Verified step by step guidance1
Identify the primary functions of the muscular system. The muscular system is responsible for movement, posture maintenance, and heat production.
Understand that muscles work by contracting and relaxing, which allows for movement of the body and its parts.
Recognize that while the muscular system contributes to heat production through muscle activity, its primary role is facilitating movement.
Differentiate between the functions of different body systems: the skeletal system provides structural support, the circulatory system transports oxygen, and the integumentary system regulates temperature through sweat.
Conclude that the primary function of the muscular system is to facilitate movement by contracting and relaxing muscles.
