The roles of the body systems within the human body are very significant and they contribute to help maintaining certain functions within the body. Without the systems, our bodies would not operate to their full extent and we would struggle on a day to day basis. The skeletal, digestive and reproductive systems are just three body systems that help us to maintain some of these functions.
The key responsibilities of the skeletal system are to protect, support, give shape and allow movement. The skeletal system is made up of bones, ligaments, muscles and joints. These components work together to provide us with these functions. Joints are where two bones meet and they are filled with a fluid which allows for smooth mobility at the joints. For example, the knee allows us to bend up and down and walk. The skeletal system allows for us to be supported and gives us shape. Two examples of this is that the cranium protects the brain and the rib cage protects the lungs and heart. Muscles contract and this causes the bones to manoeuver allowing us to perform certain actions such as running and jumping. Without the skeletal system, we would be flaccid.

The digestive system consists of the mouth, oesophagus, stomach, pancreas, liver, gall bladder, small intestine and the large intestine. The breakdown of carbohydrates, proteins and fats within the system means that they can be absorbed into the blood. It also allows for us to excrete harmful toxins from our body leaving only the goodness behind. If you had no digestive system, you would have no ability to get the nutrients and sugars in food and this could lead to anaemia or potentially a more serious condition such as type two diabetes therefore making the system a very important one within the
