Answer:
The two body systems that work together to provide body movement are skeletal and muscular (option A), because the first one provides support to the body and the second one is in charge of producing the contraction that allows mobility.
Explanation:
Due to their joint action to produce body movements, the skeletal and muscular systems are grouped as a musculoskeletal system.
- Skeletal system is made up of rigid organs, called bones, and is responsible for supporting the body. The union of the bones is done through joints, which allows a certain range of movement, especially in the neck, trunk and upper and lower limbs.
- Muscular system is formed by the striated muscles, organs made up of fibers with contractile capacity.
The muscles are attached to bone surfaces, and their location depends on the movement that will have the skeleton and, consequently, the body.
The other options are not correct because:
B. The circulatory system helps to bring blood to the muscles, but is not directly involved in the production of movement.
C. The digestive system is in charge of preparing the nutrients for their absorption, through the process of food digestion.
D. The nervous system controls all the corporal functions, including the movement, reason why it participates of indirect way in the corporal movements.
