I was talking to my science teacher about the body specifically the red bone marrow.
She said that blood is created in the red bone marrow. Does that mean that if you were to cut a fresh bone open it would bleed?

Yes, bones too bleed if they get damaged (break or bruise). This is because bones are highly vascularised organs and breaking of bones will indeed rupture the blood vessels causing bleeding. Main artery which supplies blood to bone is nutrient artery , others are epiphyseal, metaphyseal and periosteal arteries. Skeletal system receives about 15.6% of cardiac output. Since bones contain very low percentage of water ( about 31% ) comapred to others like skin(64%),brain and heart (73%) and lungs ( 83%). So the saying "as dry as bone " stills holds well.
