Growth and Structures
Bones contain cells and tissue such as blood and nerves. Since your bones are alive, they from new cells and tissue as you grow but even after you have grown, bone tissue continues to form within your bones. Every time you do a sport or something, your bones absorbs the force of your weight. Your new bone tissue can also form after an accident.
Inside a bone, there is the "Bone Marrow." The bone marrow consists of two different types of marrows. One of the marrows contains red blood cells this is located in the ends of the femurs, skull, hip bone, and sternum which is your breast bone. The other marrow stores fat, which serves as an energy reserve.
Also in side the bone there is the ''Compact Bone." This bone is hard and dense but not solid. Just inside the compact bone is a layer of spongy bone. This structure of the spongy bone is light weight but very strong. There are small canals that run through the compact bone. These canals carries blood vessels and nerves from the bone's surface to the living cells that are within the bone.
