Verified step by step guidance

Understand the three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscle is voluntary, meaning it is under conscious control. Cardiac and smooth muscle are involuntary, meaning they function without conscious control.

Cardiac muscle is found in the heart and is responsible for pumping blood throughout the body. It contracts automatically and rhythmically, making it involuntary.

Smooth muscle is found in the walls of hollow organs such as the intestines, blood vessels, and bladder. It helps move substances through these organs and operates involuntarily.

Skeletal muscle is attached to bones and is responsible for voluntary movements, such as walking or lifting objects. It requires conscious control to function.

Based on the definitions, identify the correct answer as the types of muscle tissue that are involuntary: cardiac and smooth muscle.
