What is the main purpose of the muscular system?

• A. To filter disease-causing organisms
• B. To support hormonal functions
• C. To permit movement of the body
• D. To circulate blood

Answer: (C)

The main purpose of the muscular system is to permit movement of the body. This system is composed of muscles that work together to facilitate voluntary and involuntary movements, allowing us to perform a wide range of activities such as walking, running, stretching, or even maintaining posture. Muscles contract and relax in response to signals from the nervous system, enabling movement and interaction with our environment. The muscular system plays a fundamental role in locomotion by working alongside the skeletal system, as muscles are attached to bones via tendons. When muscles contract, they pull on bones to create movement at joints, allowing for coordinated action across the body. While the other options address important bodily functions, they do not define the primary role of the muscular system. Filtering disease-causing organisms pertains to the immune system, hormonal functions relate to the endocrine system, and circulating blood is a function of the cardiovascular system. Therefore, the unique responsibility of the muscular system is centered on facilitating movement.
