Human blood is created in the bone marrow, the soft, spongy material inside bones. It's responsible for producing about 95% of the body's blood cells. The bone marrow houses hematopoietic stem cells, which are the building blocks for all types of blood cells, including red blood cells, white blood cells, and platelets. These stem cells undergo a highly regulated process called hematopoiesis, transforming into the different blood components.
The bone marrow continuously produces blood cells, replacing old or damaged ones. This process is essential for maintaining a healthy blood supply and ensuring proper oxygen transport, immune defense, and blood clotting.
