Muscles run throughout the human body. Each muscle has a specific name according to it's location or function. All these muscles work and render human body to function normally. For example, when you want to play flute you have to pucker your lips, you can do so with the help of Orbicularis oris, a muscle surrounding the lips.

.Explanation:
Pain or discomfort in the stomach associated with difficulty in digesting food is called indigestion.
