Muscular System Courtney Kiestler And Devin Bowles

Major Organs There are three types of basic muscles: skeletal, cardiac, and smooth, The skeletal muscles help move bones. The cardiac muscles help your heart pump blood. The last muscle is the smooth muscle, which are found in your intestines, bladder, blood vessels and other internal organs. The heart is also a main organ that pumps the blood through your body. These are some main muscles in your body.

Functions and processes Muscles help you move. Over a period of time, muscles can become larger or smaller depending on whether or not they are used. For instance, if you laid around an watch TV all day, your muscles are not used that much. They need energy to contract and relax. When one muscle moves on contracts, the other muscle relaxes. This shows triceps and biceps relaxing and contracting.

How does it relate to other systems? Without muscles, you wouldn't be able to move. Since they help bones move, you would be stiff if you didn’t have muscles. They help the skeletal system.It shares organs, like the heart, with the circulatory system. The heart
