There are three main functions of the muscular system. 1. Warmth – your muscles warm you up by shivering 2. Movement – the muscles make your bones move so you can walk, jump, wave, etc 3. Posture – the muscles generate a low amount of force to hold the body up for long periods of time – like holding your shoulders back.

To keep the muscular system healthy you need to:- 1. Exercise every day 2. Eat healthy foods and make sure you eat the recommended amount of protein, carbohydrates and fats 3. Reduce stress in your life

If the muscular system didn’t work you wouldn’t be able to  Talk  Move  Breathe  Eat Basically you would not be able to survive on your own.

 Skeletal system – by making the bones move so we can run, walk, lift etc  Digestive system – in the stomach and digestive system the muscles tighten up and relax so the food can travel through the body  Respiratory system – muscles make our lungs contract so we can breathe

 The body has more than 600 muscles  There are three types of muscles. They are:- › Smooth › Cardiac › Involuntary Some muscles are connected to the bones Muscles make up nearly half our body weight
