Study Notes
Blood Composition and Function
- Platelets' primary function is to form blood clots and stop bleeding.
- White Blood Cells (WBCs) function to protect the body against infection and disease.
Blood Cells
- Erythrocytes (red blood cells) main function is to carry oxygen from the lungs to the body's tissues.
- Hematocrit measures the percentage of red blood cells in the blood.
Blood Proteins
- Albumin's main function is to regulate blood pressure and transport substances in the blood.
- Globulins are divided into three types: alpha, beta, and gamma globulins.
Blood Cell Production
- Hemopoiesis occurs in the bone marrow, where blood cells are produced.
- Erythropoietin stimulates the production of red blood cells.
- Thrombopoietin stimulates the production of platelets.
Immune System
- B cells mature in the bone marrow and play a crucial role in the immune system.
- RhoGAM is a drug that prevents an immune response in Rh-negative mothers.
Anemia and Blood Disorders
- The most common form of anemia is iron deficiency anemia.
- Polycythemia is caused by an overproduction of red blood cells.
Blood Types and Compatibility
- In the ABO blood group system, antibodies play a crucial role in determining blood type.
- Blood type O negative is called the universal donor in emergencies because it can be transfused to anyone regardless of their blood type.
Reticulocytes and Leukocytes
- Reticulocytes are immature red blood cells that mature into erythrocytes.
- Leukocytes, also known as white blood cells, function to protect the body against infection and disease.
- Eosinophils intensify inflammation like mast cells.
Coagulation and Clotting
- Von Willebrand factor plays a crucial role in the blood clotting process.
- Thrombocytopenia is a condition characterized by low platelet levels.
- A thrombus is a blood clot that forms in a blood vessel.
- The extrinsic pathway of coagulation is quicker and caused by trauma.
