Verified step by step guidance1
Understand the primary functions of skeletal muscle tissue: Skeletal muscles are responsible for producing voluntary movements, which are movements under conscious control, such as walking, running, or lifting objects.
Eliminate incorrect options: Skeletal muscle tissue does not secrete digestive enzymes, as this is a function of glands like the salivary glands or pancreas.
Eliminate incorrect options: Skeletal muscle tissue does not pump blood throughout the body; this is the role of cardiac muscle tissue found in the heart.
Eliminate incorrect options: Skeletal muscle tissue does not transmit nerve impulses; this is the function of neurons in the nervous system.
Conclude that the correct answer is 'Producing voluntary movements,' as this is the primary function of skeletal muscle tissue.
