An awful lot!
Bones contain bone marrow, that spongy substance that fills the bones, are essential for the production of blood cells. Actually, the red bone marrow is for red blood cells, but - if needed -, the yellow (fatty) bone marrow could convert into the red blood cell making type. Otherwise, yellow bone marrow can produce some of the white blood cells.
From the age of 6 month, foetus' (unborn baby) bone marrow could make blood cells (before that, its yolk sac, then its spleen and liver do the task). When the child is born, marrow in the majority of its bones can produce blood cells. In adults, marrow only in specific bones, like pelvis, vertebrae, ribs, skull, sternum and a few others, are producing.
In normal conditions, responding to signals/regulations/interventions from receptors, hormones, cytokines, paracrine agents, and others, the bone marrow matches the need for new blood cells. Hematopoietic stem cells start the process, blood cells differentiate and mature into the needed type, then leave the bone marrow and join the peripheral blood stream. (except T lymphocytes, which mature in the thyroid).

The periosteum, a thin membrane surrounding bones, is responsible for supplying blood to the outer layer of bones.
