there are 2 types of bone tissue within a long bone.
• Compact/Cortical bone – This is made up of rod like structures which are tightly packed together, making it dense and strong.
• Spongy/Cancellous bone – This is a honeycomb like structure (looks similar to the inside of a sponge) this makes it lightweight, yet strong. The honeycomb structure allows blood vessels to pass in and out of the bone to import and export nutrients and blood cells
