Bones in the skeletal system

The human skeleton has 206 bones. There are two layers to the bone. The exterior layer is called the compact bone because it is very dense and compact. The interior layer is called the spongy bone because it is less compact and has a more open lattice structure. In the spongy layer is where red marrow is found. Some of the bones of the human body include: the skull, ulna, radius, tibia, fibula, femur, phalanges, humerus, ulna, clavicle, etc.

The Importance of the Skeletal System

The skeletal system is all the bones and tissues such as; tendons, ligaments, and cartilage that connect them. The skeletal system is a very important structure for the human body. The skeletal system is strong but light. It’s main job is to provide support for our body. Without the skeletal system we would just be big blob of skin and guts on the floor.  Another important job of the skeletal system is to protect our internal organs. An example of this is the skull and how it protects our brain. The skeletal system also provides movement to the human body. They do this by providing the structure for muscles. Tendons are what muscles use to attach themselves to the bone.

How To Keep Bones Healthy

Bones require good amounts of exercise to stay strong and healthy. Walking and other activities like walking are a great way to keep your bones as strong as possible. Another great way to keep your bones strong is by drinking your milk, and by eating other dairy products that contain a lot of calcium. Calcium is important for bones because it helps them stay strong and hardened.
