The Skeletal System

The Structure & Function(s)
What is the function of the skeletal system? The job of the skeletal system is to provide support - the spine is what allows us to remain upright. Other jobs that the skeletal system is movement and calcium storage. They store calcium, which allows our bones to be strong and hard to break.

What are the names and functions of the major organs in the skeletal system? 
The names & functions of the major organs in the skeletal system are...


  • Bones: such as the cranium, or also known as our skull, that protects our brain. The human body has 206 bones which is the main framework that provides support and protection to our more vulnerable organs.
  • Ligaments & joints: ligaments are collagen tissue that connect one bone to the other. These attachments are formed into joints, allowing the bone(s) to move in a certain range of area & direction. The term "double-jointed" comes from certain people who can stretch these joints past a "normal level".
  • Tendons: like ligaments, tendons connect muscles to the bones. They are also more flexible, allowing a greater range of movement. This contraction pulls to the end of the bone, and that is what makes the bone move when running or walking or doing some other form of movement. 
  • Cartilage: the material that makes up our nose and ears (a shark's fins) is a soft & flexible connective tissue, which protects the bones against friction forces (without the cartilage protecting the bones, the friction would damage the bones easily). 

The structure and function of bones: The size of the bones in the skeletal system come in different sizes. Their structures are quite different, which is why I'll be writing a paragraph about a few of them. 
   First off, we have the cranium (the skull), which protects our brain from a lot of damage. The way the cranium is designed is to shape around the brain to, as I mentioned before, protect it, almost like a mold, but not quite.
   Second, we have the clavicle (or more commonly known as the collarbone), which is a doubly curved bone that keeps the shoulders separate from our rib cage & allows the arm to move freely.
   And the third and final bone out of the 206 bones in the skeletal system is the ribcage. The rib cage's structure is built to curve around our lungs and prevent them from any damage, like the cranium. The rib cage's shape allows it to protect the heart as well.

Interactions with other systems: 
The skeletal system has a connection with the muscular system - literally. The muscles connect to the bones and the muscles are what move the bones (a muscle is series of connected tissue that contract and expand to allow movement) along. The bones itself are calcified (calcium is in milk which strengthens your bones) and made up of cartilage (cartilage is the material that makes up your nose & ears) to tolerate smoother action. 
   The calcified bones also work with the circulatory system (the circulatory system consists of the heart, blood vessels, blood, lymph, and the lymphatic glands & vessels. This system works on circulating blood and lymph throughout the body, hence the name circulatory system). The blood marrow inside of the bones helps produce the blood cells (blood cells are what give your blood the red color - your actual blood (without the blood cells) is yellow), both red and white blood cells that remove waste, fight off diseases, and provide oxygen.

Analogy:

The analogy: I chose the Great Wall of China and the rib cage for my analogy. Why? Because the Great Wall of China (when the Silk Road was still used) protected travelers from bandits when traveling. The rib cage does the same - protects the heart and lungs from injuries or shocks that might damage them.

REDESIGN: How Can I Make This System Better?
How would you make this system better?: I would make this system better by making the bones stronger - it would much harder to bruise/break them (I had a classmate who ran into a metal pole accidentally and was diagnosed with bruised ribs). I would also make this system better by making sure the bone marrow only produces a certain amount of blood cells at a time - sometimes the bone marrow produces too much, causing an autoimmune condition, which is where your body attacks your own cells.
