Which of the following is NOT an important function of the components of the muscular system?

movement of organs

mechanical protection

heat generation

vitamin storage

The correct answer is D. Vitamin storage

Explanation:

The muscular system includes three different types of muscles (smooth, cardiac and skeletal) that provide movement to the body, including non-voluntary movement in organs, protect inner organs and regulate temperature as muscles generate heat through movement and contractions. However, vitamin storage is not part of the functions of this system as substances such as vitamins and minerals are stored in other organs and tissues such as the liver or the fatty tissue.

D. Vitamin storage.
