    • Gwen NytesBONES
    • What Are They For? Bones are used formovement, support, and protectingthe organs in your body. They storeminerals and produce red and white blood cells.
    • System Interactions Circulatory System-the bone marrow produces red blood cells, white blood cells, and platelets, which are part of the circulatory system. Muscular System-this system is made of muscles that are attached to your bones by tendons to help you move, and to give you more structure. Your skeletal muscles are the voluntary muscles attached to bones.Immune System-Bones produce white blood cells, which are the main part of the immune system. They are used to fight off things that don’t belong in the body.
    • Parts Of The System
    • JointsJoints are the part of the system inwhich bones meet each other. They are essential for movement. Thebones in joints are usually connectedby ligaments. There are around 230 moveable and partially moveable joints in your body, as well as some immoveable joints.
    • Bone MarrowBone marrow is found in every hollow bone. There are two types of marrow-red and yellow. The red bone marrow produces platelets, red blood cells, and white blood cells. Some white blood cells are formed in yellow bone marrow, along with fat, cartilage, and bone cells.
    • Bones Bones are made of two types of tissues; compact bone tissue andspongy bone tissue. The four kinds of bones are long bones, short bones, flat bones, and irregular bones. Bones are used to protect organs in the body, and to give structure to the body.
    • How Are They Made?When you are a baby, some of your bones weren’t all bone, but also part cartilage. With the help of calcium, that cartilage turns into bone as you grow.
    • How Did Bones Evolve? Early soft bodied animals had cartilage. Just like how bones are formed out of cartilage in ourbodies, the same thing happened to them. The cartilage eventuallyturned into bone, and now they have bones.
