Which type of muscle tissue is responsible for movement and protection of internal organs?

The correct answer pertains to smooth muscle tissue, which is indeed responsible for the movement and protection of internal organs. Smooth muscle is involuntary and is found in the walls of hollow organs such as the stomach, intestines, blood vessels, and bladder. Its primary function is to contract and help move substances through these organs, contributing to essential processes like digestion and circulation.

Skeletal muscle, while also responsible for movement, is primarily involved in voluntary movements of the body, such as walking or lifting objects, and does not protect internal organs in the way that smooth muscle does. Cardiac tissue is specialized muscle found only in the heart, responsible for pumping blood throughout the body, but does not cover or protect organs. Conversely, connective tissue plays a supportive role in the body but is not directly involved in movement or organ protection. This is why smooth muscle is the most appropriate answer in the context of the question.
