Muscular System

Function: 

Allows the body to move. (Really it moves your bones)

Organs: 

Cardiac (involuntary only found in the heart), Smooth in voluntary bladder, intestines, stomach and diaphragm.

Veins and Arteries:
Cardiac muscles provide the main force for circulation of blood throughout human body. 

Interaction with other Systems:
The muscular system works with the skeletal system to help with the movement of your body parts, the muscular system decides when to move it. They work in sync with each other as the muscular system moves it and the skeletal system provides the structure for your body. It also works with the nervous system because it sends the orders of when to move and when not to move. It also works with the circulatory system because it provides the blood for the muscles to work.

Analogy:

The muscular system is like the motors of this robot arm because it assists in movement while the skeletal system provides the structure of the arm like for other things like cars, computers, or phones. 


Structure and Function:

Skeletal muscles are the main muscles for moving in your body like picking up a coffee cup or typing up a report. These muscles are the ones that assist in moving your bones. Without these muscles you would be a statue not able to move around like we do now. If you didn't have these muscles you would probably be dead because you would not be able to grab a bottle of water or have dinner with your grandma without your skeletal muscles. Without the skeletal muscles you would be a living statue because the bones would the holding you up but with no muscles you wouldn't be able to move around. So that is why you need your skeletal muscles to move around to assist you in life.
