Study Notes
Blood Composition and Functions
- Plasma is the liquid matrix of blood, primarily composed of water and dissolved substances like proteins, ions, and organic molecules.
- Major plasma proteins include:
- Albumins: Contribute to osmotic pressure and transport substances.
- Globulins: Involved in clotting, enzymes, and transporting substances.
- Fibrinogens: Essential for blood clotting.
- Transferrin: Transports iron.
Cellular Elements of Blood
- Red blood cells (RBCs): Transport oxygen and carbon dioxide.
- White blood cells (WBCs): Crucial for immune defense.
- Platelets: Cell fragments essential for blood clotting.
Hematopoiesis
- Hematopoiesis is the production of blood cells, occurring in the bone marrow.
- Subtypes include:
- Erythropoiesis (RBC production).
- Leukopoiesis (WBC production).
- Thrombopoiesis (platelet production).
- Key cytokines involved in hematopoiesis include erythropoietin (EPO), thrombopoietin (TPO), colony-stimulating factors (CSFs), and interleukins.
Platelets
- Platelets are involved in stopping blood loss, immunity, and inflammation.
- They form a primary plug at the site of wound.
- Their structure and function are essential during coagulation and fibrinolysis.
Hemostasis, Coagulation, and Fibrinolysis
- Hemostasis is the process of stopping bleeding.
- Coagulation is the process of forming a blood clot involving various steps, including a cascade of chemical reactions.
- Fibrinolysis is the enzymatic breakdown of the clot to restore normal blood flow.
- Thrombin converts fibrinogen into fibrin
- A blood clot is formed (reinforced by platelets)
- Fibrin is dissolved by plasmin.
- The above steps involve factors like platelets, plasminogen, tissue plasminogen activator (tPA) and fibrin.
