A nervous, muscular, skeletal
B respiratory, muscular, digestive
C skeletal, circulatory, immune
D digestive, nervous, circulatory
answer: A.NERVOUS, MUSCULAR, SKELETAL
The three human-body systems coordinateto cause an arm to move are the nervous system, muscular system andskeletal system.
To simplify, the brain will signal the whole body to move the arms, nerves onthe muscular will respond by making the bones of the arm move.
Nervous system recognizes as well as coordinates the response of our body tochanges in its internal and external environments. While, the muscular systemis working with our skeletal system to produce voluntary movement as it alsohelps to circulate the blood and move food through the digestive system. Lastbut not the least is the skeletal system that supports the human body. It infact protects human’s internal organs and also allows movements. Our skeletalsystem stores mineral reserves and provides site for the formation of our bloodcells.

Letter B respiratory, muscular, digestive - incorrect because, the respiratoryregulates the breathing of the body while digestive system is being used whenwe are eating and / or defecating. Lungs and stomach aren’t involved when weare moving our arms.
Letter C skeletal, circulatory, immune – is incorrecttoo because circulatory system and immune system are for the regulation of our blood,cells and immunity.
Letter D digestive, nervous, circulatory – is incorrect,too. Rely on the explanation for Letter B and Letter C.

Nervous system includes brain,spinal cord, and somatic nerves and all sensory organs.
It also includes those that serve senses such as vision, smell, sensation,balance, hearing and taste.
Nervous system is of course involved in moving our arms as it coordinates bodymovements and controls responses to both external and internal stimuli.
It can serve as the center for our intellect and memories that can alsoregulate moods and provides mechanisms for human interaction.
Muscular system includes skeletal muscles.
It is involved in moving our arms because muscular system provides locomotionand support as it allows us to manipulate our atmospheres as it could producesheat, too.
Skeletal system this includes bones, joints,cartilage, tendons, and ligaments.
Skeleton provides structural protection for our internal organs and this is whyit is involved in moving our arms.
Skeleton or our bones are like the reservoir for calcium, phosphorus, andmagnesium that are crucial in array of physiological processes.
