Study Notes
Functions of Blood
- Transports oxygen (O2) from the lungs and nutrients from the digestive tract to cells.
- Carries carbon dioxide (CO2) and metabolic wastes from cells to the lungs and kidneys for elimination.
- Distributes hormones from endocrine glands to target organs.
- Maintains homeostasis by regulating body temperature and extracellular fluid (ECF) pH.
- Absorbs and distributes heat to maintain appropriate body temperature.
- Utilizes buffer systems to maintain normal pH in body tissues.
- Ensures adequate fluid volume within the circulatory system to support circulation.
Immune Function
- Protects against infections through the action of white blood cells (WBCs) and antibodies.
- Synthesizes and utilizes antibodies to identify and neutralize pathogens.
- Activates WBCs to defend the body against foreign invaders effectively.
Hemostasis
- Prevents blood loss through clotting mechanisms.
- Activates plasma proteins and platelets in response to vessel injury.
- Initiates clot formation to seal broken blood vessels and prevent excessive bleeding.
Blood Composition
- Blood consists of cellular (red blood cells, white blood cells, platelets) and non-cellular components (plasma).
- Key blood cell types include erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes (platelets).
Erythropoiesis, Leucopoiesis, and Thrombopoiesis
- Erythropoiesis: Formation and maturation of red blood cells, regulated by erythropoietin hormone.
- Leucopoiesis: Production of white blood cells to support immune functions.
- Thrombopoiesis: Development of platelets crucial for blood clotting.
RBC Formation
- Sites for RBC formation vary with developmental age, occurring in various locations such as the yolk sac, liver, spleen, and bone marrow.
RBC Differentiation and Regulation
- Different stages of RBC differentiation include proerythroblasts, basophilic erythroblasts, and reticulocytes, each with unique features.
- Erythropoietin is secreted in response to hypoxia (low oxygen levels) and stimulates RBC production.
Clinical Conditions
- High levels of erythropoietin in the blood may be associated with certain clinical conditions, requiring further investigation.
