Why is bone marrow primarily red in infants?
Infants grow relatively fast and need quite a lot of red blood cells, which are only produced in red bone marrow. As the infants grow older, much of the red bone marrow is gradually replaced by yellow bone marrow containing a special kind of fat that gives it its yellowish color. If the body needs more red blood cells than the remaining red marrow is capable of producing, some of the yellow marrow changes to red marrow.
Type of bone tissue that contains marrow?
There are 2 types of bone tissue: Spongy or cancellous bone (head of most large bones, ribs, shoulder blade) and Compact (in the diaphysis or middle part of large bones). Compact bone forms the extremely hard exterior while spongy bone (also called cancellous bone) fills the hollow interior. Within the inside of the long bones is bone marrow.
What kind of bones make blood?
Bone marrow. Bone marrow is where blood cells are created. Only long bones (with the "hole" in the center) have bone marrow in them. So leg bones and arm bones make blood cells, but rib bones or skull bones do not. So those short, solid, irregular-shaped bones do not create blood cells.
How do compact and spongy bones differ?
Spongy Bone has more surface area, but it is weaker and not as dense as compact bone. Compact Bone is the tough outer layer of bone while spongy bone is the porous bone where the red and yellow marrow is. Spongy is softer bone, with holes in it. It is found inside the bone. It is lighter than compact bone. Compact bone is generally on the outer edges of bone. it is composed of multiple osteon units that are bunched closely together like stacked logs and, thus, is good at bearing weight in the long direction. Spongy bone is generally on the inside of compact bone. Individual osteon-like struts (called trabeculae) branch in many directions and interconnect. Thus, there are spaces created where red marrow exists. This kind of bone is good at handling stress from multiple directions and is lighter weight. Spongy bone can appear yellow because it has some fat in it, and it is possible to see small holes in spongy bone. Compact bone is usually white. Also, spongy bone is not long (like the wrist) most irregular and flat bones are formed from spongy bone tissue. Compact bone is usually long (like a femur). Compact bone tissue is hard with few open spaces & provides protection and support.Spongy bone tissue is porous with many open spaces
