A) The digestive tract. B) The muscles in your legs.
Smooth muscle is usually in the parts of our body that are involuntary; that is, the parts that we don’t have to think about. For example, we don’t have to think about our stomach digesting our food, or our small intestines moving the food along by peristalsis. These are examples of smooth muscle.
Skeletal muscles are the large muscles that allow for voluntary movement. The quadriceps in the front of your thighs, the hamstrings in the back of the thighs, the gastrocnemius in the calf, your biceps and triceps in your arms, your pectorals in the chest, latissimus dorsi that let us bend side to side – all of these are movements that we consciously choose; these are all skeletal muscles.
