Study Notes
Blood Types
- AB+ is known as the "universal recipient" as it can accept blood from all types without risk of reaction.
- Type O- is referred to as the "universal donor" because it can be transfused to any blood type without causing complications.
Rh Factor
- Rh factor is an inherited protein found on the surface of red blood cells that can affect blood compatibility during transfusions and pregnancies.
Bleeding and Clotting Mechanisms
- Hemostasis is the process that stops bleeding while allowing normal blood circulation.
- Platelets are key blood components that assist in forming clots to stop bleeding when an injury occurs. They migrate to injury sites and form a plug.
Blood Cells and Hematopoiesis
- Red blood cells, or erythrocytes, contain hemoglobin and are responsible for transporting oxygen throughout the body.
- Hematopoiesis refers to the process of blood cell production occurring mainly in the bone marrow.
- White blood cells can be produced in various organs including the bone marrow, lymph nodes, and spleen, highlighting their role in the immune system.
Blood Compatibility
- Successful blood transfusions require compatibility between donor blood and recipient blood to prevent adverse reactions.
- Antigens are the markers or special traits on red blood cells that define blood types and can trigger immune responses if mismatched.
White Blood Cell Functions
- One function of white blood cells is to combat infections; they do not dissolve after healing, contrary to some misconceptions.
Special Blood Cell Properties
- Red blood cells have the ability to change shape to fit through various sizes of blood vessels, ensuring efficient circulation throughout the body.
