Question

Quizplus · Accepted Answer

Smooth muscle can hold contractions longer than skeletal muscle, making it well-suited for organs like the digestive system that need to maintain prolonged contractions to move substances through the body. Additionally, smooth muscle requires less ATP than skeletal muscle, making it more energy-efficient. Smooth muscle is not limited to the digestive tract and can be found in other organs such as the uterus and blood vessels.
