Muscles
Structure, Function, Training
When we talk about muscles, we mostly think of those we can see. These are the arm, chest, abdominal and leg muscles. The muscles have to fulfil various tasks in the human body. On the one hand, they serve the movement and upright posture of our body, on the other hand, the contraction of hollow inner organs such as the intestine, bladder and blood vessels. The third task is maintaining blood circulation.
