10 FACTS ABOUT THE: SKELETAL SYSTEM
Transcript of 10 FACTS ABOUT THE: SKELETAL SYSTEM
Around 70 percent of your bones are not living tissue, but hard minerals like calcium
If your body doesn't have enough calcium, it will take it from your bones making your bones weaker
Your knees and elbows are joints. The shoulder and hip are ball and socket joints
At the center of bones is a softer substance called marrow.
There are two types of bone marrow, yellow and red. Yellow bone marrow is mostly fat cells. Red marrow is important because this is where our body produces red and white blood cells
When we are born, all of our bones have red marrow. By the time we are adults about half of our bones have red marrow.
The spine is made up of 33 bones.
Although your bones stop growing when you are around 20, they do constantly rebuild new bone cells.
Very few man made substances can come close to the lightness and strength of bones
Your body can heal broken bones all on its own, a doctor will only help it along, and making sure that the bone heals straight and properly using a cast or sling
