What are two functions of bone marrow cavities?
Two functions of bone marrow cavities:
1. Hemopoiesis or Production of Blood Cells: Bone marrow cavities are the primary site for the production of various blood cells. This process, known as hematopoiesis, occurs in the red bone marrow, which is found within the cavities of most bones. Inside the bone marrow cavities, specialized cells called hematopoietic stem cells differentiate and develop into different types of blood cells, including red blood cells, white blood cells, and platelets.
2. Storage and Release of Minerals: Bone marrow cavities also serve as storage sites for minerals, primarily calcium and phosphorus. These minerals are incorporated into the bone's mineralized matrix, giving bones their strength and rigidity. When the body requires these minerals, such as during periods of calcium demand for bone growth or muscle contraction, the bone marrow cavities can release the minerals into the bloodstream for use by various tissues.
