 * __Producing Body Heat-__ When skeletal muscles shorten and expand, body heat is given off.
 * __The Makeup of Organs and Vessels__- The shortening of smooth long, muslce within the walls of organs inside.

__Skeletal System: __
 * __﻿Movement- __Skeletal muscles attach to bones by tendons, that are very muscular amount of connective tissue.
 * __Protection- __<span style="color: #ff0000; font-family: 'Lucida Console',Monaco,monospace;">The bone is a hard structure that potects the organs that it surrounds.
 * __<span style="color: #ff0000; font-family: 'Lucida Console',Monaco,monospace;">Support- __<span style="color: #ff0000; font-family: 'Lucida Console',Monaco,monospace;">A strong bone that is well suited for supporting the weight of the body and the important tissue of the body.
 * __<span style="color: #ff0000; font-family: 'Lucida Console',Monaco,monospace;">Blood Cell Protection- __<span style="color: #ff0000; font-family: 'Lucida Console',Monaco,monospace;">Bones that include sections filled with bone marrow that helps blood cells be made.
 * __<span style="color: #ff0000; font-family: 'Lucida Console',Monaco,monospace;">Storage- __<span style="color: #ff0000; font-family: 'Lucida Console',Monaco,monospace;">The minerals in the blood are taken into parts of the bone and stored in there for later use.

By having more nucleouses making a lot proteins makes your muscles bigger.

<span style="color: #008080; font-family: 'Lucida Console',Monaco,monospace;">Skeletal Muscle- It is attached to bones skeletal muscle tissue can be made to contact or relax voluntarily.

<span style="color: #0000ff; font-family: 'Lucida Console',Monaco,monospace;">**4.** <span style="color: #800080; font-family: 'Lucida Console',Monaco,monospace;">Tedons and ligaments are tough structures used to connect bones together. They are found in nearly every part of the body.


 * 7. ** ﻿ Bone marrow is a substance thats inside of bones. The marrow can be stored inside of the bone, or it can just flow through. The fuctions of Red bone marrow makes red and white blood cells.

**8.** ﻿Osteoarthritis is a joint disease that mostly effects cartilage marrow that stores fat. The main causes of osteoarthritis is damage to the joints brought on by lifelong use, family history. There is no specific cure for this disease, but you can treat it with drugs.
