Why do we have a skeletal system? Simpily because if we didnt we would be a big blob of skin and gross stuff...
There are many bones in our head that I never knew about...
We need bone structure over our brain because without it all of our knowledge would be gone.... This is just simply said!!
Bones protect all of our insides in other words.
Inside bones contain the main blood supply... We have bone marrow. Inside our bones is a matrix which consists of osteocytes in lacunae...To have healthy bones we need plenty of calcium!!! Think about it how would we eat meat without teeth... Blend it? I dont think so yuck!!
Bones are the structure to keep our organs safe and keep us mobile! Without bones just imagine how life would be :(
These are just some of the bones in our body!!!
Here is a video that I got more explination from hope it helps you also!! enjoy!!
