The greater surface area in comparison with cortical bone makes cancellous bone suitable for metabolic ontains red bone marrow where haematopoiesis, the production of blood cells, occurs.
The greater surface area in comparison with cortical bone makes cancellous bone suitable for metabolic activity e.g. exchange of calcium ions. Cancellous bone is highly vascular and frequently contains red bone marrow where haematopoiesis, the production of blood cells, occurs.
