Skeletal system

Skeletal system

Skeletal system function: 2 main things that the skeletal system does is to protect you and to supports you. The skeletal system protects you by covering your organs to protect them and it supports you like support beams. The skeletal system also you move and have a shape.

Organs: The skeletal system doesn't have any of those squishy red organs but it does have a lot of different types of bones. One of them is the spine and the spine is made up of 26 bones of total and they're called vertebrae. The spine helps you to be flexible like bend and twist but it also keeps you upright. Next is the Ribs and the ribs keep other organs like the heart, lungs, and your liver. The rib has 12 bones in total but some people have less and some people are born with more bones but normally it will be 12. After is your skull and the skull protects the brain which is the most important of all. There's also something called a suture which connects your bones together.  Then there's your hands and you hands are what give you the availability to hold, touch, and type. It also has bones that help it function such as the scapula, humerus, radius, and ulna. These bones make up and connect the arm. Then if you combine your hands, wrists, and every one of your fingers there are 54 bones in total. After is the legs that help you run, and walk. The legs also have other bones to help it such as the femur, patella, tibia, and fibula. Then if you combine your feet and your ankle you have 52 bones in total. The next organ/bone is the joints and the joints is where 2 bones meet. There are different joints in your body such as the parieto-temporal, the hinge joint, and the ball and socket. Then there's something called ligaments which keeps your bones together like rubber bands.

The spine's structure and function: The spines structure is like a long beam with a bunch of bones and one sharp one on the end of it. If the spine didn't exist then the whole skeletal system would fall apart and it also protects things called spinal cords. The spinal cords transport messages from the brain to different parts of the body so you can do things. It also lets you be flexible like turning around to look at something. It also helps you to bend down and reach for something if it's on the floor or the side.

Relationship with other systems: The muscular system works with the skeletal system because the skeletal system protects the muscular system. The bones in the skeletal system are made of cartilage which helps the skeletal system by making its process smoother. The skeletal system also works with the circulatory system which helps the bones in the skeletal system create red and white blood cells. It creates this because there's marrow in your bones which creates those cells.

Analogy explanation: The skeletal system is like table legs because it helps support your body (the table) by keeping you upright. Then the table legs (the skeletal system) supports the table (your body).

REDESIGN: One way I could redesign the skeletal system is to make it so your bones aren't sore the day after you do something that drains all your energy. The bones in your body are strong but you still get sore after 1 day of maybe football or basketball practice.
