List the components of blood as red blood cells, white blood cells, platelets and plasma
Answer
The components of blood include:
- Red Blood Cells (RBCs):
- Function: Responsible for transporting oxygen from the lungs to the body tissues and returning carbon dioxide from the tissues back to the lungs.
- White Blood Cells (WBCs):
- Function: Part of the immune system, helping to fight infections and diseases. They include various types such as lymphocytes (which produce antibodies) and phagocytes (which engulf pathogens).
- Platelets:
- Function: Play a crucial role in blood clotting by aggregating at sites of injury and converting soluble fibrinogen into insoluble fibrin, preventing blood loss and entry of pathogens.
- Plasma:
- Function: The liquid portion of blood that transports blood cells, nutrients (like glucose and amino acids), hormones, ions, carbon dioxide, urea, vitamins, and plasma proteins throughout the body.
These components work together to maintain vital functions in the body, including oxygen transport, immune defense, clotting, and nutrient distribution.
