Smooth muscles are also known as an involuntary muscle. An example if this is your heart, your heart beats by itself.
Cardiac muscles are found in your heart, where it performs coordinated contractions that allow your heart to pump blood through your circulatory system.
Skeletal muscles are attached to your bones by tendons. They are the opposite of smooth muscles, they are voluntary muscles. This means that they help you do everyday tasks such as walking.
