Explanation:

The text describes different types of muscles. Smooth muscles line body passage - ways and hollow organs, are involuntary, and are found in the digestive tract, blood vessels etc. Skeletal muscles are attached to bones, cause body movements, have a striated appearance, are mostly under voluntary control, and work in antagonistic pairs (flexors close joints and extensors open joints). Cardiac muscle is a type of striated muscle that forms the heart wall, is involuntary, and the heart contracts rhythmically about 100,000 times a day to pump blood.
