| Osteoblasts (bone cells) mature into WHAT and sit within the hard bone matrix and maintain bone. | Osteocytes |
| Name the 2 types of bones: | Compact and spongy |

| In compact bone, blood supplies the tissues with WHAT and WHAT? | oxygen and nutrients |
| Spongy bone is also called WHAT? | Cancellous |
| This type of bone has no osteon/haversian systems. | Spongy or cancellous bone |
| Spongy/cancellous bone tissue is arranged in plates called WHAT? | Trabecule |
| The trabecule plates in spongy/cancellous bone is separated by holes similar to WHAT? | Swiss cheese |
| The holes in spongy/cancellous bone decrease bone weight and contains what? | Red bone marrow |
| The bone marrow in spongy/cancellous bone supplies the bone with WHAT and also produces these cells for use throughout the body. | blood cells |
| This type of bone is found in short/flat/irregular bones and at the ends of long bones. | Spongy/cancellous bone |
