The Role of Blood in the Body
The many roles of blood include delivering nutrients and oxygen to cells, transporting waste from cells, and maintaining homeostasis.
Red Blood Cells
Red blood cells, made from bone marrow stem cells, are crucial for the exchange of oxygen and carbon dioxide throughout the body.
White Blood Cells
White blood cells, also called leukocytes, play an important role in the body's immune response by identifying and targeting pathogens.
Platelets and Coagulation Factors
Platelets and coagulation factors are instrumental in plugging damaged blood vessel walls and stopping blood loss.
Plasma and Serum
Plasma is the liquid component of blood after all of the cells and platelets are removed; serum is plasma after coagulation factors have been removed.
