Red marrow
* contains the stem cells that produce most types of blood cells.
* is bone marrow
  - involved in blood cell formation
  - the main site of blood cell formation throughout adult life
* produces blood cells
  - red and white blood cells and platelets

Yellow marrow
* consists primarily of cells that store fat.
* contain a large amount of fat.
  - fatty tissue
  - found inside the hollow middle section of the long bones
  - made mainly of fat cells
+ Bone marrow, Marrow types: Bones
  * There are two types of bone marrow. Red blood cells, platelets, and most white blood cells are created by red marrow. Yellow marrow is made mainly of fat cells. Both types of bone marrow contain many blood vessels and capillaries.

### bone tissue:

Compact bone

  - physical characteristics
* Some compact bones have canals.
* are bone tissue.

  - follow characteristics
* is added to create bone tissue that is similar to the original, unbroken bone
  - composed of tubular units called Haversian systems
  - dense and homogeneous and forms the walls of bone
  - dense, hard, and forms the protective exterior portion of all bones
  - denser and has fewer spaces than spongy bone
  - smooth and dense
  - the hard material under the periosteum
  - very strong and dense, having no spaces within it other than the Haversian canals
* lies over spongy bone and composes most of the bone tissue of the diaphysis
  - makes up most of the diaphysis
* makes up the dense outer layer of bone
  - shaft of a long bone

### bone tissue:

Spongy bone
* Most spongy bones contain marrow
* Some spongy bones are covered by layers
  - form inner layers
* appears porous, has less bone matrix and more space than compact bone.
* consists of bars, spicules or trabeculae, which forms a lattice meshwork
  - trabeculae with numerous red marrow-filled spaces
* fills the expanded ends of long bones.
* forms the inner layer.
* has many spaces between bony struts.
* is deep to compact bone
  - found in the ends of long bones such as the femur
* is found inside many long bones
  - the epiphysis, and is less compact than compact bone
  - strong yet decreases the weight of the skeleton
* makes up the inner portion and is less dense, softer, and weaker.
* occurs at the ends of bones and has bony bars and plates separated by irregular spaces
  - long bones and is less dense than compact bone
  - in most bones

Bonfire
* Some bonfires also have an effigy of a witch on a broomstick on top of the fire.
