Study Notes
Blood Components and Functions
- Gamma globulins: Class of plasma proteins that function as antibodies, essential for immune response.
- Clotting proteins: Serum is blood plasma without clotting proteins, crucial for hemostasis.
- Erythrocytes: Red blood cells are pivotal for blood viscosity, impacting circulation and oxygen transport.
- Ferritin: A complex in the liver that stores excess iron, vital for preventing iron deficiency.
Blood Disorders and Conditions
- Hemolytic anemia: Can be caused by mushroom poisoning, highlighting toxic impacts on red blood cells.
- Pernicious anemia: Results from a lack of intrinsic factor, necessary for vitamin B12 absorption.
- Hemophilia: A hereditary condition caused by the lack of clotting factor VIII, leading to increased bleeding risk.
- Sickle cell disease: A genetic mutation alters one amino acid in hemoglobin, causing misshaped red blood cells and related health issues.
- Polycythemia: Refers to an excessive rise in red blood cell count, which can lead to complications like increased blood viscosity.
Hemostasis and Coagulation
- Thromboplastin: Activates the extrinsic pathway of coagulation in response to blood vessel damage.
- Factor X: The clotting factor common to both intrinsic and extrinsic pathways, playing a key role in the coagulation cascade.
- Hemostasis: Overall process to stop bleeding, involving vascular spasm, platelet plug formation, and coagulation.
Blood Types and Compatibility
- Agglutination: Not part of homeostasis; a reaction that can occur in incompatible blood transfusions.
- Agglutinogens: RBC antigens that determine blood type and transfusion compatibility, crucial for safe transfusions.
- Type O+ parent: A type O+ baby cannot have an AB- mother, reflecting genetic inheritance patterns.
Blood Production and Measurement
- Hemopoiesis: The process of producing all formed elements in the blood, including red blood cells, white blood cells, and platelets.
- Hematocrit: Measurement of the percentage of whole blood volume made up of red blood cells, indicating red blood cell concentration.
- Erythropoietin: A hormone released by the kidneys that stimulates the production of red blood cells, crucial in response to low oxygen levels.
Nutritional Aspects
- Vitamin B12: Critical for proper red blood cell formation, its absorption requires intrinsic factor.
