and growth factors regulate hematopoiesis.
Common Hematological Disorders
- Anemia is a condition of reduced red blood cell count.
- Various types of anemia exist, each having distinct causes.
- Leukemia is a blood cancer, arising from blood-forming cells.
- Leukemia types differ by cell type and progression.
- Lymphoma is a lymphatic system cancer, including Hodgkin's and Non-Hodgkin's.
- Hemophilia is a bleeding disorder, caused by clotting factor deficiencies.
- Thrombocytopenia is low platelet count.
- Disseminated intravascular coagulation is widespread abnormal blood clotting.
- Polycythemia vera involves increased red blood cell production.
Diagnostic Methods in Hematology
- Peripheral blood smear analysis is a microscopic blood examination.
- It assesses blood cell morphology and quantity.
- Complete blood count (CBC) measures blood components.
- CBC includes red blood cell count, hemoglobin, hematocrit, white blood cell count, and platelet count.
- Bone marrow examination assesses blood cell production.
Clinical Significance
- Hematological conditions cause various symptoms, depending on the condition's severity.
- Common symptoms include fatigue, weakness, pallor, bleeding, and infections.
- Diagnosis combines clinical assessment, lab tests, and potentially imaging.
- Treatments range from supportive care to therapies like chemotherapy or blood transfusions.
