Study Notes
Functions of Blood
- Transportation of O2, CO2, nutrients (glucose, calcium), hormones, and waste products.
- Regulation of body temperature, pH, and overall homeostasis.
- Protection through hemostasis (clotting) and immunity (antibodies).
Components of Blood
- Blood comprises formed elements (cells and fragments) and plasma (liquid matrix).
- Formed elements include leukocytes (white blood cells), erythrocytes (red blood cells), and thrombocytes (platelets).
- Plasma consists of water, proteins, and other solutes; key for transporting substances.
Hematology Overview
- Study of blood components in health and disease.
- Formed elements arise from stem cells in bone marrow.
- Examines issues related to RBCs, WBCs, platelets, blood vessels, and proteins involved in bleeding and clotting.
Hematopoiesis
- Hemopoiesis encompasses erythropoiesis (red cells), leukopoiesis (white cells), and thrombopoiesis (platelets).
- Hematopoietic locations include organs and tissues, with red bone marrow producing blood cells.
- Distinction between red marrow (active) and yellow marrow (fatty).
Blood Cell Development
- Multipotent stem cells can differentiate into various cell types, leading to progenitor/committed stem cells, blasts, and mature cells.
- Two main cell lines: myeloid (produces RBCs, platelets, granulocytes) and lymphoid (produces lymphocytes).
Salaries in Hematology/Oncology
- Median income for hematologists/oncologists is $481,250.
- Salary range varies from 328,540to328,540 to 328,540to810,850 based on experience and location.
Clinical Uses of Blood Components
- Plasma is used for patients recovering from blood loss during surgeries or severe injuries.
- Serum is employed in diagnostics, research, and immunotherapy (e.g., vaccination).
- Antivenoms produced from animal serum counteract specific venoms through neutralization.
Blood Composition and Volume
- Blood volume averages 5-6 liters in males and 4-5 liters in females.
- Blood consists primarily of plasma (approximately 55%) and formed elements (approximately 45%).
Distinction Between Plasma and Serum
- Plasma is the liquid component of blood; serum is plasma without clotting factors.
- Understanding the difference is crucial in clinical settings for blood treatment and analysis.
Key Plasma Constituents
- Water (92%): Serves as a solvent and heat absorber.
- Proteins (7%): Produced mostly by the liver; regulate colloid osmotic pressure, pH, and transport hormones and fatty acids.
Major Plasma Proteins
- Albumins: Smallest plasma proteins with crucial roles in maintaining osmotic pressure and transporting various molecules.
