Skeletal+system

= Skeletal system =

There are many systems in the human body but there is only one that has bones: the skeletal system. Your bones are made up of living tissue cells, b lood vessels, and mineral deposits such as calcium phosphate. The skeletal system is really important to our body. It gives the body structure and helps protect your internal organs. The skeletal system is what helps your body move. The way bones work is very interesting and unique. They start out as cartilage and begin getting coated with calcium phosphate until they become hard bones. Babies have over 300 bones and as they get older, their bones fuse into 206 bones. Bones can help give your body amazing abilities. Bones are important to our body. If it wasn’t for them we wouldn’t have as much protection.

Bones are not organs but they protect organs such as the heart, lungs, liver, and brain. The skull protects our brain and the ribs protect our heart, lungs and liver. There are many things inside a bone that people don’t know, starting with calcified bone. It is one of the layers of a bone also known as compact bone. The next layer is called spongy bone which has living tissue. The darkest layer of bone is called the bone marrow deep inside your bones. There is a part of bone called the “cancellous.” It is a layer of bone made out of marrow, spongy bone, and calcified bone. Another part of your bones is called the periosteum, a thick membrane contains nerves and blood cells that nourish the bone. These are many layers of the bone that serve to protect organs.

Bones works with many other systems in the human body. The muscular system allows bones to move. The skeletal system works with the circulatory system because blood cells are produced in the bone. The bones also protect the heart. The skeletal system helps the respiratory system by protecting the lungs and the heart. The skeletal system also works with the excretory system because the bones protect the kidneys. The skeletal system also works with the nervous system (brain) as the skull protects it. The digestive system helps the bone grow by giving it calcium sugar and proteins. The skeletal system helps the reproductive system with the pelvis. The pelvish elps protect partofthe reproductive system and makes room for childbirth by flexing. These are all the other systems that the skeletal system works with.

There are many ways to keep your bones healthy and protected. Whenever you’reriding a bike always wear a helmet to prevent a fracture. Exercise to keep your bones healthy. Keep your bones healthy by drinking milk andeating diary. This will help prevent osteoporosis (mineral loss which causes the bones to get weaker as you get older.
